Coro-Flo Turbine Pumps Stationary Applications ®
Designed specifically for LPG... The Corken Coro-Flo® pump was designed for LPG, NH3 and other light liquids. For low-capacity, medium-head pumping, the Coro-Flo pump is the pump of choice. Extremely quiet and free of vibration and pulsation, the Coro-Flo pump provides trouble-free service and long life for volatile liquids such as LPG. The exclusive turbine construction provides smooth continuous flow through the pump case, resulting in higher efficiency and greater capacity and pressure for the same size motor. The one moving part, the impeller, floats on the shaft without ing adjacent surfaces, thus extending pump life.
Heavy-duty, permanently lubricated ball bearings: Ensure precision operation and long service life. Balanced mechanical seal assembly: Easily replaced by removing the cover. High flow inlet and discharge: Provides higher efficiency and greater capacity.
3/4" NPT Connection: For easy installation of by valve system.
Simple to service... The Coro-Flo® pump has been designed for simplicity of inspection and service. The cover can be removed and the impeller and seal serviced without disturbing the piping. The balanced mechanical seal is furnished with its own sleeve, providing extremely reliable service.
Applications... Although the Corken Coro-Flo® pump was originally developed to fill propane cylinders, it has found its way into many other applications, especially where volatile liquid transfer is involved. It is commonly used to feed industrial vaporizing and aerosol filling systems, and to transfer liquefied gases like NH3, CO2, SO2 and refrigerant gases. In process plants, the Coro-Flo pump is used as a boiler feed pump and for handling condensate. Every Corken Coro-Flo® pump is thoroughly inspected and tested to assure its quality and performance. The Coro-Flo pump is listed by Underwriters’ Laboratories, Inc. for use in LP-Gas and anhydrous ammonia service.

Side Channel Pumps Stationary Applications For those LPG applications where high-differential pressure is necessary or low NPSH conditions exist, such as pumping from underground tanks, the SC-Series multistage side channel is the pump of choice. The integral centrifugal and side channel design which characterizes this line provides a new dimension in liquid transfer applications. The SC-Series exceeds expectations in the handling of liquids involving high-differential pressures, low NPSH conditions, and aerated liquids up to 50% gas. Six different sizes, each ranging from one to eight stages, provide solutions for a wide range of pressures, capacities, and liquid transfer requirements. Multiple material and sealing options, enabling it to handle many different liquids, enhance the versatility of the SC-Series. Typical installations where this pump might be found are LPG cylinder filling, vaporizer feeding, pumping from underground storage and bulk filling operations.
Multiple material options for impellers and casing: Ductile iron casing, brass impellers, and Viton® are standard for LPG applications.
Proprietary centrifugal impeller design: Ensures efficient transfer even at low NPSH conditions.
Multistage side channel design delivers higher differential pressures... The Corken SC pump line utilizes an integral centrifugal and side-channel design to create the flow characteristics that make this pump special. The high-differential pressure and self-priming capabilities are results of the multistage side channel design. This feature incorporates one to eight stages of open radial-vane impellers and special modular side channel casings.
Quiet, smooth transfer even at low NPSH... The SC pump’s ability to handle low NPSH applications is attributed to the proprietary centrifugal impeller design near the pump inlet. The SC pump is cylindrical in shape, with liquid flow entering the pump horizontally (parallel with the pump shaft) and exiting vertically through the discharge flange on the top of the pump.
Many sealing options to choose from, including magnetic drive...
Modular construction: Minimizes spare parts requirements.
In a time when leakage control is becoming more and more prevalent, Corken offers a complete range of seal options. The side channel magnetic drive (SCM) sealless multistage pump meets the most stringent environmental regulations. The SCM line retains all of the advantages of the standard SC design along with two additional advantages; there are no seals to maintain and no potential leak paths.

