Overview
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.
