Mark 3 Unitized Self Priming Pump

Pumps Flowserve

The Durco Mark 3 Unitized Self Priming Pump is a centrifugal pump engineered to draw from liquid sources below ground level or from sources that have no positive pressure to naturally prime the pump. Conveniently located high and dry at ground level, where installation is simple and maintenance is easier and more economical, the Mark 3 Self-Priming pump costs less to buy, install, and maintain than submersible pumps. Its compact design enables it to fit in tight clearance locations, and it can also be mounted on a trailer for movement to various pumping areas, such as for wastewater lagoon service.
