摘要： A water system for a hydraulic frac station. The water system includes a water source, a water retention pit, a pump, a riser station, and a water recycling system. The pump is configured to channel water from the retention pit to the riser station and to the hydraulic frac station. The water from the retention pit is channeled to the hydraulic frac station, which in turn is channeled to the recycling system via the riser station.

摘要： A rotary blood pump includes a casing defining a pumping chamber. The pumping chamber has a blood inlet and a tangential blood outlet. One or more motor stators are provided outside of the pumping chamber. A rotatable impeller is within the pumping chamber and is adapted to cause blood entering the pumping chamber to move to the blood outlet. The impeller has one or more magnetic regions. The impeller is radially constrained in rotation by magnetic coupling to one or more motor stators and is axially constrained in rotation by one or more hydrodynamic thrust bearing surfaces on the impeller.

摘要： An inlet sieve for a self-priming floating pump features a bottom wall that is carried in a position that underlies the inlet of the self-priming floating pump at a distance therebelow with the inlet of the pump aligned with an axis that passes through the bottom wall of the sieve. A perforated outer wall of the sieve stands upward from a top side of the bottom wall and extends about the axis. The bottom wall features an outer area that spans inwardly from the perforated outer wall toward the axis, and a protuberance that bulges upwardly from the outer area to an apex of the protuberance that is situated at the axis. Water flowing inwardly toward the protuberance from different radial directions is directed smoothly upward into the inlet of the pump with minimal turbulence in order to optimize the performance of the pump.

摘要： A self-cleaning screen for shallow water pumping includes a rotatable drum made of mesh material for removing debris from water passing into the drum, and a suction chamber within the drum for feeding water to a suction pipe connected to a centrifugal pump. Inlet openings are arranged across a bottom side of the suction chamber. A check valve assembly is provided to prevent water from back flowing through the inlet openings, to thereby maintain a prime in the suction pipe when the pump is off. The check valve assembly includes valve members that are slidably mounted above the inlet openings for movement between closed and open positions. The valve members move upwardly from their closed positions to their open positions upon movement of water through the inlet openings into the suction chamber, and return to their closed positions by force of gravity when water stops flowing into the suction chamber.

摘要： A buoyant water pump system for reducing the difficulty involved in removing the pump from a well. The buoyant water pump system includes a conduit having a lumen and a lower end for inserting into the well. A pump assembly for pumping water from the well is mounted on the lower end of the conduit. The pump assembly includes a pump mounted on the conduit adjacent to the lower end thereof, and having an outlet that is fluidly coupled to the lumen of the conduit. A buoyant member is mounted on the conduit adjacent to the pump assembly to keep the pump assembly afloat.
