Product Overview
Chemical industry applications are served by the DMX 115-3 mechanical diaphragm dosing pump from Grundfos. Manual stroke length adjustment from 10-100% yields a 10:1 turndown ratio for dosing rate control.
The DMX 115-3 delivers 115 L/h maximum dosing capacity at 3 bar pressure, operating at 50 Hz with a 0.09 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.
Ceramic valve balls and EPDM gaskets are incorporated in the DMX 115-3 thermoplastic dosing head. Standard non-return valves are fitted on both connections. The PTFE-coated diaphragm handles liquid temperatures from 0 to 40°C.
Aluminium gear housing with IP65 enclosure protects the DMX 115-3. G5/4 connections accommodate 19/27 and 20/25 mm connections.