Coro-Vane Pumps Stationary Applications ®
Pump design delivers high pumping efficiencies. The sliding-vane design of the Coro-Vane® pump is commonly found in the LPG industry because its pumping efficiencies remain high throughout the life of the pump. The CoroVane pump is unique because it can handle small amounts of vapor formed at the pump suction, and the vanes are self-adjusting for wear. With these design characteristics, pumping efficiencies remain high throughout the life of the pump.
Built-in relief valve: Preset, no-adjust internal relief valve always assures proper setting.
Pressure gauge connections: Available for both suction and discharge.
Long life & ease of maintenance... The pump housing and rotors are constructed of ductile iron for high strength. The pump design includes removable pump casing liners in all models. Worn liners and vanes can be replaced in minutes. Some models incorporate reversible sideplates which double their service life. Seal maintenance is easy. Simply remove four bolts to remove bearings and seals.
Applications... Typical applications include cylinder filling, loading and unloading of bulk trucks and transport trailers. Some Coro-Vane® pump models come with an internal relief valve for added pump protection, relieving the pressure from the pump discharge back to the suction. All pumps must have an external by valve to comply with NFPA & UL code requirements.
Positive displacement... Coro-Vane® pumps are positive displacement pumps. They produce up to a maximum differential pressure of 125 psig (8.6 bar g). Corken manufactures five sizes of Coro-Vane pumps, ranging from 1 gpm to 350 gpm (0.2 to 79.5 m3/hr) with v-belt and direct-drive mounting options.
Precision-machined sideplates and liners (cam): Maximize pumping capacity and are easily replaced.

Vertical LPG Compressors Stationary Applications Why select a compressor to transfer LPG and NH3? 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.
Why select a Corken compressor? Corken has over 60 years of experience in providing state-of-theart designs to the LPG and NH3 markets. Corken designs meet the most stringent global quality standards, including those of Japan, and the United States. Environmental impact and safety are always considered very seriously at Corken.

Corken currently offers 8" (203.2 mm), 6" (152.4 mm), 5" (127.0 mm), 4" (101.6 mm), 3-1/4" (82.6 mm), and 2-3/4" (69.9 mm) cylinders. These cylinders may be arranged in various combinations of single-, two-, three-, or four-stages. The horizontal compressors are offered in lubricated and non-lubricated designs. Although these compressors are not classified as oil-free, the potential for oil carry-over is minimized.
For stringent environmental requirements... In response to increasingly stringent environmental requirements to reduce emissions of volatile organic compounds and other hazardous gases, Corken offers a purge-pak piston-rod-sealing system for the HG601 series horizontal compressors. While precise leakage rates cannot be guaranteed due to the many complex factors which affect leakage, the purge-pak and rodsealing system substantially reduces potential leakage compared to conventional segmented piston-rod seal configurations. Tests have shown that in many cases, leakage can be reduced below 1 scfh (0.027 m3/hr).
Water-cooled cylinders... To increase the versatility of the horizontal compressor, Corken offers water-cooled cylinders in the 8" (203.2 mm), 6" 152.4 mm), 4" (101.6 mm) and 3-1/4" (82.6 mm) bore sizes. Water-cooled cylinders greatly reduce the operating temperature which increases the valve, piston ring, and seal life in the most difficult applications.

Crankshaft journal, connecting-rod bearings, wrist pins and crossheads: Pressure lubricated by an oil pump with oil filtered by a 10-micron spin-on filter. Thermostatically-controlledcrankcase heater (optional): Assures proper oil viscosity in all weather conditions. Heavy-duty crankcase: A rugged, internally ribbed design, incorporating heavy-duty main bearings and four-bolt connecting rods. Force-feed lubricator (optional): Assures proper lubrication of cylinders and packing when required.
Tanker and Multiple Railcar Unloading and Recovery Available Options Blank valve... Heavy-duty cylinder design: Each cylinder is hydrostatically tested to 1-1/2 times the rated working pressure for maximum strength. MC1002 coating is available on all cylinders, providing longer piston-ring life.
In addition to the flexibility of reconfiguring the stages and number of cylinders, the capacity may be controlled through the blank valve option, which changes the cylinder to single acting.
Variable clearance heads... This option on all cylinder sizes allows for pressure and capacity adjustment while the compressor is operating.
External crankcase oil cooler... Corken compressors can be equipped with a force-feed lubrication system and external oil filter. An optional external oil cooler is available when required to ensure optimal service life.
Materials... The horizontal compressor line offers many optional materials for parts such as gaskets, piston rings, o-rings, pistons and more. This allows the compressor to be used with a variety of gases. The MC1002 corrosion-resistant coating is also available for all parts that come in with the gas.
Engineered packages... Custom-engineered skid-mounted units can be supplied with control s, wiring, pulsation dampeners, receiver tanks and other special accessories as required.
Placement of valves: Makes inspection and maintenance simple.

