The Grundfos DMX 14-10 is a versatile positive displacement diaphragm dosing pump designed for reliable chemical dosing in industrial and process applications. The DMX 221 series combines robust construction with straightforward mechanical capacity adjustment for dependable dosing performance.
The diaphragm is mechanically coupled through a precise gear-eccenter-tappet system to a high-efficiency AC motor. Dosing capacity can be adjusted by varying the stroke length using the stroke adjustment knob, providing an adjustment ratio of 1:10. The DMX 221 design uses double ball valves for capacities up to 50 L/h, supporting reliable dosing performance across this flow range.
This configuration features a PVDF dosing head, long-life PTFE-coated diaphragm and PTFE/composite valve components. With a nominal dosing capacity of 14 L/h, maximum operating pressure of 10 bar and compatibility with liquids up to 400 mPa·s viscosity, the pump provides dependable performance for compatible industrial and chemical dosing applications. This configuration is also prepared for VFD operation, offering additional flexibility where variable-frequency operation is required.
