Micro Water Pump EPDM Rubber Diaphragm

This is a 2-port piston body for small coffee machines in pump-valve systems, a specialized component that complements the fluid control functions of Sealed Fluid Transfer Pumps and Micro Sealed Hydraulic Pumps in compact beverage equipment. As a key part of Precision Piston Assemblies tailored for household and small commercial coffee machines, it features a spire-like design: the top of the piston body is pointed, while the bottom gradually widens or takes a stepped shape. This structure facilitates precise pressing in narrow brewing chambers or portafilters, minimizing dead corners where coffee grounds accumulate. One end is equipped with a slender handle (similar to a "needle" structure) — this handle is used to connect to manual operating levers or mechanical transmission components, enabling easy pressure application or movement stroke control. Its design aligns with the functional precision requirements of Pistons and Reciprocating Pistons in small-scale fluid pressure systems.…
