The GEHO® ZPM pump is a crankshaft driven one or two-cylinder double-acting high-pressure piston diaphragm pumps. The unique preformed GEHO® diaphragm separates the pumped slurry from all the pump moving parts. This range of pumps is ideal to handle abrasive and corrosive slurries against high pressures at the lowest possible total cost of ownership. High efficiency and reliability strongly contribute to this objective. The ZPM pump range is developed and manufactured by Weir Minerals Netherlands b.v.
