Built-In Combination Valve EliminatesCost Of Separate Bypass Valves
Built into the LGF1 & LGB1 Series pump is a patented“combination” valve acting as a back-to-tank bypass valve &as an internal relief valve. This feature lowers installation costsby eliminating the need for a separate bypass valve. It alsoassures pressure relief if the back-to-tank bypass line isclosed. The valve’s unique three-stage operation is illustratedto the right.

Side Channel pumps are used in LPG applications where high differentialpressure is necessary or low NPSH conditions exist, such as pumpingfrom underground tanks, the SC-Series multistage side-channel is thepump of choice. The Side Channel pump is offered in six different sizes, each ranging fromone to eight stages. This provides for a wide range of pressures,capacities, and liquid transfer rates.The Corken SC-Series pump line utilizes an integral centrifugal and sidechannel design to create flow characteristics which enable the pump tohandle up to 50% vapor and low NPSH conditions. The multi-stagemodular side channel design which features one to eight open radial-vaneimpellers is capable of building differential pressures of over 200 psi. TheSide Channel pump casing comes standard as Ductile Iron with an optionof Stainless Steel. The impeller material comes standard as Brass but canbe ordered as either Steel or Stainless Steel.
* Normal maximum bypass flow rates without significantly exceeding the setpressure limit.
Bypass Valves
For Bobtail ServiceThe TLGLF3 pump series flange mounts directly to the trucktank in combination with a flanged internal control valve.Because it eliminates the intake line and related restrictions toflow, it also eliminates the vaporization problem caused bythem. That means longer pump life and higher effective pumpcapacity. The pump is rated to 125 psi differential.
The TLGLF3 pump is suitable for both LP Gas and anhydrousammonia. A double shaft extension is standard, making thepump suitable for either right or left-hand PTO rotation. Thepumps is equipped with replaceable cylinder liners and enddiscs, permitting rebuilding of the pump to like-new condi-tions.
For Transport ServiceThe TLGLF4 series transport pump is designed to mount to4" internal valves. It is suitable for both LP Gas and anhy-drous ammonia service. Ideal intake conditions assuremaximum pumping rates and the shortest possible transportturnaround time. An auxiliary intake port next to the mountingflange can be used for emergency unloading of another tankor transport. Rated for differential pressures to 125 psi, thepump has twin discharge ports which permit the use of twohoses, if necessary to reduce pressure loss when unloadinginto restrictive receiving systems.

1 The chart shows approximate delivery rates as seen invapor equalized propane systems at 70°F (21°C) with nopressure loss in pump suction piping. The following willcause increased vaporization of the liquid in the pumpsuction, adversely affecting the delivery.
1. Restrictions in the suction piping such as internal valves,excess flow valves, elbows, etc...
2. Restriction or lack of a vapor return line.
3. Temperatures below 70°F (21°C).
This loss of delivery is not caused by the pump but is aresult of the natural thermodynamic properties of liquifiedpetroleum gases. See the GUIDE TO CORKEN LIQUIFIEDGAS TRANSFER EQUIPMENT CP226 for a completedescription of these phenomena.

