A method of making a pump (10) including a polymeric pump housing (12) and a drive shaft (14) mounted for rotation in a bearing (16), the bearing (16) having on an exterior surface at least one engagement formation (44),—the method including the step of molding the pump housing (12) around the bearing (16) such that the housing (12) co-operates with the engagement formation (44) to restrict movement of the bearing (16) with respect to the housing (12). |
