Bulletin 36: Viper Additive Injection Systems

Viper Additive Injection Systems

For most any additive in any fuel

Viper Additive Injectors are designed to accurately and reliably inject a wide range of additives into a flowing stream of fuel or other hydro-carbon liquid. All fluid-wetted components are 300 series stainless steel. For maximum accuracy, temperature range, and durability, we have a wide range of custom rubber seals available.

Available with or without controls, these injectors can be directly controlled by the new advanced LC, TCS, and other meter computers for simplicity and record keeping. Made in USA.

Viper Pump

The Viper pump is a simple concept. A double-acting, positive displacement, solid stainless steel piston pump, tested to provide a long life on clean additive before seal change of 30,000,000 gallons. All rubber (check valve) and PTFE (shaft and piston) seals, for reliability and accuracy. Self-cleaning check valve design, inlet strainer and main seal leakage detector. Compressed air powered, electronically controlled.

Our Heavy Duty mechanical adjuster is linear so if you change the adjuster 10%, the additive output changes 10%, unlike some competitors. Tested to -50° F. Viper pumps in service as long as 15 years have never needed adjustment, just occasionally new seals or a strainer cleaning. Checking is simple, flow volume into a test jar is the same as flow into the fuel stream.

Flow rates up to 1,200 gpm, additive rates up to 1,500 ppm. Includes a special test valve, high-visibility flow indicator, and atomizing injector nozzle.

Viper Scorpion & Scorpion Mini

The Viper Scorpion is a smaller version of the Viper. Flow rates up to 500 gpm at 100 to 1,000 ppm. Compact and less expensive, but just as accurate and reliable.

The Viper Scorpion Mini is a simplified additive injection system without mechanical adjustment. Developed for use specifically with a meter computer such as the TCS or LC system. Additive meter required.

Viper Concord

The Viper Concord was developed long ago to inject CI/LI additive for the Concord SST. Designed to accurately inject additive at as low as 20 ppm at flow rates up to 1,000 gpm, the Concord was “brought out of retirement” to join the Viper line. Interestingly, the Concord has no Piston seal, utilizing a clean “return” design to prevent leakage.

Digital Viper and Viper Eclipse Control System

The “brain” is a simple control, preset before shipment. No programming needed! The Digital Viper takes a pulse from your existing meter, and paces the additive flow rate to match the fuel flow. When interfaced with an on-board meter computer, can inject additive at different ratios for different customers, simply! A very simple system, using robust parts specifically built for this purpose.

The Viper Eclipse builds on the Digital Viper. It has a more advanced brain and a digital display. But don’t worry about programming, we do it all, no field programming needed. It has self-checking and self-adjusting ability, as well as a digital display with ppm, percent, gallons (or liters) of fuel and gallons (or liters) of additive displayed. It has warning and shutdown modes if additive concentration falls out of the set range. Includes additive meter calibration and priming modes. The Eclipse adds an additive meter and an intelligent “permissive” control system. The operator cannot dispense fuel without first telling the Viper Eclipse to inject, or not to inject additive. No more “forgetting” to turn the injector on or off. Maintaining a 1,000 operation memory of additive and fuel dispensed, date and time.

The Viper Eclipse Control System can be used with any of the Viper pumps.

Bulletin 25: Gammon Gauge

Gammon Gauge™

Direct Reading Differential Pressure Gauge
Why settle for less when you can have the tried and true original?

Unique Features

Common Features of all Models of the Gammon Gauge™

  • Read differential pressure directly at top of piston

  • Accurate within 1/4 psi at system pressures to 300 psi

  • No subtraction calculation required

  • All models available in aluminum or stainless steel
  • Positive and negative surge pressure will not influence calibration
  • Multiple calibrations: PSI and Kpa (front face), Bar and KG/cm² (back face)

  • Every cylinder tested at 1200 psi
  • Rugged construction – suitable for vehicle or stationary use
  • Built-in gauge protection filter, 10 microns
  • Maximum operation pressure of 300 psi
  • Fittings: 1/4” NPT female, 1/4” BSP available
  • Temperature range of standard Viton GLT seals: -40°F to +400°F (-40°C to +204°C)
  • Ultraviolet light protection – film face cover prevents rays from degrading fuel in the glass tube
NOTE: The GTP-279 filter is obsolete. We offer a conversion assembly GTP-9515-1 (S/S) or GTP-9515-2 (AL). This is a complete replacement for the upper flange.

