Hydraulic Diaphragm Metering Pumps - Double Diaphragm Design, 100% Leak-proof Safety Valves And Long Service Life Features

Following are the Main features of Hydraulic Diaphragm Metering Pumps :
Seal without leakage: Liquid is completely isolated by the diaphragm, so diaphragm metering pump have 100% proof of leakage. It is very good for the viscous, poisonous, corrosive liquid handing.
Long service life: The diaphragm is not directly connected with the piston; the diaphragm will be much more long-lived. And also it allow much higher pressure than the mechanical type
Insides safety valve: For measuring accuracy, each hydraulic diaphragm metering pump will be installed with safety valve, air release valve and surge valve, this is also useful for pump safety, absorbing liquid impact.
Double diaphragm: For safety, pump can be in double diaphragm type with an alarm system; it will stop the pump and give an alarm signal, when one diaphragm breaks.
