The self-priming peristaltic pump of Watson Marlow type 502S is suitable for pumping liquids without the risk of damaging the pump.

The 501RL is set during manufacture to accept tubing with wall thicknesses of between 1.6mm and 2.0mm, and internal diameters of up to 8.0mm. The 501RL pump head is equipped with a "tool lockable" guard for increased safety, this should be locked shut whilst the pump is in use. 

A major feature of the 501RL pump head is the ability to run the pump head clockwise for extended tube life, or counterclockwise to operate against higher pressures.

This pump is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.
