Product Overview
Higher capacity high pressure dosing is served by the DMH 45-16 hydraulic piston diaphragm pump from Grundfos. Pressure relief valve and diaphragm protection ensure operation at elevated pressures.
The DMH 45-16 provides 45 L/h maximum dosing capacity at 16 bar pressure with 50 Hz operation. A 0.20 kW motor on 3 x 415v supply powers the unit. Hydraulic piston diaphragm design yields smooth flow characteristics. Temperature range spans -10 to 20°C.
PVDF construction with ceramic balls and PTFE gaskets features in the DMH 45-16 dosing head. Standard non-return valves are installed on both connections. Stroke adjustment from 5-100% provides 20:1 turndown ratio.
IP65 enclosure with aluminium housing protects the DMH 45-16. G5/8 connections accept 4/6, 6/9, 6/12, and 9/12 mm tubing.