Pump System Troubleshooting Guide
IntroductionMost LP Gas & anhydrous systems use pumps to move liquid fromone location to another. Unloading transport trailer tanks into plantstorage, loading delivery trucks, filling bulk tanks, engine fuel tanks,portable cylinders, etc. & pressurizing LP Gas vaporizers are only afew applications. A well-designed & properly installed pumpingsystem will perform well for some time, but eventually problems occurrequiring attention.
Determining the problem and fixing it will take time and be confusing,unless one knows clearly how to proceed. The purpose of thistechnical guide is to provide simple, guidelines for correcting LP Gas& anhydrous ammonia pumping difficulties.
The procedure includes a preliminary checklist to help find out if theproblem can be fixed without taking anything apart. Then, it showshow to zero in on more serious problems by using a few pressuregauges to pinpoint the cause.
Before trouble occurs, equip the pumping system for easy pressuregauge installation. Small manual shutoff valves can be installed atproper locations, with plugs inserted in the outlets. This allows simpleplacement of pressure gauges without removing the LP Gas or anhy-drous ammonia from the system at the time trouble occurs, saving alot of time and money. Pressure gauges should be installed temporari-ly when the system is first installed, and pressure readings recordedwhile the system is working properly. Then, in many cases, comparingpressures with original readings may tell what the trouble is.
The trouble is most likely in the inlet line. It could be:1. The pump may be running at a speed too low to develop differential pressure.2. An inlet strainer is clogged.3. A valve is partially closed somewhere in the inlet time.4. Ice has formed either in the bottom of the supply tank or somewhere in the inlet line. This is
common particularly when the tank has been hydrostatically tested or purged with steam & notcompletely drained & dehydrated.
5. If a Flomatic valve is used, it may not be opening for a number of reasons:a) Pressure in the tank to be filled may be considerably less than that in the supply tank,
making it impossible for the pump to develop sufficient differential pressure to open thevalve (simply throttle a manual valve on the discharge line to cause the pump to developenough differential pressure to open the Flomatic valve. As the pressure in the tank to befilled goes up, it will be possible to re-open the valve in the discharge line.)
b) The pump by-pass valve may be blocked open or have broken or damaged parts,preventing the pump from developing sufficient differential pressure to open the Flomaticvalve. (Pump outlet pressure must rise at least 21 PSI to open the Flomatic valve.)
c) The Flomatic strainer, filter, three-way valve or other element in the actuating line is clogged,or the activating line is kinked.
d) The Flomatic valve internal parts may be damaged or worn. (Refer to Rego installationmanual #A7884F-301 for flanged valves or #L-451 for diaphragm-type threaded valves forrepair instructions.)
6. If an internal valve is used, the main valve may not be opening due to insufficient equalization time,broken or damaged valve parts, valve lever in closed position or insufficient excess flow sizing.
NOTE: Meter pressure is not needed for this condition.
The trouble is most likely related to the pump or by-pass valve. It could be:1. The pump may have excessively worn parts.2. The internal by-pass valve in the pump may be
blocked open by foreign material, or may have brokenor damaged parts.
3. The back-to-tank by-pass valve may be blocked open byforeign material or may have broken or damaged parts.
4. The manual by-pass valve, if so equipped, may be open.NOTE: Meter pressure is not needed for this condition.
NOTE: Figure 1 shows where pressure gauges should be installed andprovides blank spaces to record pressure gauge readings from theoriginal tests.
The pressure gauges should not be used continuously, because vibra-tions and the ravages of weather cause their damage or ruin. There-fore, as soon as the initial tests are complete, it is best to close theshutoff valves, remove the gauges, plug the valves and keep thegauges in a safe place, ready for troubleshooting when really needed.Diagnosing a problem is easier if the original test results are available,but not essential. It requires more time and effort.
Be sure to obtain and keep available for quick referral the Manufactur-er’s Operation and Service Manuals for the valves, pump, meter and alloperating equipment in the system. To avoid delays, maintain acomplete stock of recommended spare parts on hand for quickrepairs.
Follow the steps as shown. Don’t assume the answer is knownbeforehand, or skip any applicable steps. Rather, be thorough and me-thodical, and in most instances, you will solve the problem. On theother hand, if you have done all of this and still haven’t worked out yourproblem, feel free to call Gas Equipment Company or EngineeredControls International, Inc. direct. We will do our best to help. Perhaps,between us, we will be able to solve your problem and add somethingnew to the procedure which could help everyone in the future.

