Main features of GB series mechanical diaphragm 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
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
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
