摘要： The present invention relates to a volute pump for delivering a liquid containing fibrous substances. The volute pump includes an impeller (1) having a vane (2), and an impeller casing (5) which houses the impeller (1) therein. The impeller casing (5) includes a volute chamber (7), a suction port (3) and a discharge port (4) which communicate with the volute chamber (7), and a tongue portion (10) which forms a starting portion of the volute chamber (7). A groove (18), extending from the suction port (3) to the volute chamber (7), is formed in an inner surface of the impeller casing (5). An intersection point (B), where a terminal end of the vane (2) passes across the groove (18) as viewed from an axial direction of the impeller (1), is located at an opposite side from the tongue portion (10) with respect to a central point of the impeller (1).

摘要： A pump housing has a spiral housing and includes a suction channel (14) which runs out in a space (15). The space (15) is for arranging an impeller (6), rotatable about a rotation axis (5), and includes a spirally peripheral channel (16) open to the space (15) and running out into a pressure channel. A receiver (20) for a differential pressure sensor is provided within the pump housing. A first sensor channel (22) is provided, which connects the receiver (20) to a pressure-side interior of the pump housing. A second sensor channel (23) connects the receiver (20) to the pressure-side interior of the pump housing. The receiver (20) for the differential pressure sensor is arranged between the spirally peripheral channel (16) and the suction channel (14), so that the channels can be formed by way of simple bores.

摘要： A pump casing for a centrifugal pump, which comprises an inlet opening, a discharge outlet, and a transition surface extending between an inner peripheral surface of the main pumping chamber and an inner peripheral surface of the discharge outlet, the transition surface arranged for separating an in use exit flow of material in the discharge outlet from an in use recircula tion flow of material in the main pumping chamber. The transition surface has a cutwater having a profiled section which comprises a protrusion which extends irregularly from an otherwise generally rounded arched or U-shaped transition surface and is configured such that, in use, the velocity and/or turbulence resulting from the in use flow of the material being pumped in the main pumping chamber is reduced.

摘要： A biological fluid transport device comprises a cutwater at the junction of at least two blood flow paths. The cutwater is substantially straight, substantially vertical, or both. At least one of the fluid paths may be tubular, and in some embodiments all of the fluid paths are tubular. The shear sensitive fluid may be, without limitation, blood, blood-based combinations, cell culture media, cell suspensions, proteins, and microcapsule suspensions. The device may be part of an extracorporeal circuit (e.g., blood during heart-lung bypass procedures or blood processing), but it need not be. Preferred embodiments of the device include, without limitation, kinetic pumps, mass transfer devices, filters, reservoirs, and heat exchangers.

摘要： The invention concerns a device for pump housings for centrifugal pumps for pumping of polluted liquids. In order to decrease the influence of radial force acting upon the impeller during operation, a partition wall (5) is arranged along a part of the turn in that part of the spiral formed pump housing that has the biggest diameter. In order to decrease the risk that pollutions will stick to the wall (5), it is split up into two parts (6) and (7) with an intermediate, longitudinal slot (10). The leading edges of said parts (6) and (7) are swept backwards into the slot (10).