Calibration Testing

To meet API-1581, you should have a 3-way valve. Our 3-way valve meets this requirement and is used to check calibration as well as to check free movement of the piston.

  1. Establish flow in the system. The gauge should indicate a pressure drop.
  2. Push the test button. The piston should travel to the bottom of the scale.
  3. Release the button and stop flow in the system. The piston should return to zero.

If the piston returns to zero, you have not only calibrated the gauge, you have checked it for free moment across its entire range. If the piston moves slowly, the filter (located in the top of the gauge) may be clogged and need replacement. This calibration technique is accepted by all major oil companies, all major airlines, and military services worldwide. Gammon Gauges™ have been in service in virtually every major airport in the world for as long as 30 years and we have never heard of or seen a single gauge go out of calibration. Occasionally a piston will stick after many years in service, but hand cleaning with “Scotch Brite” plastic abrasive will make it as good as new (Note: Do not clean with sandpaper or steel wool). Replace the o-rings and reassemble.

Gammon Gauge™ Control Systems

Protect Against Filter Element Bursting
Add a Differential Pressure Switch to the Gammon Gauge™
Sound Alarm – Stop Flow – Turn on Second Filter
Normally Open or Normally Closed, Fail Safe

If differential pressure suddenly increases or a facility is operated without personnel monitoring the differential pressure, filter element failure can occur. This new switch is unique. It adds differential pressure control at a low cost using a non-powered proximity switch. This simple double-sealed switch is ideal for use in PLC (miniature computer) and relay controlled systems. The connection box is rated NEMA 4X.

Control operations are also available if you don’t plan to use an external control. We have weather-tight and explosion-proof versions.

We strongly recommend a 3-way test valve for properly testing the Gammon Gauge™ and Proximity Switch and/or system.

Any Gammon Gauge™ can be converted to include the new proximity switch.

Note: To meet IATA JIG Bulletin 58, order one of the “KS” options for key switch reset and test functions. The ATA-103 does not require this. For vehicle mounting, we recommend the weather-tight housing.

Notes:

  • GTP-8980 has a normally open switch. The switch closes upon high differential pressure. If the cable to the controller is cut, high differential would never be detected.

  • GTP-8980B has a normally closed switch. The switch opens upon high differential pressure. If the cable to the controller is cut, the system would go into alarm notifying the operator that something is wrong with the system.

  • If a system is purchased without the controller (no enclosure), both types of switches are still available. When a complete system is ordered with an enclosure, it is our policy to provide a GTP-8980B fail safe system unless otherwise requested. The difference is in the internal wiring and components in the controller.

How to Order

Examples

GTP-8980B-C-RH-12-B-0 is a differential pressure gauge with a normally closed switch as follows: push button aluminum gauge, 30 psi scale, switch on right side, 12 VDC, enclosure is weather tight which includes light and push to test feature, no solenoid valve, and low temperature o-rings.

GTP-8980B-C-RH-12-BKS-0 is the same as above except the enclosure has 2 key lock switches for test and reset per IATA JIG Bulletin 58.

Bulletin 22: Sump Separator for Storage Tanks

Sump Separator for Storage Tanks

Model GTP-616

GO GREEN – removes water and dirt, saves good fuel!

The Sump Separator separates water from fuel that is drained from storage tank sumps. The fuel and water mixture from the bottom of a storage tank or from the sump of a filter is discharged to the Sump Separator through a nozzle that causes a swirling action to concentrate most of the dirt in the center of the cone-shaped bottom. Water and fuel are allowed to separate by gravity.

The Gammon Sump Separator:

  • Prevents fuel contamination of ground water.
  • Allows for pollution control of soil and streams.
  • Saves valuable fuel.
  • Requires minimal maintenance.
  • Eliminates the need for conventional waste or “slop” tanks.
  • Features an internal epoxy white coating (stainless steel available on request).
  • Has a capacity of 50 gallons standard & up to 300 gallons on special order.

