Kolbenpumpe

摘要

The invention relates to a reciprocating pump comprising a piston (10) guided in an axially displaceable manner in a pump bore (12) of a pump housing (14). To simplify the manufacture of the piston (10) the invention provides for the piston (10) to be fitted with a supporting ring (64) which is connected to a guide ring (66). By joining the supporting ring (64) and the guide ring (66) the overall length of the reciprocating pump (10) can be reduced.
