Product Overview
High capacity chemical industry dosing is served by the DMX 525-3 mechanical diaphragm pump from Grundfos. Manual stroke length adjustment from 10-100% yields a 10:1 turndown ratio for dosing rate control.
The DMX 525-3 delivers 525 L/h maximum dosing capacity at 3 bar pressure, operating at 50 Hz with a 0.40 kW motor on 3 x 415v supply. Dosing flow variation is maintained at less than ±1.5% with linearity within ±4% at minimum 1 bar differential pressure. Suction lift during operation is 1 metre.
Glass valve balls and FKM gaskets feature in the DMX 525-3 thermoplastic dosing head. Standard non-return valves are fitted on both connections. The PTFE-coated diaphragm handles liquid temperatures from 0 to 40°C.
IP65-rated aluminium housing encloses the DMX 525-3. 40 mm connections accommodate high flow requirements.