CLEAN CUT
Only the Gammon Sump Separator makes possible a clean cut. The operator can easily see when the fuel/water interface has reached the bottom of the cone. When closing the water drain valve, the operator makes a clean cut, preventing any fuel from leaving with the water. Only fuel remains at the bottom of the cone.

VISUAL CERTAINTY
Direct visual observation of the fuel/water interface is achieved by swinging the cover on its davit so that the operator sees through the fuel to the interface. This provides visual certainty to make a clean cut.

Other sump separator designs on the market rely on a sight glass that the operator observes when draining off the water. Invariably, some of the fuel leaves with the water because the level in the sight glass always lags behind the level in the vessel. The operator can overcome this problem by closing the water drain valve ahead of time. The result is that some of the water is then pumped back to the storage tank.

Gammon originated the sump separator in 1965 and has always used a stainless steel foot valve at the bottom of the cone as shown on page 2. All other manufacturers use common pipeline valves that cause some of the settled water to be pumped back to the storage tank.

No other manufacturer in the world can claim more than 50 years of experience in the sump separator business. In fact – we originated the name “sump separator”!

Not recommended for gasolines or other, low-flash point fuels.

Ordering Information

NOTE: Sump separators cannot be ordered online. Please contact us to get a quote or place an order.

All models include the following:

  • 1 in. ball valve at inlet

  • 1/2 in. ball valve at water outlet

  • Cover with swing-away davit style mount

  • Two 3/4 in. auxiliary fittings for connection of discharge piping from air eliminators, pressure relief valves and drains from filter separators

  • Two 1/2 in. auxiliary fittings for connection of sight glass

  • Foot valve, o-ring sealed; releases fuel for return to storage (1 in. NPT port)

  • Pipe and fittings: steel or ductile iron. Cast iron not used. Stainless steel available upon request.

  • Valves are brass ball type. Stainless steel available upon request.

Base Models

GTP-616A
Model GTP-616A

Use for underground storage tanks. Fuel returns to storage by gravity when foot valve is opened.

GTP-616B
Model GTP-616B

Use for above-ground storage tanks that will gravity drain to the sump separator.

Includes a 10 gpm, 65 foot head ductile iron centrifugal pump with explosion-proof switch, (120 volt, 60 Hz, 3/4 Hp, single phase, explosion-proof motor) to return fuel to storage.

Options

Option 1

Adds discharge swing check valve.

Option 2

Piping connected to pump fuel back to storage through the storage tank drain line.

Option 3

Adds a filter rated at 1 micron, 150 psi design. Recommended only for GTP-616B.

Option 4

Adds connection with 1” ball valve and swing check valve. Use for draining filter tanks when elements are to be replaced.

GTP-616B-5
Option 5

Same as Option 4, except bypass piping also included. When draining a filter tank with a capacity greater than the 50 gallon sump separator, the first 50 gallons will flush out the filter sump water and dirt. The excess can then bypass the sump separator and go directly to storage.

GTP-616B-4-6
Option 6

A positive displacement pump is added to either Option 4 or 5. Pump will self-prime and draw fuel from a low filter sump, an underground storage tank sump, or from a mobile filter having a hose connection. Includes explosion-proof control box (120 volt, 60 Hz, 3/4 Hp., single phase, explosion-proof motor). When ordered on Model B, circuit arranged to prevent both pumps operating at one time.

GTP-616B-7
Option 7

Adds oil bath heating system under the cone-shaped bottom. Includes explosion-proof thermostat, switch and indicator light. 300 watts, 220 volts.

GTP-616A-8
Option 8

Adds 40” sight glass with fittings and ball stop, to prevent flow if glass breaks. Option 8SS is stainless. Option 8B is bronze.

Example Combinations

Model GTP-616A47

This is a sump separator for use with an underground storage tank. No return pump is required because the fuel will drain by gravity back to storage. A connection has been added for taking the drained fuel from a filter and the cone bottom is equipped with a heater.

Model GTP-616B1246

This sump separator is for use with an above-ground storage tank and is equipped with a pump, check valve, and return piping so that the fuel can be pumped back to the storage tank through the storage tank drain line. A connection has been added with a positive displacement pump for taking the drained fuel from a filter that has a sump that is lower than the sump separator.

