Featuring mechanical and hydraulic diaphragm designs, this line of diaphragm pump offers zero-leakage transport with patented double-PTFE diaphragm assemblies and real-time rupture monitoring, ensuring safe handling of corrosive, viscous, volatile, flammable and toxic liquids. These pumps are ideal for chemical processing, petrochemical injection, wastewater treatment, oilfield polymer/water solid-liquid separation feed, and high pressure cleaning applications requiring leak-free operation with high metering accuracy (±0.5% to ±2%).

Flow range: 10 L/h for DP-series; up to 11900 L/h for double-headed series

Max discharge pressure: 1.2 MPa for DP-series mechanical diaphragm pumps. High pressure double-headed models available up to 11000 L/h with corresponding pressure ratings
