Metering pump hydraulic pump Hydro/ 4

with electric motorPTFEmodular

The Hydro/ 4 is an extremely robust hydraulic diaphragm metering pump, which meets the most exacting safety requirements – it is equipped as standard with a pressure relief valve and PTFE multi-layer diaphragm with diaphragm rupture warning system. Its modular construction offers extremely good flexibility in terms of applications. For flexible metering with excellent process reliability in the medium pressure range. The Hydro/ 4 hydraulic diaphragm metering pump (HP4a), together with the Hydro/ 2 and Hydro/ 3 pumps, represents an integrated product range with stroke lengths of 15 and/or 20 mm. This covers the capacity range from 3 to 1,450 l/h at 100 – 7 bar. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification. The Hydro product range is designed to comply with API 675 among others. Your benefits Excellent process safety and reliability: PTFE multi-layer diaphragm with integral diaphragm rupture warning system Integral hydraulic relief valve Metering reproducibility is better than ± 1% in the 20-100% stroke volume range under defined conditions and with proper installation. Excellent flexibility: The modular construction with single and double head versions permits a wide range of applications, with the double head designs being operated in push-pull mode It is possible to combine up to 5 metering units, even with different pump capacities, in multiple pump systems 5 different gear ratios are available
