专利汇可以提供Pump apparatus专利检索，专利查询，专利分析的服务。并且Pump apparatus embodying a flexible conduit which is collapsed to effect a pumping action. In one embodiment the flexible pumping conduit forms a priming mechanism for a centrifugal pump and the actuating member for collapsing the conduit is connected to the pump shaft by a drive coupling which prevents operation of the mechanism when the pump is primed. In another embodiment the actuating member is connected to a shaft by a spiral spring which permits the member to shift radially with respect to the shaft.，下面是Pump apparatus专利的具体信息内容。
