Main features of GM type mechanical diaphragm metering pump

drive end

Variable eccentric mechanism adjustment ensures smooth changes in flow pulsation

Enhanced structural design, suitable for harsh operating environments

Wear resistant ball bearings for more stable operation

Oil bath lubrication, long working life of driving components

Flow can be adjusted in both shutdown and operation modes, with options for manual, electric, or variable frequency adjustment

liquid end

Mechanical driven diaphragm, without diaphragm protection plate on the material side, facilitating material passage

PVC、PVDF、316SS、 High viscosity, slurry and other pump head materials, suitable for various materials

Self cleaning one-way valve structure

Control method of GM type mechanical diaphragm metering pump

Electric stroke controller, accepts external control signals, adjusts stroke length

Power supply: 220V/50Hz single-phase

Input signal: 4-20mA analog signal

Output signal: 4-20mA/1-5V analog signal, for recording display and control system use
