The characteristics of Variable eccentric mechanism adjustment, gentle pulsation

• various materials and pump head structure optional -PVC, PVDF, 316SS, high viscosity and slurry pump head

• mechanically driven PTFE diaphragm

• material side diaphragm protector, easy to pass through

• three automatic control modes, suitable for various control needs

• manual/electric stroke adjustment is optional

• adjustable stroke 0~100% (automatic/manual)

• the stroke can be adjusted under both static and dynamic conditions

• maximum liquid temperature 40℃*

• steady-state accuracy: ±2% (10%~100%)

• maximum suction: 3m water column *

• maximum suction pressure: 20m water column

• optional dual diaphragm head construction

• recommended maintenance cycle: ≤1.0MPa4000h  0.7 or less MPa8000h, Automatic control mode selection

• electric stroke controller



Receive external control signal, adjust the length of metering pump stroke, Thus changes the metering pump output flow.

G series metering pump chooses HE type. Among them, the GB series can choose ECC explosion-proof type.

• frequency conversion controller

Receive external control signal, adjust the speed of metering pump stroke.

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

Control signal: 4~20mA

• VARIPULSE controller:

Used for GM series metering pump, used for controlling three-phase motor,

Change the stroke frequency, so as to adjust the output flow of metering pump.
