Product Overview
Large flow high pressure dosing is addressed by the DMH 403-10 hydraulic piston diaphragm pump from Grundfos. Pressure relief valve and diaphragm protection ensure elevated pressure operation.
The DMH 403-10 provides 403 L/h maximum dosing capacity at 10 bar pressure with 50 Hz operation. A 0.60 kW motor on 3 x 415v supply powers the unit. Hydraulic piston diaphragm design yields smooth flow characteristics. Temperature range spans 0 to 40°C.
PVC construction with ceramic balls and FKM gaskets features in the DMH 403-10 dosing head. Standard non-return valves are installed on both connections. Stroke adjustment from 5-100% provides 20:1 turndown ratio.
IP55 enclosure with aluminium housing protects the DMH 403-10. G5/4 connections accommodate 19/27 and 20/25 mm connections.
