Product Overview
The Grundfos DMX 27-12 mechanical diaphragm dosing pump is suitable for water treatment applications. Manual stroke length adjustment from 10-100% provides a 10:1 turndown ratio for dosing rate control.
At 50 Hz operation, the DMX 27-12 delivers 27 L/h maximum dosing capacity at 12 bar maximum operating pressure. A 0.09 kW motor with 1 x 240v supply powers this unit. Dosing flow variation is maintained at less than ±1.5% with linearity within ±4% at minimum 1 bar differential pressure across the dosing head. Suction lift during operation is 1 metre.
The DMX 27-12 dosing head incorporates ceramic valve balls and EPDM gaskets with thermoplastic construction. 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 27-12. G5/8 connections with hose adaptor options for 4/6, 6/9, 6/12, and 9/12 mm tubing are provided.
