Hydraulic Membrane Pumps

Aug. 8, 2018
These positive displacement hydraulic membrane diaphragm pumps are now available with a field-proven compensating system for recessed filter press feed applications. No VFDs are needed when installed with this option. The pump passively reduces its flow rate with increasing pressure without changing the pump’s fixed stroke rate. Alternatively, the HM pump is also inverter-ready for VFD flow control.
