Watson Marlow 630S Peristaltic Pump

This listing is for the Watson Marlow 630S Peristaltic Pump

The unit is in full working condition and is ready for immediate use

A peristaltic pump moves fluid through a flexible tube by sequentially compressing the tube (like a wave) which pushes the fluid forward. Because only the inner surface of the tube contacts the fluid, the pump mechanism is isolated from the fluid — this is useful for:

Handling corrosive, abrasive or sterile fluids

Avoiding contamination (the pump body doesn’t contact the fluid)

Easy maintenance (replace the tubing rather than the pump’s internal components)

Watson‑Marlow is a well-known maker of such pumps in lab, process, pharmaceutical, chemical, water treatment, and industrial settings.

Typical applications / use cases

Because of the flexibility, purity, and control of peristaltic pumps, the 630S is used in:

Chemical dosing / metering (acid, base, reagents)

Pharmaceutical / biotech processes

Water / wastewater treatment

Food & beverage (for sterile or food-contact fluids)

Laboratory and pilot-scale processing
