Beschreibung
Zusammenfassung:	A pump includes a pump-head portion including a pump body and a magnet cup. The pump body defines an inlet and an outlet, and the pump body and the magnet cup together define a pump cavity. The pump includes a suction shoe situated on the pump body. The suction shoe includes an engaging portion. The pump includes a movable pumping member situated in the pump cavity and at least partially received within the suction shoe. The pump includes a permanent magnet coupled to the pumping member. The pump includes a pump-driver portion including a magnet driver located outside the magnet cup. The pump includes a pressure-absorbing member situated in the pump cavity. The pressure-absorbing member is configured to engage the engaging portion of the suction shoe such that the suction shoe is urged radially inwardly with respect to an outer edge portion of the surface of the pump body.