Bulletin 14: Jet Test QD

Testing During Refueling with the Jet Test QD®

A miniature, permanently installed quick disconnect coupler for testing during jet refueling operations

Backed by 40 years of successful performance all over the world, the Jet Test QD® is a proven concept in Quick Disconnect Couplers for performing tests for dirt, water, and pressure regulation during the refueling of jet aircraft.

The Jet Test QD® is so small that it can be installed permanently on the underwing fuel nozzle. Prior to the introduction of this product, a pressure or contamination test at the nozzle could not be performed without considerable fuel spillage while a connection was fabricated at the plugged port.

Uses for the Jet Test QD®

Perform a contamination test with the Gammon MiniMonitor® Kit (or Millipore Test Kit). Just twist out the dust plug with a coin and insert the test apparatus. It takes only 15 seconds.

SEE BULLETIN 8

Perform a water test with the Gammon Aqua-Glo®. A complete test can easily be performed, including dust plug removal and replacement well within three minutes.

SEE BULLETIN 86

Perform a pressure test while refueling the aircraft. It takes only a few seconds. Simply twist the dust plug with a coin and pull it out, then insert the test gauge and twist to lock on the bayonet pin.

SEE BULLETIN 46

Couplers

The exposed portion of the Jet Test QD® coupler is no larger than a standard hex head pipe plug, yet it contains an inner or primary seal as well as an outer secondary seal which is created by the dust plug.

See the table below to determine the appropriate coupler for your application.

The three couplers shown here are pictured with the standard knurled dust plugs.

GTP-235-3/8

GTP-235-3/8S

GTP-235-3/8AH

Dust Plugs

This is a dust plug that is also a secondary pressure seal. It is removed only when a test is to be run. GTP-235-9K is the standard plug for the GTP-235-3/8 coupler. GTP-235-9SK is the standard plug for the “AH” and “S” couplers. The standard plug is included unless otherwise specified. If the tee handle plug is desired, the customer must specify (GTP-235-9T for standard length, or GTP-235-9ST for “AH” and “S” couplers).

GTP-235-9K

GTP-235-9K

Actuators

The actuator should be attached permanently to the test apparatus or pressure gauge. The standard actuator is GTP-235-2. A short version, GTP-235-2AH, is available to fit the “S” and “AH” couplers. Both actuators have 1/4” NPT threads.

Insert the actuator nipple, and rotate a quarter turn to lock on the bayonet pin. The internal valve automatically opens and a test can be performed.

Bulletin 8: MiniMonitor & MultiMiniMonitor Kits

MiniMonitor® Kit – Mark II

The Mark II version has the unique advantage of eliminating the “white spot.” This photograph of a filter membrane shows how all previously manufactured test kits, regardless of the brand, make a white spot in the center if the inlet pressure is high and the fuel sample is contaminated. The jet effect causes the white spot.

In the new Mark II design, the inlet fuel to the plastic monitor is dispersed laterally to ensure a more uniform distribution of particles over the entire surface.

The MiniMonitor® Kit is used to test aviation fuel for particulate contamination using the procedures described in ASTM D2276/IP216. A measured volume of fuel is passed from a flowing pipe directly through a 0.8 micrometer membrane. The plastic monitor holding the membrane is placed in an aluminum housing. Dirt particles are caught on the membrane which can be visually color rated or weighed for a gravimetric rating.

The Mark II’s lateral distribution is created by a unique discharge tube that enters the plastic monitor, as shown in this drawing. The large area of the four holes ensures that the flow rate is not affected.

The MiniMonitor® Kit was developed by Gammon Technical Products, Inc. specifically for aircraft fuel testing with standard field monitors. This kit, including the carry case, weights only 4 pounds.

The new style of carrying case provides a cavity which accepts the assembled kit, eliminating the need to disassemble each time the apparatus is stored.

MiniMonitor equipment uses standard plastic monitors listed by ASTM for Method D2276/IP-216.

