Methods, systems, and computer-readable medium to perform operations including: determining, based on at least one dimension of an annulus of a wellbore, a respective downhole position at which to position at least one of an upper sensor and a lower sensor of a downhole pumping tool that includes a pump; positioning the downhole pumping tool in the wellbore such that at least one of the upper sensor and the lower sensor are positioned at the respective downhole position; in response to the upper sensor detecting a first fluid level in the annulus, activating the pump so that the pump pumps fluid from the annulus into a tubing of the wellbore, where the tubing carries the fluid to the surface; and in response to the lower sensor detecting a second fluid level in the annulus, deactivating the pump, where the second fluid level is below the first fluid level.

Owners of sump pumps often have no way of identifying a sump pump is failing unless they are home to witness a failing sump pump in real-time. Current solutions to this issue rely on the use of expensive electronics to help alert the owner of a failing sump pump. The present disclosure offers an inexpensive solution to extend a time in which an owner can confirm the sump pump has failed or is about to fail. Namely, the present disclosure features a level indicator which retains some water in the event the water rises above a predetermined level.

The present application generally relates a system for duplex control of redundant passively-actuated electronic devices. In one embodiment, the system comprises a housing, a controller mounted inside the housing, an input/output (I/O) interface integrated with the housing that includes a first port configured to electrically couple a power input to the controller, a second port configured to electrically couple a first pump to the controller, and a third port configured to electrically couple a second pump to the controller, and a set of relays connected to the second port and the third port. In response to a current sensing circuit sensing that a first current indicates that the-first pump has shut off, the controller may activate the second pump and deactivate the first pump by controlling the set of relays to disconnect the power source from the first pump and to connect the second pump to the power source.

A sediment capture syphon apparatus for capturing sediment from a borrow site is disclosed. The apparatus comprises a containment basin having a containment basin pump valve and a vacuum tank vacuum valve configured to pump water to a vacuum tank. The vacuum tank is connected to an anti-static pressure tank and a backwash tank via one or more valves and conduits. The containment basin is further connected to a separator tank configured to pull the sediment deposits from a submerged filter. A filter assembly is configured to deposit the sediment in the deposited location. The apparatus further includes a buoyancy lift configured to exert a buoyancy lift float mechanism to float deposit and a waterfall tank to receive water flow from the filter assembly by creating pressure. The apparatus is further connected to an electrical power source to power a battery comprising one or more switches via a wire.

The present invention provides a sump pump system, including a sump pump monitor and application. The sump pump system includes a sump pump. Components of the sump pump system are installed in and/or near a sump. The sump collects liquid, such as water, from an inlet pipe. The sump pump is operable to remove water from the sump. The sump pump is fluidly connected to a discharge pipe. The discharge pipe is operable to carry water from the sump pump to a storm sewer or other discharge point.

A hydraulic pump system includes a housing defining a tank for containing hydraulic fluid in use; one or more pump modules each comprising a hydraulic pump for supplying hydraulic fluid from the tank to a hydraulic system; and a mounting arrangement; wherein the or each pump module is mounted to the housing by the mounting arrangement.

A heat insulating vessel for a low temperature liquefied gas pump, which includes an inner tank configured to accommodate low temperature liquefied gas, an outer tank provided externally around the inner tank, and a low temperature liquefied gas pump disposed inside the inner tank. The outer tank has an outer tank upper part that is an upper end portion thereof, and an outer tank body other than the outer tank upper part. A lid structure having a heat-insulated structure detachably fitted into an upper part of the inner tank. The pump is fixed to the lid structure, and a suction pipe and a discharge pipe are insertedly fixed to the lid structure. A vacuum insulating layer is provided between the inner tank and the outer tank. With this heat insulating vessel for the low temperature liquefied gas pump, adiabaticity of the lid structure and maintainability of the pump are increased.

A vortex fountain or waterer that incorporates measures to induce swirl in liquid moving toward a drain opening of the fountain to inhibit the accumulation of debris is provided. The fountain may have a bowl including a base surface having a slope that is configured to create a vortex in the liquid flowing toward the drain opening to induce movement of a quantity of water, where the bowl is located above a basin configured to hold the liquid. The fountain may also include a pump outlet jet that can be positioned about the bowl to induce swirl about the bowl. The fountain may also include a drain tube located beneath the drain opening, and an extended guide tube extending downwardly towards the bottom of the basin. When the liquid passes through the drain, drain tube, and guide tube, oxygen is incorporated into the liquid as the liquid reaches the basin.

A pump cartridge comprising an external housing including a lateral wall, a first fin extending from a first side of the lateral wall, and a second fin extending from a second side of the lateral wall. The second side of the lateral wall may be opposite the first side of the lateral wall, such that the fins are on opposite sides of the lateral wall. The pump cartridge may be part of a pumping system further comprised of a chassis comprising a pump basin including an interior side wall, a first tab extending inwardly from the interior side wall, and a second tab extending inwardly from the interior side wall and opposed to the first tab. The first fin of the cartridge is reversibly engageable with the first tab of the chassis and the second fin of the cartridge is reversibly engageable with the second tab of the chassis.

Disclosed are methods, systems, and computer-readable medium to perform operations including: determining, based on at least one dimension of an annulus of a wellbore, a respective downhole position at which to position at least one of an upper sensor and a lower sensor of a downhole pumping tool that includes a pump; positioning the downhole pumping tool in the wellbore such that at least one of the upper sensor and the lower sensor are positioned at the respective downhole position; in response to the upper sensor detecting a first fluid level in the annulus, activating the pump so that the pump pumps fluid from the annulus into a tubing of the wellbore, where the tubing carries the fluid to the surface; and in response to the lower sensor detecting a second fluid level in the annulus, deactivating the pump, where the second fluid level is below the first fluid level.
