Corken has been serving the liquefied petroleum gas (LPG) industry since the mid-1940s. LPG is a flammable mixture of hydrocarbons gases commonly known as propane and butane. They are used to fuel vehicles, warm homes and businesses, and for cooking purposes all around the world. Over the years, we have developed a wide variety of compression and pumping solutions for autogas filling stations, bulk plant, tank car unloading, and propane delivery truck, propane transport, and agricultural agricultural ammonia transport applications. Each compressor and pump comes with a standard mounting option. If one of our standard mountings does not meet your needs, we will design a custom engineered package for you. For more information on our LPG compression and pumping solutions, click on one of the links below:
Custom Engineered SolutionsWhen one of our standard mountings does not meet your needs, let us customize one for you. Most custom packages are a modification of our standard mountings; however, if your needs do not fit with one of our custom packages, we can start from scratch and build you a mounting or skid from the floor up. Send us your specifications and one of our application engineers will help you design a package that fits your needs. For more information on compressor packaging and pump skids, click here. |
Corken offers a positive displacement sliding-vane, regenerative turbine and side channel design for a wide variety of LPG and agricultural ammonia applications.

ACD CRYO supply a range of reciprocating pumps to meet most requirements. At the bottom end of the scale we have the small RPSA pumps suitable for CO2 and N2O service and we then move to the LIN, LOX, LAR pumps. Here we can supply the conventional horizontal designs or the more recent and extremely reliable vertical P2K30 pump that is now favoured by many air gas companies for cylinder filling. This pump outclasses most of our competitor’s pumps in terms of ease of maintainability and time interval before service is required. We also supply specialist pumps that are used for Hydrogen service or for extremely high pressure oil well service with pressures up to 1200 bar and flow rates of 150 l/min.

ACD CRYO can supply an extensive range of centrifugal pump from road tanker applications to process duties. Besides our fixed speed gearbox pumps we can also supply pumps for use with frequency inverters drive or hydraulic drive thus removing the gearbox from the pump and allowing it to run quietly with more flexibility.
We have developed Frequency Inverter drive pumps specifically to meet the demanding challenges of road tanker applications and are able to supply a pump system complete with frequency inverter, control boxes and flow meter to meet a complex mixture of standard pressure, low pressure and high pressure applications from a single unit.
Our hydraulically driven TOP 260 pump is arguably the quietest hydraulically driven pump available and is capable of meeting the high pressure (35 bar LIN) requirements for laser tank filling. With its totally enclosed oil lubricated bearing housing and cartridge type mechanical seal it is also one of the simplest pumps to maintain.

Horizontal LPG Compressors
Corken’s horizontal compressors offer the largest capacity in liquid transfer. They are used to unload LPG marine barges, which typically are not equipped with on-board transfer equipment. These compressors are also used to recovery both liquid and vapor from the containers after the liquid transfer operation is completed. The horizontal compressors provide a full range of capacities from 600 to 1,725 gpm (137.5 to 391.7 m3/hr) in liquid transfer. 
Advantages
- Modular construction
- Low vibration design
- Heavy duty cylinder design
- Self-lubricating piston and rider rings
- Simple to service
Engineered Packages
Custom-engineered skid-mounted units can be supplied with control panels, wiring, receiver tanks and other special accessories as required.
F291 Compressor
Compressors are extremely versatile for they can be used to transfer liquids between tanks, off-load/load out liquids, recover residual vapor, and evacuate vapors for maintenance purposes. Many LPG piping systems do not provide ideal NPSH conditions for liquid pumps which causes excessive pump maintenance. Since compressors are only exposed to vapors, they are not affected by poor NPSH conditions. Many LPG pressurized tanks such as railcars and buried tanks have top unloading connections. A compressor can be the perfect solution for transferring liquids to and from such tanks.
Advantages
- Threaded and ANSI flanges
- Oil-free design
- Self-lubricating PTFE1 step-cut piston rings
- Packing adjustment screw in most models
- Ductile iron construction
- Positively locked piston
- O-ring head gaskets
- High-efficiency valves
Servicability
Corken compressors are designed to minimize required maintenance and make such maintenance extremely simple. Valve replacement may be accomplished without disturbing the piping and ring replacement may be accomplished by simply removing the head.
Versatility
The same compressor installed for one application can easily be piped to be utilized for other plant applications. An example would be a railcar-unloading, in which the compressor can also be utilized to load and unload trucks.
Truck Compressor Applications
Corken’s LPG compressors have an extended crankshaft option for utilization on trucks with PTO and hydraulic drive systems. The compressor can be utilized for loading/ unloading as well as vapor recovery on trucks.
B166 (3/4″ and 1″) Automatic Dual Purpose, Bypass Valves
Applications
Used with all cylinder filling pumps. (Coro-Flo Models and low flow side channel pumps)
The B166B is a combination bypass and priming valve specifically designed for small cylinder filling type pumps, especially of the regenerative turbine type, such as the Coro-Flo pump series. The vapor elimination system keeps liquefied gas pumps primed to increase system reliability and decrease pump and seal wear. The B166B is a smooth operating bypass with moderate pressure buildup.
T166 (1-1/4″ and 1-1/2″) Pump Flow Control Valve
Applications
Used with large capacity pumps filling various sizes of tanks and bottles such as those used with delivery trucks or multi-spot cylinder-filling plants.
The T166 valve provides smooth-acting flow control. Specifically designed for bypass protection for pumps in the 30–100 GPM (6.8–22.7 m3/hr) range, such as those used on delivery trucks. In contrast to the B177, the T166 valve opens gradually as pressure builds up to modulate the flow, bypassing the excess capacity smoothly and silently back to the supply tank. A continuous internal bleed in this valve assists in eliminating vapors.
B177 (2″ and 2-1/2″) Differential Bypass Valve
Applications
Used in liquefied-gas bulk plant installations for the loading and unloading pumps.
The B177 is a low-pressure buildup valve specifically designed for applications requiring protection for positive displacement pumps in the 50–350 GPM (11.4–79.5 m3/hr) for smooth-acting flow control. To properly function, this valve requires a pressure sensing line for the storage tank. This valve should be applied where horsepower is limited and accuracy set points and flow points are necessary.
