The Durco Mark 3 Self Priming pump is designed to draw liquid from sources below ground level or with no positive pressure to naturally prime the pump. Its compact design enables it to fit in tight clearance locations. It can be easily mounted on a trailer for movement to various pumping locations such as waste water lagoons. The Durco Mark 3 self priming pump costs less to buy, install and maintain than submersible pumps.
The Self Priming pump is available in close coupled form or as magnetically driven configurations.

Features & Benefits
Unitized one piece casing has a large priming chamber, air separator and volute in one integral component, keeping components to a minimum.
Front vane open impeller delivers high efficiency performance, provides low NPSHR and offers good solids handling.
Run Dry capability allows for minimum supervision.
Reflux Priming Principle
The pump operate on the reflux principle using liquid recirculation to prime the pump. The pressure differential between the aerated liquid at the impeller and the non-aerated liquid in the priming chamber creates a vacuum that pulls the liquid up the pipe.
This principle eliminates the need for both internal valves and external priming devices or foot valves.
