Watson-Marlow peristaltic pumps

Watson-Marlow offers the widest range of peristaltic pumps, capable of handling flow from 0.6 μl/min. to 8,000 litre/hour and handling pressures of up to 7 bar (100 psi). With no seals, valves or moving parts in the flow path, the risk of clogging, leaking or contamination is eliminated.  

Accurate and repeatable flow rates

Contamination-free pumping - ideal for shear sensitive fluids, viscous sludges or slurries, and aggresive acids and caustics

Easy to install, operate and maintain

Virtually maintenance-free - no expensive seals, valves, diaphragms or rotors to leak, clog or corrode.
