Watson-Marlow Fluid Technology Group’s Bredel heavy-duty hose pumps are a reliable and easy-to-maintain solution for handling the viscous slurries and grit-filled sludge in wastewater treatment plants. Unlike diaphragm, rotary lobe and PC pumps, the peristaltic design of Bredel hose pumps contains no moving parts that come into contact with the product, and no seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode or replace.
Bredel hose pumps also obviate the need for ancillary equipment such as dry run protection, seal water flush systems and in-line check valves. A simple hose change takes only minutes and can be performed in-situ without special tools or skilled personnel. The low-maintenance peristaltic design offers a low total cost of ownership. As the fluid is safely contained within the hose or tube, operation and maintenance personnel and the environment are protected from unwanted spillages or exposure to chemicals.
Bredel hose pumps are dry-running and self-priming, and allow no slippage, for true positive displacement to provide accurate and repeatable metering. The pumped fluid is completely contained in a long-life hose, protecting operation and maintenance personnel and the environment from unwanted spillages or exposure to chemicals.
