Colfax Fluid Handling launches progressive cavity pumps

Colfax Fluid Handling has introduced the Allweiler All-Optflow series of progressive cavity pumps for waste, wastewater treatment and paper manufacturing.


The All-Optiflow progressing cavity pumps offer up to twice the flow of standard pumps for applications up to 6 bar (87 psi) and can move virtually any type of liquid, including fibrous and solid materials, with a viscosity up to 300,000 mm2/sec. Its maximum capacity is 3800 l/min.
Colfax's pumps feature high power density to help reduce energy consumption by up to 15% when compared to standard progressive cavity pumps. Ths shaft diameters are approximately 30% smaller than those found in standard progressing cavity pumps, reducing friction by nearly 50%. The All-Optiflow series features redesigned pumping elements with higher power density, low-friction rotors and shaft seals, and stators with a special surface.
This Allweiler pump series can improve the standardisation 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.
