Product Overview
The Grundfos DMX 16-12 EPDM Mechanical Diaphragm Dosing Pump is a robust motor-driven dosing pump designed for reliable chemical injection in water treatment, fertigation, industrial dosing, process water and chemical handling applications.
As part of the Grundfos DMX mechanical dosing pump range, this model uses an external AC motor with a mechanically driven diaphragm. Dosing output is adjusted by changing the stroke length using the front-mounted adjustment knob, making it a practical option for installations requiring simple, dependable manual capacity control.
The DMX 16-12 is designed for industrial-duty operation with a chemically resistant plastic enclosure, long-life PTFE-coated diaphragm and ball valve design for accurate dosing performance. It is suited to applications where a mechanical dosing pump is preferred over a digital control pump.
This model features a PVC dosing head, EPDM valve gasket and ceramic valve ball, making it suitable for a range of chemical dosing applications, subject to chemical compatibility.
