Piston Wellpoint Dewatering Pump
The MWI Piston Wellpoint is a reliable piston, self-priming, positive-displacement pump that is made for construction dewatering. Its compact, mobile footprint and integrated sound enclosure makes it your ideal, agile companion when facing tough water pumping challenges in residential neighborhoods or areas where sound must be kept to a minimum. Whether you are using a wellpoint or sock system, the highly-efficient air/water handling capabilities utilizes less fuel while providing less hassles.

Downtime is substantially reduced thanks to the maintenance-on-site design. The piston wellpoint pump produces a pulsating vacuum so wellpoints will not become clogged in service. It only requires a single cylinder engine and does not contain any vacuum pumps or associated oiling systems typically required in other wellpoint pumps. With inexpensive spare parts, low maintenance, and rugged components, this pump costs less than comparable pump systems and can be set up and running in a fraction of the time.
