O-ring Seal

O-ring seals are any seal that consists of one or more elastomeric o-rings. These may be static seals wherein there is no relative motion between parts (i.e. an o-ring seal between a pump casing and bracket) or dynamic seals wherein the seal is created between a moving shaft and a stationary housing (i.e. O-Pro® shaft seals).

O-ring seals that are static are between pump parts where there is no relative motion. This can be between head and casing, casing and bracket, and casing and port connections.

Dynamic o-ring seals are created between the rotating shaft and a stationary housing.
