High pressure homogenizing pump having removable check valve modules

摘要

A homogenizer includes a homogenizing valve assembly mounted to a pump block. A set of one or more pump chambers is formed in the block and a plunger is positioned in each chamber. Each pump chamber is formed along a substantially horizontal pump axis and extends through the pump block. A removable check valve module comprising a suction valve assembly and a discharge valve assembly is positioned in a bore which intersects each pump chamber. Each valve module is secured in the bore by a retaining pin such that the module can be easily and quickly removed as a single unit.
