Coro-Flo® Industrial Turbine Pumps

Corken’s regenerative turbine industrial pumps are continuous duty and ideal for low capacity applications with moderate to high differential pressures. The liquid is circulated between the teeth of an impeller rotating between the pump casing and head. Since the impeller is free-floating, there is no metal-to-metal contact so the pump is virtually maintenance free. There are several models supporting a wide range of differential pressures and capacities.

Even though Corken’s turbine pumps were originally developed to fill propane cylinders, they have found their way into applications involving volatile liquid transfer. Commonly applications vaporizer feed, aerosol propellant, cylinder filling, and dispenser applications. Suitable for light liquids such as gasoline, solvents, and light oils and liquefied gases such as ammonia, carbon dioxide, sulfur dioxide, propane, butane, and refrigerants.

DL, DLD & DLF-Model Turbine Pumps

The DL, DLD, and DLF-model regenerative turbine pump is a direct mount made for a standard, two pole C-Face motor with a 8.5″ rabbit diameter. A 8.5″ rabbit diameter fits 182TC, 184TC, 213TC and 215TC motor frames. The advantage of a direct mount is no coupling guard, baseplate, or special alignment procedures are required for installation. Connections include NPT, Class 300 RF, and DIN.

Specifications
  • Available in several models
  • Single-stage pump
  • A direct mount design utilizes a special bracket that accepts a standard two-pole motor with a 8.5″ rabbit diameter
  • Mounting bracket supports both the pump and motor so they can be coupled directly
  • The DL mount (DL-Model) allows for a larger horsepower motors
  • Direct mount accepts 3 to 10 hp motors
  • Fits 182TC, 184TC, 213TC and 215TC motor frames
  • Mechanically sealed with silicon carbide seal seat Available with NPT or Class 300 RF flange connections
