The DJ-W mechanical diaphragm metering pump integrates sophisticated mechanical structure with diaphragm technology. Driven by mechanical force, it enables precise flow regulation. The durable diaphragm material isolates the medium from the pump body to prevent corrosion. With simple operation and stable performance, it is suitable for quantitative liquid delivery in various industries, such as chemical liquid preparation and sewage treatment reagent dosing.

Work Principle
This series features mechanical diaphragm metering pumps driven by motor via worm gear, suitable for low-pressure fluid metering.
Using a flexible diaphragm instead of a piston, it reciprocates to change chamber volume, sucking/discharging liquid via inlet/outlet valves.
Flow is steplessly adjustable (0-99.9%) for process needs, delivering non-solid corrosive/non-corrosive liquids. Pump heads offer wetted materials: PPH, PTFE, PVC, PVDF, RPP, SS304, 316, 316L.
