Product Overview
High pressure dosing with substantial flow capacity is served by the DMH 291-10 hydraulic piston diaphragm pump. Grundfos designed this unit with pressure relief valve and diaphragm protection for high pressure operation.
The DMH 291-10 provides 291 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 291-10 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 291-10. G5/4 connections accommodate 19/27 and 20/25 mm connections.
FEATURES
- Manual stroke length control with 20:1 turndown ratio from 5-100% adjustment
