Corken's Coro-Flo® regenerative turbine pump has a strong reputation for being a long lasting pump. The free-floating impeller minimizes wear and delivers years of trouble-free service. The Coro-Flo turbine pump is continuous duty and an excellent choice for low flows and moderate to high differential pressures. The liquid is circulated between the teeth of an impeller as it rotates between the pump casing and head. Since the impeller is free floating, there's no metal-to-metal contact so the pump is virtually maintenance free. Corken offer several models of regenerative turbine pumps with a wide range of differential pressures and capacities.

Suitable for LPG (propane & butane), agricultural ammonia, and numerous other liquefied gases.

HDP Turbine Pump
Packages

  • Ideal for high differential pressure (HDP) applications
  • Packages available with frame mount (FF-Model) and direct mount (DLF-Model) only
  • An optional variable frequency drive (VFD) is available for single phase applications
  • NOTE: Three phase electrical sources do not require the optional VFD

Overview
In high differential pressure applications (HDP), the installation site can have a single or three phase electrical source. Single phase electrical sources require a variable frequency drive (VFD) to help drive the larger motors required for HDP applications. Conversely, a three phase power source is sufficient for operating the larger horsepower motors so a VFD is not required. With a three phase power source, Corken's standard HDP package (pump, motor, bypass valve, and baseplate only) is all that is needed for HDP applications. A three phase electrical source provides enough power to build 125 to 250 psi (8.6 to 17.2 bar) of differential pressure.

Features of a Variable Frequency Drive (VFD) (NOTE: Required for a single phase electrical source)
  • Easily converts a single phase source to three phase service
  • Slow start-up feature eliminates flow surges
  • Variable motor speed capability maximizes pump performance
  • Includes motor overload protection to minimize potential damage
  • Shipped pre-programmed at 60 Hz with 4 second ramp-up speed
  • Magnetic starter is not required so installation costs are minimized
  • A standard remote switch is available