The MiniMonitor® housing includes a flushing valve located on top of the monitor with a bypass hose and fittings. Before flushing the sample connection, move the arrow located on the flushing valve handle to the STOP position. Check the connections of the bypass hose for firm seating. After the connections have been checked, move the arrow to the FLUSH position and allow one gallon (or specified volume) to collect in a measuring container. Then turn the valve to the TEST position to direct flow through the filter membrane. This test volume may be from 1 to 5 gallons depending upon contract provisions. The membrane is then rated as to its color using the color rating booklet included in the kit. The darker the membrane, the dirtier the fuel. Some contracts require the weight of the contaminant to be determined. The same apparatus can be used but arrangements must be made with a laboratory.

Electrical bonding is a safety requirement of ASTM Method D2276/IP216. Our Bonding and Grounding Hose Assembly clips to the metal container (not shown) and also to the pipe fitting as shown in the photo.

Bulletin 3: Fuel Sampling Kits

Fuel Sampling Kits

Our fuel sampling kits have become the standard in the industry for obtaining test samples of jet fuel. With more than a million in service, they have proved to pay for themselves by saving countless hours of downtime because accurate contamination test results are obtained the first time.

In the past, thousands of work hours have been wasted and fueling facilities have been shut down simply because the sampling tap was contributing dirt during the sampling period. Rusty pipe threads, steel gate valves and collections of reducing bushings that are never subjected to fuel flow, except when a contamination test is to be run, have been found to be a prime cause of poor color results when tests are performed to ASTM D2276. Flushing does not clean normally stagnant steel fittings.

Our probe penetrates through the pipe coupling that is welded to the pipe. There is no possibility of rust and dirt, that usually collects in stagnant pockets (such as welded couplings), reaching the test membrane.

Non-ferrous materials are used in our kits, All passages are small (¼” pipe size) to insure that there will be enough velocity during the flushing cycle to carry away any sediment that may have collected.

Kit No. 7T allows pressure sensing and sampling independently through one pipe connection. Probe penetrates all the way through the tee. Sample never contacts the tee. Branch on tee is for pressure gauge connection; it senses pressure on the inside of probe tube.

Kit No. 8 features our Self-Flushing QD, which eliminates the need to flush the connection before every test. It will only allow fuel from the center of the pipe to reach the QD. This reduces the amount of time spent and the volume of fuel that has to be handled. For panel mounting, Kit No. 8RM includes Kit 8 plus a remote mount (standard probe sizes only).

The GTP-144 Probe is made to reach the center of a 4” pipe but can be used in any pipe of 2” or more. The threads on the probe are both ¼” NPT male (use reducing bushing to come down to this size). We can also supply special probes of any specified length up to 6”.

Instructions for Sampling Probe Kits

  1. INSTALLATION
    1. Screw the GTP-144 probe in a ¼” NPT female thread using 1½ wraps of PTFE pipe thread sealant as a sealant and thread lube. Use reducing bushings if necessary. Wrap the tape tightly, so that it forms itself into the male thread. Do not let the tape extend beyond the open end of the fitting or fragments of the tape will get into the flow stream. NEVER screw stainless steel threads together without PTFE tape – they will gall.
    2. Adjust the position of the probe by tightening until the arrow on the flat of the hex is pointing downstream – in the direction of flow in the pipe.
    3. Install other components of the kit using PTFE pipe thread dope for each connection. Be certain that sample flow is in the correct direction.
    4. The sampling coupler is supplied with a dust plug that has a lanyard for attachment. Place the lanyard before assembling.
  2. FLUSHING – A new sampling connection requires extensive flushing. For best results, use the GTP-1110 Bonding and Grounding Hose (see Bull. #8) to obtain high velocity in the passages of the sampling kit components.
  3. CONTAMINATION TESTING – Use Gammon MiniMonitor® Kit model GTP-172. Follow detailed instructions for best results. The sampling coupler can be connected without the risk of spraying fuel, if this procedure is followed:
    1. Slide the collar of the coupler as far as it will go toward its threaded end. Remember, the collar does not open the internal valve.
    2. Insert the connecting nipple in the open port of the coupler as far as it will go without depressing the internal valve, but continue to hold the collar.
    3. Then quickly press the nipple straight in with a force of about 25 lbs. and pull the collar back to its original position. This 25 lb. force causes the internal valve to open.
    4. A dry disconnection can be made simply by depressing the collar.
