Watson-Marlow Fluid Technology Group (WMFTG) has revealed its new Bredel heavy-duty hose pump - 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. Only Bredel industrial hose pumps provide this level of engineering expertise for their drives.
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. Flow is entirely independent of suction and discharge conditions. Every Bredel hose is precision machined to ensure flow stability and pump performance in tough fluid handling applications.
These industrial pumps achieve flow rates up to 475 GPM, transferring up to 80% solids in suspension.
