Pump i.e. rotary vane pump, for conveying e.g. fluid, has housing body and/or feeding body comprising region, which is provided for contact with fluid, formed with carbon fiber reinforced silicon carbide material

摘要

The pump (10) has a pump housing body (20) comprising a feed chamber (21), and a feeding body (30) movably controlled in the feed chamber for feeding fluid (F) from an inlet (22) to an outlet (23) for the feed chamber. A region, which is provided for contact with the fluid, of the housing body and/or the feeding body is formed with a carbon fiber reinforced silicon carbide material. An outer wall region of the housing body surrounds an inner wall region of the housing body, and a carrier body (31) is rotatable around a rotation axis.
