Product Overview
Demanding high pressure dosing is addressed by the DMH 23-16 hydraulic piston diaphragm pump from Grundfos. Pressure relief valve and diaphragm protection ensure operation at elevated pressures.
At 50 Hz, the DMH 23-16 delivers 23 L/h maximum dosing capacity at 16 bar pressure. A 0.09 kW motor with 3 x 415v supply powers the unit. Hydraulic piston diaphragm design provides smooth flow characteristics. Liquid temperature range is -10 to 20°C.
PVDF dosing head construction on the DMH 23-16 incorporates ceramic valve balls and PTFE gaskets. Standard non-return valves are fitted on both connections. Manual stroke adjustment from 5-100% provides 20:1 turndown ratio.
IP65 enclosure with aluminium housing protects the DMH 23-16. G5/8 connections accommodate 4/6, 6/9, 6/12, and 9/12 mm tubing.
