Product Overview
Water treatment applications requiring higher flow rates are served by the DMX 321-6 mechanical diaphragm dosing pump from Grundfos. Manual stroke length adjustment from 10-100% gives a 10:1 turndown ratio for dosing rate control.
The DMX 321-6 delivers 321 L/h maximum dosing capacity at 6 bar pressure, operating at 50 Hz with a 0.40 kW motor on 1 x 240v supply. Dosing flow variation is maintained at less than ±1.5% with linearity within ±4% at minimum 1 bar differential pressure. Suction lift during operation is 2 metres.
Ceramic valve balls and EPDM gaskets are incorporated in the DMX 321-6 thermoplastic dosing head. 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 321-6. G5/4 connections accommodate 19/27 and 20/25 mm connections.

What maximum flow rate in liters per minute does this automated dosing pump output?
Chemical transfer across processing loops relies on the DMX 321-6 discharging a peak delivery flow rate of approximately 5.35 L/Min (321.0 L/h) via G5/4.
What robust aluminium casing and wetted diaphragm material construction protect this chemical unit?
Processing industrial reagents without leakage, the Grundfos DMX 321-6 combines aluminium and PVC with EPDM wetted architecture with durable chemical gaskets.
In facility electrical circuits, what motor kilowatt power and supply voltage run this pump?
Electrical energization of the DMX-321-6 utilizes 240 V supplying an industrial drive rated at 0.4 kW (400 W).
Under industrial process conditions, what working pressure in bar and fluid temperature limits apply?
Dosing service guidelines allow the Grundfos DMX 321 6 to operate at pressures up to 6 bar with chemical temperatures reaching up to 40°C.
How high in vertical head elevation can this chemical dosing unit propel solutions?
Hydraulic pressure capability engineered into the DMX_321_6 establishes a maximum dynamic head of approximately 61.2 m.
