The all-new Watson-Marlow 520 pumps were designed for the specific needs of process and science. They are fitted as standard with the new 520R pumphead which accepts up to 9.6mm bore tubing for flow rates up to 3.5 liters/min. The 520R continues Watson-Marlow's low-shear, high-reliability pumphead design for high accuracy and long tube life. Sprung stainless-steel rollers, low rotational speeds and a large swept volume make the 520R our gentlest, most powerful pumphead yet. The 520S with manual control and the 520U with remote auto and analog control both provide outstanding performance, long life, reliability and great value. Watson-Marlow's modular design allows a range of pumpheads to be fitted by the user to provide low pulse and multi-channel pumping options.
