Overview
All of Corken’s regenerative turbine pumps are known as a Coro-Flo®. An F-model turbine pump is a frame mount design and requires a baseplate. A frame mount utilizes a direct drive configuration that runs at motor speed and requires a coupling and coupling guard. With a frame mount design, you have the flexibility to choose from a variety of motor types. This turbine pump is designed for liquefied gases such as propane, butane (LPG), agricultural ammonia, natural gas liquids (NGLs), CO2, SO2, refrigerant gases, and many other many more. FF- & FD-models 060, 075, and 150 produce a higher differential pressure than our standard F model pumps and are commonly used in autogas filling stations.

All of Corken’s regenerative turbine pumps are known as a Coro-Flo®. The C-model turbine pump is a close-coupled design that mounts directly to a Corken supplied C-Face motor so no coupling or special alignment procedures are required. With a close coupled design, installation is quick and easy. C-model turbine pumps are designed for low capacity, medium head pumping applications involving liquefied gases such as LPG (propane & butane), CO2, and refrigerant gases. Since the compact,close coupled design is ideal for tight spaces, the C-model Coro-Flo is the pump of choice for dispensing applications like propane cylinder filling stations. Available with NPT or ANSI flange connections.
When an electric motor drive is not a preferred option, misalignment has been an issue, or you have limited space, the hydraulic drive is a great solution. This option allows for direct mounting of a hydraulic motor and forms a compact alignment. The hydraulic drive option is available with the CP-, CD-, PT-, PZ- and Z-model product groups. The hydraulic drive configuration is designated by the lettter “H” within the model number. The model numbers for our hydraulic drive sliding vane pumps begin with CPH, CDH, PTH, PZH and ZH. The operating specifications for the hydraulic models are the same as the standard CP-, CD-, PT-, PZ- and Z-models. For details on the operating specifications, refer to the pages containing our standard models.
The Z-Series Coro-Vane® pumps, the newest line of sliding vane pumps offered by Corken, are designed with our patented needle roller thrust bearing rated for 4,000 lbs. The needle roller thrust bearings protects the pump against dynamic impact loads imposed on the pump by the drive system. Premature failures due to axial thrust loads are minimized on truck applications. They have O-ring construction throughout and are rated for 400 psi (28.6 bar) working pressure. Since the Z-models sliding vane pumps are used primarily in LPG (propane & butane) and agricultural ammonia applications, the non-adjustable internal relief valve is pre-set at the factory.
The SC-model side channel pump is a mechanically sealed design and is the standard seal option for propane, butane, and agricultural ammonia service. There are three mechanical seal options (single unbalanced, single balanced, and double balanced) and two material options for the seal face and seal seat. The side channel pump is a self-priming design so it is ideal for applications with a low net positive suction head (NPSH) such as pumping from a small underground tank. Additionally, the multi-stage configuration enables the side channel pump to reach higher than normal differential pressures. The feature makes it a great fit for high different applications like propane carousel cylinder filling station, aerosol filling stations, vaporizer feed, selective catalytic reduction (SCR) applications.
Corken’s regenerative turbine pump is known as a Coro-Flo® and has a strong reputation in the LPG industry for being a long lasting pump. The free-floating impeller minimized wear and delivers years of trouble free service. The Coro-Flo turbine pump is a continuous duty pump and is an excellent choice for lower flows and moderate to high differential pressures. The liquid is circulated between the teeth of an impeller that rotates between the pump casing and head. Since the Coro-Flo is designed with a free-floating impeller, there is no metal-to-metal contact so maintenance requirements are minimized.
Corken’s positive displacement sliding vane pump, known as a Coro-Vane®, is an excellent choice for propane, butane, and agricultural ammonia applications. The self-adjusting sliding vanes improve the pumping efficiency and help extend the life of the pump. On the standard LPG and Z-model pumps, the cam and sideplates are replaceable. The rotor, cam, sideplates, seals, and bearings are easily replaced by simply removing the pump cover. All of our propane, butane, and agricultural ammonia sliding vane pumps are equipped with a non-adjustable internal relief valve that is pre-set at the factory.
