Abstract
Official abstract text for this publication.
A reciprocating pump assembly for dispensing liquids is provided. The pump assembly comprises a pump housing providing an interior compartment and being provided with an inlet for providing a liquid to be dispensed, and an outlet for dispensing the liquid. The assembly further comprises a piston being movably mounted within the interior compartment of the pump housing and comprising ferromagnetic material. The assembly comprises a magnetic actuator for generating a linearly moving magnetic field acting on the piston. The magnetic actuator comprises a permanent magnet arranged to be moved in linear directions, whereby the piston is moved in the pump housing between a resting position and an actuated position under influence of the linearly moving magnetic field.
