Dosing pump for metering and conveying liquid, has electromagnetic drive and displacement unit that is formed as main piston pump, where displacement unit has cylinder, piston, inlet valve and check valve

摘要

The dosing pump (1) has an electromagnetic drive (2) and a displacement unit (3) that is formed as a main piston pump, where the displacement unit has a cylinder (5), a piston (4), an inlet valve (17) and a check valve (9). The cylinder is axially frictionally mounted in a cone (6) of the electromagnetic drive on a side facing an actuator (7). A component (8) is formed as an elastomer-coated part and is made of plastic.
