Diaphragm pump
 

Diaphragm pump is a volume pump The max.
discharge pressure of the plunger pump ups to 50MPa.
The diaphragm pump is provided with the alarm for diaphragm rupture to avoid media leakage.
Capacity:8-4000L/h
Discharge pressure: ≤50MPa
Handled medium temperature:-60℃~400℃
Viscosity: ≤6000mm2/s
Precision metering.
The capacity can be infinitely adjusted from 0 to 100% stroke length.
The metering accuracy should not be less than ±1% at the rated condition and maximum relative stroke length.
The motor is set vertically, compact construction, place-saving
