The Watson-Marlow 624S is a heavy-duty IP55 wash-down peristaltic pump designed for demanding laboratory, pilot plant, and industrial process applications. Compared to the 620U, the 624S is built with a sealed wash-down enclosure, making it well suited for environments where frequent cleaning or exposure to moisture occurs.

The 624S combines a digitally controlled brushless DC motor with a rugged IP55-rated enclosure to deliver precise, repeatable fluid handling. Like all Watson-Marlow peristaltic pumps, the fluid contacts only the tubing, eliminating the risk of pump contamination and making it ideal for sterile, corrosive, abrasive, or shear-sensitive fluids.

The pump features precise speed control, reversible flow, self-priming capability, and can safely run dry without damage. This unit is in very nice condition and is being offered at a competitive price.  It is also being sold with a 60-day warranty.