Coro-Flo Turbine Pumps Stationary Applications ®
Designed specifically for LPG... The Corken Coro-Flo® pump was designed for LPG, NH3 and other light liquids. For low-capacity, medium-head pumping, the Coro-Flo pump is the pump of choice. Extremely quiet and free of vibration and pulsation, the Coro-Flo pump provides trouble-free service and long life for volatile liquids such as LPG. The exclusive turbine construction provides smooth continuous flow through the pump case, resulting in higher efficiency and greater capacity and pressure for the same size motor. The one moving part, the impeller, floats on the shaft without ing adjacent surfaces, thus extending pump life.
Heavy-duty, permanently lubricated ball bearings: Ensure precision operation and long service life. Balanced mechanical seal assembly: Easily replaced by removing the cover. High flow inlet and discharge: Provides higher efficiency and greater capacity.
3/4" NPT Connection: For easy installation of by valve system.
Simple to service... The Coro-Flo® pump has been designed for simplicity of inspection and service. The cover can be removed and the impeller and seal serviced without disturbing the piping. The balanced mechanical seal is furnished with its own sleeve, providing extremely reliable service.
Applications... Although the Corken Coro-Flo® pump was originally developed to fill propane cylinders, it has found its way into many other applications, especially where volatile liquid transfer is involved. It is commonly used to feed industrial vaporizing and aerosol filling systems, and to transfer liquefied gases like NH3, CO2, SO2 and refrigerant gases. In process plants, the Coro-Flo pump is used as a boiler feed pump and for handling condensate. Every Corken Coro-Flo® pump is thoroughly inspected and tested to assure its quality and performance. The Coro-Flo pump is listed by Underwriters’ Laboratories, Inc. for use in LP-Gas and anhydrous ammonia service.

Side Channel Pumps Stationary Applications For those LPG applications where high-differential pressure is necessary or low NPSH conditions exist, such as pumping from underground tanks, the SC-Series multistage side channel is the pump of choice. The integral centrifugal and side channel design which characterizes this line provides a new dimension in liquid transfer applications. The SC-Series exceeds expectations in the handling of liquids involving high-differential pressures, low NPSH conditions, and aerated liquids up to 50% gas. Six different sizes, each ranging from one to eight stages, provide solutions for a wide range of pressures, capacities, and liquid transfer requirements. Multiple material and sealing options, enabling it to handle many different liquids, enhance the versatility of the SC-Series. Typical installations where this pump might be found are LPG cylinder filling, vaporizer feeding, pumping from underground storage and bulk filling operations.
Multiple material options for impellers and casing: Ductile iron casing, brass impellers, and Viton® are standard for LPG applications.
Proprietary centrifugal impeller design: Ensures efficient transfer even at low NPSH conditions.
Multistage side channel design delivers higher differential pressures... The Corken SC pump line utilizes an integral centrifugal and side-channel design to create the flow characteristics that make this pump special. The high-differential pressure and self-priming capabilities are results of the multistage side channel design. This feature incorporates one to eight stages of open radial-vane impellers and special modular side channel casings.
Quiet, smooth transfer even at low NPSH... The SC pump’s ability to handle low NPSH applications is attributed to the proprietary centrifugal impeller design near the pump inlet. The SC pump is cylindrical in shape, with liquid flow entering the pump horizontally (parallel with the pump shaft) and exiting vertically through the discharge flange on the top of the pump.
Many sealing options to choose from, including magnetic drive...
Modular construction: Minimizes spare parts requirements.
In a time when leakage control is becoming more and more prevalent, Corken offers a complete range of seal options. The side channel magnetic drive (SCM) sealless multistage pump meets the most stringent environmental regulations. The SCM line retains all of the advantages of the standard SC design along with two additional advantages; there are no seals to maintain and no potential leak paths.

