Unlike diaphragm, rotary lobe, and PC pumps, the peristaltic design of the Watson Marlow Bredel hose pumps contains no transferring 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 exchange.
เพรสเชอร์เกจ hose pumps also remove the need for ancillary gear corresponding to dry run safety, seal water flush methods and in-line examine valves. A hose change takes only minutes and may be performed in-situ with out particular instruments or skilled personnel.
The pumped fluid is totally contained in a long-life hose, protecting operation and maintenance personnel and the setting from undesirable spillages or exposure to chemical substances. Flow is totally independent of suction and discharge conditions. ไดอะแฟรม is precision machined to ensure flow stability and pump efficiency in tough fluid handling purposes.
digital pressure gauge achieve flow rates up to 475 GPM, transferring as much as 80% solids in suspension.
