High Performance
mRoy MRB Series

The mROY® series model B metering pump is controlled-volume, hydraulically-actuated diaphragm pump that is designed for consistent chemical delivery. Its compact design contains a plunger that reciprocates at a fixed stroke, displacing a fixed volume of hydraulic fluid and thereby actuating a flexible, chemically inert PTFE diaphragm to create the pumping action. Designed to meet global industry standards, model B provides accurate dosing of a broad spectrum of fluids. Like all mROY® metering pumps, model B is built to run continually all year long with preventative maintenance, leading to decades of consistent performance.
