Unlike diaphragm, rotary lobe, and PC pumps, the peristaltic design of the Watson Marlow Bredel hose pumps contains no moving parts that come into contact with the product. It has no seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode or replace.
Bredel hose pumps also eliminate the need for ancillary equipment such as dry run protection, seal water flush systems and in-line check valves. A hose change takes only minutes and can be performed in-situ without special tools or skilled personnel.
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. The 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.