Pump System Troubleshooting Chart
Final ResultsMake repairs or adjustments as needed, and test the system’s operation.Record a new set of test pressures for future reference, and other replace-ments for all space parts used. The system now is ready to return to service.
Basic AssumptionThe pumping system did work OK, but now the transfer rate isconsiderably less, or the system won’t pump at all.
Preliminary Review1. Check the supply tank liquid level. The transfer rate could be considerably
reduced if the level is low, due to bubbles in the line, because of insufficient liquidhead, or a vortex effect in the tank. Remember, reduction in the pumping ratefrom these causes will be more extreme in cold weather (tank pressures are low).
2. Examine the pump drive to make sure the pump is rotating properly. Inspect forloose drive belts, damaged or broken flexible couplings or universal joints,broken drive keys & damaged or inoperative power take-off or pump clutch, etc.
3. If the system is equipped with the Rego Flomatic Valve.a) Three-way valve handle should be straight out, allowing the valve to open.b) Check the position indicator on the Flomatic Valve when the pump is
running. If the indicator shows that the valve is open, the trouble must bedownstream of the valve.
Diagnostic TestsOpen all valves as required for proper pumping operation. Gauges shouldshow tank pressure, pump inlet pressure, pump outlet pressure and meterpressure to be equal.
Start the pump and observe all pressure gauges. Match results with conditionsA, B, C, or D. Follow the appropriate steps.
The trouble is most likely in the meter vapor eliminator or meter differen-tial valve. It could be:1. The meter’s vapor eliminator may be malfunctioning. If the valve at the
outlet of the vapor eliminator does not seat when the vapors have beenpurged, the differential valve downstream of the meter will not open. Suchfailure could be caused by a damaged vapor eliminator valve seat, foreignmaterial blocking the vapor eliminator valve, a leak in the ball float, or ajammed or binding linkage between the ball and valve.
2. The diaphragm could be ruptured, or other parts could be damaged or bro-ken in the differential valve downstream of the meter.
The problem is probably downstream of the pump. Look for a closed valve,or some type of blockage in the discharge line. It could be:1. The meter strainer may be clogged.2. A back check valve at the inlet of the meter may be blocked, closed, or jammed.3. The meter rotor may be jammed by foreign material, preventing it from mov-
ing properly, which would prevent or retard flow.4. The drive key on the meter gears may be sheared. (In this case, flow would
actually be moving through the meter but not registering.)5. The differential valve downstream of the meter may be closed due to dam-
age, foreign material or ice.6. If screw type hose fittings are used, it is extremely important that they be
installed properly. If not, it is possible that a flap of rubber may be cut fromthe inside diameter of the hose, acting as a back check. It can flap across thedischarge line, effectively stopping the flow.
7. Check the hose nozzle valve, if so equipped. In some brands, a bent handleor other defect may prevent the inner valve from opening sufficiently to allowa proper amount of flow.
8. The problem could be in the valve assemblies in the tank to be filled. If youare dealing with a delivery truck application, move to another tank and seewhether the problem still exists. If not, it may be a problem with one specifictank, rather than the pumping system.
9. Some delivery trucks are equipped with a quick-acting valve immediatelyupstream of the hose reel. Make sure that this valve is open.
10.Some delivery trucks are equipped with excess flow valves between themeter & hose reel. Improper sizing, a weak spring, or other valve damage cancause this valve to close prematurely, effectively stopping the flow.
11.If, with a delivery truck system, the flow reduced considerably while the tankis being filled, it is possible that the back-to-tank by-pass valve is not set highenough to compensate for vapor pressure buildup in the tank being filled. Thiscan be solved merely by adjusting the by-pass valve at a slightly higher level.
WARNING: Do not raise the back-to-tank by-pass setting high enough to causethe internal relief valve in the pump to actuate. Excessive cavitation, loss ofcapacity and premature pump wear can occur.

Final ResultsMake repairs or adjustments as needed, and test the system’s operation.Record a new set of test pressures for future reference, and other replace-ments for all space parts used. The system now is ready to return to service.
c) Make sure the priming valve is open, allowing pressure to equalize betweenthe tank and pump inlet.
4. If the system is equipped with internal valves, make sure the operating levermoves to a full open position. Repair if needed.
5. Make sure all valves in the system are either open or closed as required fornormal operation. Check each valve in sequence, starting from the supply tank,making sure that no valve element is missed.
If the cause of the problem has not been determined during preliminary review, itwill be necessary to conduct diagnostic tests, using pressure gauges at key pointsin the system.

