Colfax Fluid Handling has introduced the Allweiler All-Optiflow series of progressing cavity pumps. Applications include waste, wastewater treatment and paper manufacturing.

Colfax Fluid Handling, a global leader in fluid-handling solutions for critical applications, is a business of Colfax Corporation. All-Optiflow progressing cavity pumps offer up to twice the flow of standard pumps for applications up to 6 bar (87 psi) and move virtually any type of liquid, including fibrous and solid materials efficiently and reliably.

The pumps feature high power density to help reduce energy consumption by up to 15 per cent when compared to standard progressive cavity pumps. Shaft diameters are approximately 30 per cent smaller than those found in standard progressing cavity pumps, reducing friction by nearly 50 per cent. This, combined with the application of low-wear materials, provides the potential for reduced maintenance costs. The All-Optiflow series employs a variety of innovative design details designed to reduce energy consumption as well as costs for maintenance and spare parts. Examples include redesigned pumping elements with higher power density, low-friction rotors and shaft seals, and stators with a special surface.
