Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to

clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the

pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic

pumps can operate dry without risk.

Easy to install, simple to operate and inexpensive to maintain, peristaltic pumps are ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. Suitable for metering, dosing and dispensing applications.