Blackmer oil-free compressor for high performancetransfer and vapor recovery of Propane, Butane, Anhy-drous Ammonia and other liquefied gases.
Stationary Base MountingCompressors are factory mounted for all three of its oil-freecompressor models. The stationary base mounting includesliquid trap, four-way valve, belt guard, adjustable motor slidebase, V-belt drive assembly including motor sheave and hub,strainer, valves, pressure gauges and interconnecting pipingall mounted on a unit base.
Transport MountingBlackmer compressors can be transport-mounted. All modelsof Blackmer compressors may be adapted for either directdrive or V-belt drive applications.
* Double acting.** Compression Ratio defined as absolute discharge pressure divided byabsolute inlet pressure.*** Compression Ratios are limited by discharge temperature. High compression
ratios can create excessive heat, i.e. over 350°F (117°C). The duty cycle must provide for adequate cooling time between periods of operation to prevent excessive operating temperature.
1. Delivery will depend on proper system design, piping size and valve capacity.2. HP is for liquid transfer and vapor recovery in moderate climates. Consult
your GEC representative for HP requirements in severe climates. For liquidtransfer applications without vapor recovery, multiply by 0.4.
3. Use next larger pipe size if piping exceeds 100 feet.
* Indicates maximum RPM for respective motor HP.

Hydraulics
Drum Hydrapak Hydraulic Cooler
Hydraulic Drive Systems provide an alternative to drive shafts foroperating cargo pumps. Hydraulically driven pumps that requireextended use, such as unloading a transport, would not bepossible with a standard 30-40 gallon oil reservoir used in inter-mittent duty due to the lack of heat dissipation. The DrumHydrapak oil cooler makes this possible.A hydraulic oil cooler acts like a radiator on an automobile. Asthe oil passes through the radiator, a high volume fan cools thefluid making it possible to extend the duty cycle of the rotatingequipment.Features• Heavy Duty 316 Stainless Steel Main frame• Corrosion resistant aluminum radiator• Incorporates a standard spin-on design filter• Cooling fan driven by a high performance hydraulic motor• Light weight (MH1, 49lbs.; DH3, 110lbs.)• Filter restriction indicator monitors filter element conditionBenefits• Eliminates PTO shaft and universal joint maintenance• Close coupled hydraulic motor and cargo pump eliminates poor align-ment• Safer operation due to the elimination of exposed rotating equipment• “Soft Start” transmission of power produces prolonged service life of
cargo pumping system• Minimal maintenance is required - oil and filter changes twice a year• Truck and trailer alignment is not a concern• Hydraulic controls can be placed at convenient locations for clear
view of unloading hose• Hydraulic fluid will internally bypass if a mechanical problem occurs
eliminating damage• Small amount of hydraulic fluid is needed (MH1, 2 gal.; DH3, 3.5 gal.)• Built in the USA

Pump Installation
Make sure you are thoroughly trained before you attempt any pump installations.Improper conditions or procedures can cause accidents resulting in property damage and personal injury.
Quick Reference Guide For Trouble Free Operation
PUMP LOCATION•Underneath and as close to thesupply tank as possible.
•Inlet to the pump is very important.
Inlet Piping
•Can use smaller piping on discharge side ofthe pump - watch total distance from pumpto filling point.
Discharge Piping
•A differential by-pass valve must always beinstalled in a pumping system.
•Use a soft seat back checkvalve in discharge lineslonger than 50 feetlocated just past the backto tank by-pass valve.
•The by-pass return lineshould be level or go upto the tank and shouldnot be restricted.
•By-pass valve should bepiped back to the vaporsection of the storagetank and set at least 25psig lower than the pumpinternal relief setting.
