Watson Marlow 505S Peristaltic Pump

Equipped with a 501RL Pumphead.

The 501RL pumphead has two spring-loaded working rollers, which automatically compensate for minor variations in tubing wall thickness, giving extended tube life. 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. It is equipped with a “tool lockable” guard for increased safety. This should be locked shut whilst the pump is in use. The pumphead can be run clockwise for extended tube life, or anti-clockwise to operate against higher pressures.
