Main performance parameters of GM series mechanical diaphragm metering pump

●Single head maximum flow: 500L/h

●Maximum discharge pressure: 12bar

●The adjustment ratio is 10:1 and the steady-state accuracy is 2%

●The suction lifting height can reach 3M water column

●The maximum inlet pressure is 2 bar

●The maximum allowable temperature of material is 40C

Main features of GM series mechanical diaphragm metering pump

Drive end

●Adjustable eccentric mechanism to ensure smooth flow fluctuation

●Enhanced structure design, suitable for harsh operating environment

●Wear resistant ball bearing makes the work more stable

●Oil bath lubrication, long working life of driving parts

●The flow can be adjusted in the state of shutdown or operation, and the adjustment mode can be manual, electric or frequency conversion

Hydraulic end

●Mechanical drive diaphragm, material side without diaphragm plate, easy for material through

●PVC、 PVDF. 316SS. High viscosity, slurry and other pump head materials, suitable for all kinds of materials

●Structure of self cleaning check valve

Main applications

●Municipal, industrial water and wastewater, swimming pool and other water treatment processes

Control mode

◆The electric stroke controller receives the external control signal and adjusts the stroke length

●Power supply: 220 V - 50 Hz - single phase

●Input signal: 4-20mA analog signal

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

◆Frequency conversion controller, receiving external control signal, adjusting stroke speed

●Power supply: 220 V-50 Hz single phase / 380-50 Hz three phase

●Input signal: 4-20mA analog signal

◆The motor controller controls the three-phase motor in "on / off" mode to adjust the output flow

●Power supply: 200 - 240V / 50 / 60Hz / single phase

●Control mode: can accept 4-20mA analog signal, external pulse signal or manual adjustment
