ANALOGUE METERING PUMPS SERIES MULTIFLOW MA
Principle of operation
The metering pump operates by means of a PTFE (teflon®) diaphragm mounted on the piston of an electromagnet. When
the piston of the electromagnet is attracted, it creates pressure on the pump body thus ejecting liquid from the supply valve.
When the electric pulse is finished, a spring brings the piston back to its initial position flowing liquid through the suction valve.
The pump needs no lubrication and little maintenance thanks to its easy use. The materials used to build the pump make it fit
for dispensing chemically aggressive liquids. The metering pump has been designed for flow rates from 4 to 35 L/h and
pressures from 0 to 10 bar.
