The pump also features an optional motor-mounted outlet port with a pressure relief valve to ensure safe exhaust operation. QMB 250 offers a broad selection of accessories to customize the setup and optimize usage. The pump can be fitted with valves, fittings, and electronic pressure controllers to manage system pressure and protect the performance and longevity of the unit. In addition, the integrated EDWARDS Eco design includes a re-circulation feature that prevents contaminated oil from entering the pumping machine and extends service life.
