Colfax Fluid Handling has introduced the Allweiler All-Optflow series of progressing cavity pumps. Applications include waste, wastewater treatment and paper manufacturing. The progressing cavity pumps offer up to twice the flow of standard pumps for applications up to 6 bar 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% when compared to standard progressive cavity pumps. Shaft diameters are approximately 30% smaller than those found in standard progressing cavity pumps, reducing friction by nearly 50%. 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.
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.
PCN Europe’s March issue features an Industry Special covering issues concerning the Environment, we look at the role heat management plays in the world’s largest CO2 test facility, in another one we discover a zero liquid discharge treatment process for waste water. Our Product Focus on Measurement Technology includes among others an application story showing how predication and performance monitoring on a oil & gas platform enables onshore personnel to monitor essential equipment. In our technical article we look at ways to eliminate mechanical issues in differential pressure systems. At this time of the year we are looking forward to the trade show season, especially at Hannover Messe, the leading industrial trade show. This edition also presents you with many other application stories and product news from all areas of the processing industries, enhanced with datasheets and videos.
