This relates to apparatus that can form dilute aqueous firefighting compositions from an aqueous concentrate.

Described is a wear part for minerals processing equipment. The wear part comprises an inner surface for contact with slurry when the minerals processing equipment is in use and an outer surface of the wear part. The wear part further comprises at least one sacrificial wear sensor located at a predetermined distance between the inner surface and the outer surface, the at least one sacrificial wear sensor being arranged to wirelessly communicate with a remote wear monitoring unit.

A system includes an electric submersible pump (ESP) configured for pumping fluid through a flow path. An autonomous inflow control device (AICD) is included in fluid communication with the flow path to separate one of gas or liquid out of the flow path. A method includes producing liquid from a wellbore using an electric submersible pump (ESP) in the wellbore. The method includes bypassing gas from a headspace the wellbore using an autonomous inflow control device (AICD) to prevent gas locking the ESP.

A device for protection of wastewater pumps for wet accumulation chambers has a separation chamber provided with a discharge pipe for discharging wastewater into a sewerage network. A supply pipe connected to the separation chamber supplies solid particles containing wastewater into the separation chamber. A reversing valve arranged between the supply pipe and the separation chamber prevents reverse flow of wastewater into the supply pipe. A bidirectional pipe connected to the separation chamber connects the separation chamber with a pump, where the bidirectional pipe serves to supply wastewater from the separation chamber into the pump positioned in the wet accumulation chamber and for reverse flow of wastewater from the pump into the separation chamber to a discharge pipe. A solid particles separator arranged between the separation chamber and the bidirectional pipe separates solid particles contained in wastewater in the separation chamber.

An inducer and a submersible pump for pumping a slurry comprising solids and viscous fluids, the inducer mountable to the pump's drive shaft adjacent to and immediately upstream of an impeller mounted on said shaft. The inducer comprises a hub, two to four inducer blades extending outwardly from and wrapping helically around the hub, the hub and the inducer blades defining a plurality of channels A trailing edge of each inducer blade is positioned snugly adjacent to and in fluidical alignment with a leading edge of a corresponding impeller blade when the inducer is mounted on the drive shaft of the pump, such that a velocity curve of the slurry is smooth as the slurry travels from a leading edge of the inducer blades to the leading edge of the impeller blades.

The pump according to the present disclosure includes: a housing having a suction chamber and a discharge chamber formed therein; a suction part extending outwardly from a circumferential surface of the housing, and having a suction passage formed therein through which a fluid is introduced into the suction chamber; a discharge part disposed under the suction part, extending from the circumferential surface of the housing in a direction opposite to the suction part, and having a discharge passage formed therein through which the fluid is discharged from the discharge chamber; a partition wall dividing the suction chamber and the discharge chamber, and having a communication hole formed at a center thereof for allowing the suction chamber to communicate with the discharge chamber; an impact body disposed toward the suction part so as to come into contact with the fluid introduced into the suction chamber through the suction passage; and a gas discharge part disposed at an upper portion of the circumferential surface of the housing and communicating with an outside so that gas, separated from the fluid in contact with the impact body, is discharged, wherein the suction part extends in one direction perpendicular to a virtual center line passing through the housing, and the impact body is disposed in a direction opposite to an extending direction of the suction part with respect to the virtual center line.

A centrifugal pump (1) including: a pump housing (3) enclosing a pump chamber (13), the pump chamber (13) including a suction inlet (15) and a pressure outlet (17); an impeller (19) rotatably arranged within the pump chamber (13) for being driven to rotate about a rotor axis (R), the suction inlet (15) being located coaxial with the rotor axis (R); and at least one stationary scraper (39). The impeller (19) includes an impeller base (31) and at least one or more impeller vanes (33) extending from the impeller base (31) towards the suction inlet (15). Each of the impeller vanes (33) includes a radially innermost vane path (45) describing during impeller rotation a central volume (41) that is wider towards the suction inlet (15) than towards the impeller base (31) and configured to receive the at least one scraper (39) projecting from the suction inlet (15) into the central volume (41).

Water Reservoirs and wetlands are a major source of methane emissions contributing to greenhouse gases. The annual flood seasons contribute to movement and accumulation of sediments behind irrigation and hydropower dams. These sediments accumulate year after year, lead to loss of water storage capacity and ability to produce hydro-electricity. The invention being proposed to dredge deep sediments from reservoirs operates on the principle of using gaseous fuel from an external pipeline or collected methane emissions as fuel for a submersible internal combustion slurry system. The invention combines the features of an internal combustion liquid piston engine with a slurry turbine driving a dredging cutter. Slurry entering into the system forms a column that is set in oscillation through the explosion of air and fuel and is then pumped to shore.

The invention, comprises a pumping apparatus, system and method for increasing the flow of the in a first direction to boost liquid flow and in a reverse second direction to remove blockages and/or self-clearing, with operation having an rotor/impeller that can use a shredder and/or shearing action utilizing blades for processing to pass solids, debris and other things to prevent clogging and/or self-cleaning of the unit.
