2.0 – BT MA/AD SERIES ANALOGICAL DOSING PUMPS
2.1 – 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 body and liquid is ejected from the outlet
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 0 to 80 l/h and pressures from
0 to 15 bars (depending on pump type).
