For pumping harsh fluids nothing beats a peristaltic pump; and when it comes to peristaltic pumps, there's none better than Watson-Marlow Bredel. Ideal pumps for metering and transfer, peristaltic pumps, which are positive displacement pumps, cost less in maintenance and minimize production interruption. And our pumps come with a comprehensive 5 year warranty to demonstrate our pumps' reliability.

The Right Pump for your Process

Unbeatable turndown With a 3600:1 control ratio and over a million:1 flow range, one Watson-Marlow Bredel pump can do the work of several lobe or diaphragm pumps. They handle a range of flow rates unmatched in the pump industry.

Vapor lock eliminated When pumping mixed phase liquids like sodium hypochlorite, lobe and diaphragm pumps can vapor lock when the gas enters the pump chamber. Watson-Marlow Bredel pumps handle the gas as easily as liquid, eliminating the risk of vapor lock.

Chemical resistance Inside and out, Watson-Marlow Bredel pumps stand up to today's most aggressive chemicals. NEMA 4X washdown enclosures ensure long pump life even in the toughest industrial environments. In addition, our wide range of tube element materials guarantee chemical compatibility with your fluid.

Confident controllability Watson-Marlow Bredel pumps integrate seamlessly into your process control system. The pump is self contained and easily configurable; there is no need for separatevariable frequency drives or complex control devices. With built in manual, analog and digital control features, our pumps have the I/O capabilities to meet your process control and monitoring needs.

Self-priming and dry-running It is not always possible to position a pump in the ideal location and often self-priming and dry-running performance is required. These conditions will cause wear in traditional pumps, resulting in loss of performance and premature failure. Watson-Marlow Bredel pumps can dry prime up to 30 feet and run dry indefinitely.

Unmatched accuracy Using microprocessor controlled brushless DC drive technology, Watson-Marlow Bredel pumps meter within ± 0.5% accuracy, regardless of fluid viscosity changes ensuring economical use of expensive chemicals, correct system performance and finished product quality.

Lowest life cycle cost Leakage, clogging or blockage of pumps designed with seals, valves, lobes, rotors, pistons or vanes can be a regular occurrence and expensive to repair. Watson-Marlow Bredel pumps contain the fluid in a low cost tube element, that takes only minutes to replace. We also help save on capital and maintenance cost by not requiring ancillary equipment.
