Watson-Marlow 620S Peristaltic Pump – Used This Watson-Marlow 620S peristaltic pump was previously used for dosing mixed polymer in trial units. The pump is in working condition. Note: The pump head requires a new set of rollers, as the current rollers have worn out tubing within approximately two weeks of use. Sold as seen, no warranty, and returns are not accepted. Ideal for experienced users who can refurbish or replace pump head components.
