The Grundfos DMX 82-5D is a versatile dual-head positive displacement diaphragm dosing pump designed for reliable chemical dosing in demanding industrial and process applications. Featuring two PVC dosing heads, robust aluminium construction and mechanically coupled diaphragm technology, the pump provides dependable dosing performance with straightforward manual capacity adjustment.
The diaphragms are 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 dual-head configuration supports chemical metering through two dosing heads, while the single ball valve design and durable construction provide reliable operation in industrial process environments.
This configuration features two PVC dosing heads, long-life PTFE-coated diaphragms, ceramic Al₂O₃ valve balls, PTFE/composite valve seats and FKM/rubber valve gaskets. With a specified nominal dosing capacity of 82 L/h at 50 Hz, maximum operating pressure of 5 bar and compatibility with liquids up to 500 mPa·s viscosity, the pump is suitable for compatible chemical dosing and industrial process applications.
