The present invention provides a centrifugal pump for heating fluid by eddy current comprising a volute (29) and a cover (34), in which internally regarding the volute (29) there are provided: an impeller (33) positioned between two supporting annular disks (32) of magnets each comprising a plurality of permanent magnets (31); and two armatures (30) positioned at the ends of the internal assembly. In addition, the invention also provides a subsea tool for fluid heating by eddy current comprising: a centrifugal pump (1) driven by a hydraulic motor (3) by means of a shaft (11); a fluid storage tank (2) hydraulically connected to the centrifugal pump (1); at least one piloted on-off valve (4); piloted directional valves (12, 13); and a filter (7) hydraulically connected to the centrifugal pump (1).

A portable blower assembly includes a cylinder that has an exhaust port integrated into the cylinder. A handle extends around the cylinder and the handle can be gripped by a user for directing the exhaust port toward a vehicle. A blower is rotatably integrated into the cylinder to urge air outwardly through the exhaust port thereby facilitating the air to be directed onto the vehicle for drying the vehicle when the blower is turned on. A heater is integrated into the cylinder such that the heater is in thermal communication with an interior of the cylinder. The heater is positioned between the blower and the exhaust port to heat the air is blown by the blower for enhancing drying the vehicle.

An impeller pump for a dishwasher has a pump housing comprising a pump upper portion, pump lower portion and pump outer wall in which a pump chamber is arranged. It has a pump inlet into the pump housing and a pump outlet out of the pump housing and a heating device, which forms the pump outer wall, and a pump drive having a drive rotor, a drive stator having a stator winding and a bearing shaft. The bearing shaft is fixedly arranged on the pump housing and the drive rotor is fixedly connected to the drive rotor and they are rotatably arranged on the bearing shaft. The stator winding is arranged on a region of the pump lower portion which adjoins the pump chamber at the other side thereof in an outward radial direction so that between the pump chamber and stator winding only one wall of the pump lower portion extends so that the stator winding is surrounded by the pump chamber in an annular manner. It can thus be effectively cooled by water in the pump chamber.

A variable-part liquid cooling pumping unit comprising a water block unit having a water block set, flow guiding plate, and water block cover, and a pump unit having a pump housing assembly is provided. The pump housing assembly comprises an impeller cavity inlet, flow adjusting disc, impeller cavity, and impeller cavity outlet opening. Inlet and outlet ports are positioned on a same side of and plane as the pump housing assembly. More than one water block unit and pump unit are provided and interchangeable. During operation, working fluid is sucked via the inlet port through the impeller cavity inlet, pass the flow adjusting disc, into the impeller cavity, to a plurality of curved blades of a rotor assembly unit impeller. From there, the working fluid travels through the impeller cavity outlet opening, flow guiding plate, and water block set, before exiting through the flow guiding plate, and outlet port.

The disclosure provides a liquid storage device configured for storing a working liquid and including a casing and a liquid driving device. The casing includes a reservoir and an accommodation part detachably disposed on the reservoir. The reservoir has a reservoir chamber. The liquid driving device is disposed in the accommodation part and forms a liquid chamber. The liquid driving device includes an impeller located in the liquid chamber and configured to force the working liquid to flow towards the liquid chamber from the reservoir chamber.

A motor for driving a liquid end of a pump system. The motor having an inner housing having an outer surface, a mechanical actuator disposed in the inner housing, and a water jacket surrounding at least a portion of the outer surface of the inner housing to define a volume between the inner housing and the water jacket. The volume being sized to circulate water within the water jacket so as to transfer heat from the inner housing to the water.

An integrated pressurized pump shaft seal assembly for a submersible rotary fluid pump comprises an oil reservoir having a pressure equal or less than the ambient pressure external fluids surrounding the casing, the oil reservoir feeding an oil pump impeller that is mountable onto, so as to be rotated by, the rotary fluid pump shaft. The impeller is a radial hole impeller in fluid communication with an adjacent diffusion element comprising an internal diffusion bore in fluid communication with an axially vertical spiral volute diffusion chamber located between inner and outer walls of a mechanical seal housing. The centrifugal oil pump impeller pumps oil from the oil reservoir to the seal chamber through the diffusion element and the internal volute diffusion element so as to increase a pressure within the seal chamber to a positive pressure above the ambient pressure of the external fluids surrounding the pump housing.

A cover for a pump for a liquid for a household appliance, in particular for a dishwasher or a washing machine;

the cover comprising an electric heating element partially in contact with the wall, which crosses said wall, whereby said at least one electric heating element is apt to come into contact with the liquid;

the cover further comprising at least two NTC thermistors which are fixed to the outer face by a support provided with a notch;

wherein the two NTC thermistors are at a stretch of heating element separated by the wall, and are fixed to zones of the support between which said notch is provided.

An integrated pressurized pump shaft seal assembly for a submersible rotary fluid pump comprises an oil reservoir having a pressure equal to or less than the ambient pressure external fluids surrounding the casing, the oil reservoir feeding an oil pump impeller that is mountable onto, so as to be rotated by, the rotary fluid pump shaft. The oil pump impeller is in fluid communication with an internal volute diffusion element integrated into a pump component. The centrifugal oil pump impeller pumps oil from the oil reservoir to the seal chamber through the internal volute diffusion element so as to increase a pressure within the seal chamber to a positive pressure above the ambient pressure of the external fluids surrounding the pump housing.
