Product Overview
The Grundfos DMH 4.9-16 PTFE Hydraulic Diaphragm Dosing Pump is a robust industrial dosing pump designed for accurate chemical injection in demanding water treatment, process engineering, industrial dosing and chemical handling applications.
As part of the Grundfos DMH hydraulic diaphragm range, this model uses an external motor with a hydraulically driven diaphragm for strong, reliable dosing performance. The dosing capacity is adjusted manually by changing the stroke length using the front-mounted stroke adjustment knob.
The DMH range is suited to applications where a heavy-duty hydraulic diaphragm dosing pump is preferred for reliable metering under higher pressure conditions. This model is rated for low-flow, high-pressure dosing duties and is built with a robust aluminium pump housing.
This version features a PVDF dosing head, PTFE valve gasket and ceramic valve ball, making it suitable for selected chemical dosing applications, subject to chemical compatibility.
