Main performance parameters of GB series mechanical diaphragm pump

● maximum flow of single head: 1800l / h

● maximum discharge pressure: 12bar

● regulation ratio 10:1, steady-state accuracy 2%

● suction lifting height up to 3m water column

● the maximum inlet pressure is 2 bar

● the maximum allowable material temperature is 40C

Main features of GB series mechanical diaphragm pump

Drive end

● variable eccentric mechanism adjustment to ensure smooth flow pulsation

● enhanced structural design, suitable for harsh operating environment

● wear resistant ball bearing makes the work more stable

● oil bath lubrication, long service life of driving parts

● the flow can be adjusted under 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: 220V-50HZ single phase

● input signal: 4-20mA analog signal

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

◆ variable frequency controller, which receives external control signals and adjusts stroke speed

● power supply: 220v-50hz-single phase / 380-50hz-three phase

● input signal: 4-20mA analog signal

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

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

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

Hydraulic end

● the diaphragm is mechanically driven, and there is no diaphragm protection plate on the material side to facilitate the passage of materials

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

● self cleaning check valve structure

Main application

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