Launched at this month’s Hannover Fair (April 24–28), the hydraulic diaphragm pump Hydro/ 4 (photo) supplements this company’s Hydro/ 2 and Hydro/ 3 types, thereby extending the application range to higher capacities. The pump covers the capacity range from 130 to 1,680 L/h at 7 to 25 bars absolute. The Hydro/ 4 is equipped with a polytetrafluoroethylene (PTFE) multi-layer metering diaphragm. The multi-layer diaphragm ensures safe and leakage-free metering. With material options including stainless steel, polyvinylidene difluoride (PVDF) and Hastelloy C, the Hydro/ 4 can be used universally in numerous applications. As standard, all pump types are equipped with a fixed-setting pressure-relief valve that is integrated into the hydraulics and a multi-layer diaphragm with a diaphragm-rupture warning system. The reproducibility of the metering is better than±1% in the stroke length range of 20 to 100%. — ProMinent GmbH, Heidelberg, Germany
