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 refrigerant gases.

Overview
The DL-/DLD-/DLF-model regenerative turbine pump do not require a coupling guard and baseplate. A direct mount is designed to the exact tolerances of the pump and motor so alignment issues are eliminated and installation is quick and easy.

  • 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 you to use 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
