ANALOGIC DOSING PUMPS EONE MA SERIES
Operating princip les
Dosing pump operation is ensured by a PTFE (teflon®) membrane mounted on the piston of an electromagnet. When the
piston of the electromagnet is attracted, pressure is produced in the pump head and liquid is ejected from the discharge valve.
Once the electrical impulse has terminated a spring brings the piston back to its original position and liquid is called in through the
suction valve. Due to this simple operation of the pump, no lubrication is needed and maintenance is reduced to nearly zero. The
materials used to manufacture the pump make it fit for use even with particularly aggressive liquids. The dosing pump has been
designed for flow rates starting from 1 to 30 l/h and pressures from 4 to 20 bar (depending on pump type).
