Sliding Vane Pumps for LPG & Ammonia

Standard Model Sliding Vane Pump Overview

Corken's standard model LPG sliding vane pumps are know as a Coro-Vane and are used for propane, butane, and agricultural ammonia. They are rated for a maximum working pressure of 400 psi (27.6 bar) and have O-ring construction throughout. The internal relief valve is pre-set at the factory and is not adjustable. They are available with one standard mechanical seal approved for propane, butane and agricultural ammonia. Applications include bulk pump transfer, propane delivery truck and transport. Available in 2” and 3” sizes.
