Colfax debuts new series of progressing cavity pumps

Colfax Fluid Handling recently introduced its Allweiler All-Optiflow series of progressing cavity pumps for use in waste, wastewater treatment and paper manufacturing applications.

The All-Optiflow progressing cavity pumps provide twice the flow of standard pumps for applications up to 87 psi. They can efficiently move almost any type of liquid including fibrous and solid materials. The pumps include several features that reduce maintenance costs including:

  • High power density that helps reduce energy consumption by up to 15 percent compared to standard progressive cavity pumps.
  • Shaft diameters that are about 30 percent smaller than its standard competitors, reducing friction by 50 percent.
  • The use of low wear materials that extend the pump's life.

This Allweiler pump series is designed to optimize the standardization of structural components, such as a patented stub shaft connection and a lifetime-lubricated joint, allowing operators to move most liquids economically. The stator surface is honeycombed and works in tandem with the patented “sharkskin” rotor surface. This should provide a lower starting and operating torque, allowing the pump to operate at higher efficiency than normal and providing stable performance curves throughout operation.
