Stationary Pumps

Z4500: The Z4500 is a four-inch stationary LPG pump designed for transport loading and multiple bobtail loading applications. If you have two or more bulkheads to load bobtails and transports and would like to shorten your fill times, then the Z4500 is the stationary pump for you.

Z3500: The new three-inch Z3500 LPG pump was designed for stationary and foot mounted truck applications. The Z3500 stationary pump has the same locked rotor design used in the Corken Z-Series truck pumps to ensure long pump life and excellent performance. With higher flow rates than other three-inch pumps, the Z3500 retrofits Corken’s and other competitive pumps with little or no change in piping.

Coro-Vane Pumps: The positive displacement, sliding-vane design of the Coro-Vane pump is commonly found in the LPG industry. The Coro-Vane® pump is unique because it can handle small amounts of vapor formed at the pump suction, and the vanes are self-adjusting for extended wear.

Coro-Flo Pumps: The Corken Coro-Flo® pump was specifically designed for LPG, NH3 and other light liquids. The regenerative turbine construction provides smooth continuous flow with trouble-free service for volatile liquids such as LPG.

Side Channel Pumps: The SC-Series multistage side-channel pumps are designed for LPG applications where high-differential pressure is necessary or low NPSH conditions exist. The side channel design provides smooth continuous flow and trouble-free service.

Autogas Pumps: The Autogas regenerative turbine pumps are designed for LPG applications where high differential pressure is required. The Autogas pumps provide the same smooth continuous flow and trouble-free service as the Coro-Flo models only at higher levels of performance.