Coro-Vane Pumps Stationary Applications ®
Pump design delivers high pumping efficiencies. The sliding-vane design of the Coro-Vane® pump is commonly found in the LPG industry because its pumping efficiencies remain high throughout the life of the pump. The CoroVane pump is unique because it can handle small amounts of vapor formed at the pump suction, and the vanes are self-adjusting for wear. With these design characteristics, pumping efficiencies remain high throughout the life of the pump.
Built-in relief valve: Preset, no-adjust internal relief valve always assures proper setting.
Pressure gauge connections: Available for both suction and discharge.
Long life & ease of maintenance... The pump housing and rotors are constructed of ductile iron for high strength. The pump design includes removable pump casing liners in all models. Worn liners and vanes can be replaced in minutes. Some models incorporate reversible sideplates which double their service life. Seal maintenance is easy. Simply remove four bolts to remove bearings and seals.
Applications... Typical applications include cylinder filling, loading and unloading of bulk trucks and transport trailers. Some Coro-Vane® pump models come with an internal relief valve for added pump protection, relieving the pressure from the pump discharge back to the suction. All pumps must have an external by valve to comply with NFPA & UL code requirements.
Positive displacement... Coro-Vane® pumps are positive displacement pumps. They produce up to a maximum differential pressure of 125 psig (8.6 bar g). Corken manufactures five sizes of Coro-Vane pumps, ranging from 1 gpm to 350 gpm (0.2 to 79.5 m3/hr) with v-belt and direct-drive mounting options.
Precision-machined sideplates and liners (cam): Maximize pumping capacity and are easily replaced.

Vertical LPG Compressors Stationary Applications Why select a compressor to transfer LPG and NH3? 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.
Why select a Corken compressor? Corken has over 60 years of experience in providing state-of-theart designs to the LPG and NH3 markets. Corken designs meet the most stringent global quality standards, including those of Japan, and the United States. Environmental impact and safety are always considered very seriously at Corken.

Horizontal LPG Compressors Stationary Applications For high-volume transfer...
Self-lubricating piston and rider rings: Made of PTFE to ensure extended service life.
Corken’s horizontal single-stage compressor is perfect for the terminal requiring transfer of large volumes of LPG (i.e., barge, multiple rail car, etc.). This heavy-duty, balanced-opposed gas compressor offers smooth, quiet operation. The compressor is offered with various sizes of cylinders. Corken currently offers 8" (203.2 mm), 6" (152.4 mm), 5" (127.0 mm), 4" (101.6 mm), 3-1/4" (82.6 mm), and 2-3/4" (69.9 mm) cylinders. These cylinders may be arranged in various combinations of single-, two-, three-, or four-stages. The horizontal compressors are offered in lubricated and non-lubricated designs. Although these compressors are not classified as oil-free, the potential for oil carry-over is minimized.
For stringent environmental requirements... In response to increasingly stringent environmental requirements to reduce emissions of volatile organic compounds and other hazardous gases, Corken offers a purge-pak piston-rod-sealing system for the HG601 series horizontal compressors. While precise leakage rates cannot be guaranteed due to the many complex factors which affect leakage, the purge-pak and rodsealing system substantially reduces potential leakage compared to conventional segmented piston-rod seal configurations. Tests have shown that in many cases, leakage can be reduced below 1 scfh (0.027 m3/hr).
Water-cooled cylinders... To increase the versatility of the horizontal compressor, Corken offers water-cooled cylinders in the 8" (203.2 mm), 6" 152.4 mm), 4" (101.6 mm) and 3-1/4" (82.6 mm) bore sizes. Water-cooled cylinders greatly reduce the operating temperature which increases the valve, piston ring, and seal life in the most difficult applications.

A combination by and priming valve specifically designed for small cylinder-fillingtype pumps, especially of the regenerative turbine type, such as the Corken Coro-Flo® pump series. The patented vapor elimination system keeps liquefied gas pumps primed to increase system reliability and decrease pump and seal wear. The B166B is a smooth operating by with moderate pressure build-up.
ZV200 By Valve Typical Applications: Used for both truck and stationary applications for loading and unloading. A low-pressure build-up by valve designed for applications requiring protection for positive displacement pumps. Specifically designed for protecting pumps with capacities up to 250 gpm (56.8 m3/hr). The continuous internal bleed will assist in the operation of systems with “air” or “electric” operated internal valves.
