Gorman-Rupp”sRAMPARTS air-driven diaphragm pump is application-proven up to 6 percentsolids. The pump”s patent-pending integrated speed-control system isconstructed with durable, RAMPARTS components for use in real-worldapplications. With its modular construction, it isboth operator and maintenance friendly, allowing for in-place service,and/or field retrofit of either RAMPARTS or competitors’ pumps. Thespeed-control system is designed for intermittent or continuous duties, aswell as variations in temperature, air pressure, or pump speed. Thecontrol system ensures a full displacement stroke every time. It alsooffers independent control of the suction and discharge strokes,allowing the pump to be tuned to the application.
