ANALOGIC DOSING PUMPS EONE MA SERIES

Operating principles

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).
