Abstract

1. Plunger piston metering pump (1) with a metering piston (2) constructed as plunger piston and with a conveying cylinder, preferably for the metering of an additive liquid into the injection point of a main liquid duct, in particular water duct, with an exchangeable insert part (11), which is subject to wear and which being constructed as pre-assembled unit comprises the metering piston (2) and piston-guiding elements, characterised thereby, that the insert part (11), which is subject to wear, includes the conveying cylinder with piston-centering unit (13) and upper piston-guiding part (16).
