Definition

Qualsiasi sistema di tenuta costituito da uno o più O-ring elastomerici. Può trattarsi di guarnizioni statiche, in cui non vi è alcun movimento relativo tra le parti (ad esempio una guarnizione O-ring tra il corpo pompa e una staffa), oppure di guarnizioni dinamiche, in cui la tenuta avviene tra un albero in movimento e un alloggiamento fisso (ad esempio le guarnizioni d’albero O-Pro®)

What is an 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).

What is a static o-ring seal?

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.

What is a dynamic o-ring seal?

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