A submersible pump assembly that is capable of transporting water from a body of water, and methods of use thereof, are herein disclosed. The pump assembly includes a submersible pump, a power source for the pump, and a hose that pumps water from the body of water to a location on land. In certain embodiments, one or more filters may be used to remove particulates from the water prior to entering the submersible pump. Further, an anchor and warning pole may be incorporated to prevent the submersible pump from being displaced, and to provide notification to others in the water of the presence of the submersible pump and anchor.

An electric oil pump with an one-way valve is provided, which includes a control box. The control box is provided with a communication pipe and a control board, one end of the communication pipe is connected with an oil-extracting pipe, the other end is connected with an oil outlet pipe, a pump body is arranged in the oil outlet pipe, and a bottom of the control box is rotatably installed with a threaded cap. When the oil pump is, working, the gasoline is blocked by the one-way valve and transported to the oil outlet pipe via the oil-extracting pipe during the oil delivery process, and the negative pressure in the oil drum makes the outside air enter into the oil drum through the one-way valve when the oil pumping is completed, so as to maintain the pressure balance between the inside and outside of the oil drum.

The invention disclosed is a sump basin protective sleeve that replaces the use of common gravel as a filtering medium around sump pump basins. Disclosed is a protective sleeve having an inner layer and outer layer made of filtering microfiber whereby the inner layer and the outer layer are joined to each other whereby a geosynthetic aggregate is installed in between the inner layer and outer layer and cell pockets formed to evenly disperse the aggregate and also to provide a plurality of drain line entrances by cutting into a desired cell pocket to install a drain line without disturbing the aggregate contained in the remaining cell pockets.

A solar powered sediment capture system is disclosed for collecting sediment at environment sites such as lakes and rivers. A mechanical pump directs water from a containment basin to an upper tank and an antistatic pressure tank, both which are elevated. Gravity flow from the upper tank generates vacuum to establish a syphon for drawing a flowable sediment slurry from an environmental borrow site to a filter. Effluent from the filter passes down to the containment basin, which has water level at a lower elevation than that of the borrow site. Anti-static and driller conduits permit gravity flow from the anti-static tank to suspend the sediment and to maintain the slurry at the syphon inlet in a flowable state.

The invention relates to a method for monitoring and controlling the operation of a pump station (1) comprising a tank (8) for storage of a liquid and at least one pump (2), the pump station (1) further comprises an outlet conduit (5) connected to the pump (2), the method comprising the steps of: determining the Geodetic head (Hgeo) of the pump station (1), determining the pumped

Flow (Q) for a given pump operation duty point, determining the consumed Power (P) for the given pump operation duty point, and determining a Normalized Specific Energy (nSE) of the pump station (1) based on the determined values of Geodetic head (Hgeo), pumped Flow (Q) and consumed Power (P), by means of the formula (nSE)=(P/Q)/Hgeo.

The invention relates to a method for determining a pumped flow (Q) from a pump by a flowmeter that comprises an internal pressure sensor configured to measure the static liquid pressure (H-in) at the inner surface of the flowmeter, and an external pressure sensor configured to measure the static liquid pressure (H-out) at the outer surface of the flowmeter. The method comprises measuring the static liquid pressure (H-in) at the inner surface, measuring the static liquid pressure (H-out) at the outer surface, determining the Static head (H-stat) of the pump based on the measured static liquid pressure (H-in), the measured static liquid pressure (H-out) and a pressure difference (H-diff) corresponding to the difference in height position between the internal pressure sensor and the external pressure sensor, and determining the pumped Flow (Q) by using the determined Static head (H-stat) of the pump from a predetermined pump specific Q-(H-stat)-relationship.

A pump includes a reservoir configured to receive a fluid pressurized by a boost pump. The pump also includes at least one pumping mechanism configured to receive a first flow of fluid from the reservoir and direct the first flow of fluid into a discharge passage of the pump without pumping the first flow of fluid when priming the pump. The at least one pumping mechanism is disposed in the reservoir such that the fluid in the reservoir surrounds at least a portion of the at least one pumping mechanism. The discharge passage is configured to output the first flow of fluid from the pump. The pump further includes a bypass passage configured to communicate a second flow of fluid from the reservoir to the storage tank.

An electrical submersible pump (ESP) isolates its motor lubricant from pumped product without requiring a bellows, diaphragm, bladder, or external lubricant pressurizing system. A pair of nested isolation chambers below the motor housing are filled with a barrier fluid that is non-reactive, non-miscible, and higher in density than the pumped product and the motor lubricant. As the motor lubricant expands and contracts after pump start-up and shut-down, motor lubricant and barrier fluid are exchanged between the motor housing and the isolation chambers via three interconnections, while pumped product is exchanged with the inner barrier chamber, while being isolated from the motor housing. The interconnections extend between the bottom of the motor housing and the bottom of the outer barrier chamber, between the top of the outer barrier chamber and the bottom of the inner barrier chamber, and between the top of the inner barrier chamber and the pumped product.

A thermoelectric pumping apparatus for use with a heating device includes a water receptacle. A thermoelectric device includes a “cool” side coupled to the receptacle and an opposed “hot” side, the thermoelectric device generating current upon a temperature differential between the cool and hot sides. A conduction member is proximate the hot side and in selective communication with the heating device. A spring is positioned between a top side of the conduction member and receptacle, the spring being movable between a compressed configuration at which the conduction member is in thermal communication with the hot side of the thermoelectric device and an extended configuration at which the top side of the conduction member is not in thermal communication with the hot side of the thermoelectric device. A water pump is in fluid communication with the water in the receptacle and selectively energized by the thermoelectric device to output the water.
