The sealing element (18) having an inner sealing lip (48) is sealably captured within the inner circumferential slot (42) formed between the sealing body (12) and the end flange (17).
The gasket (2) is further provided with a sealing lip (15) away from the radial shaft conical nipple (8) and supported on a sealing element (5).
The lip seal is configured to encourage flow of saline solution along the lip seal/impeller shaft interface, while resisting blood flow along the interface.
If the centring module is placed upside down, it fulfils an additional sealing function on a secondary side by the use of an additional O-ring and a radial shaft seal ring (13).
The reinforcement (3) of the gasket (2) forms a branch (14) which extends radially inwards and to which a radial shaft conical nipple (8) arranged between the branch (14) and the rolling bodies (7) is secured.
An elastically deformable seal member (62) separates the rotor and impeller chambers, and includes an annular lip seal (66) surrounding a shaft (56) which joins the impeller and rotor.
The invention relates to a sealing ring comprising a bearing ring (1), which is connected to a lip ring (2) made of an elastomer material.
