  2. Centrifugal pump - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump

    Magnetically coupled pumps, or magnetic drive pumps, vary from the traditional pumping style, as the motor is coupled to the pump by magnetic means rather than by a direct mechanical shaft. The pump works via a drive magnet, 'driving' the pump rotor, which is magnetically coupled to the primary shaft driven by the motor. [8]

  3. Submersible pump - Wikipedia

    en.wikipedia.org/wiki/Submersible_pump

    A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...

  4. Return connecting rod engine - Wikipedia

    en.wikipedia.org/wiki/Return_connecting_rod_engine

    Vertical blowing engine. A blowing engine is a large stationary steam engine directly coupled to air pumping cylinders. They are used to provide the air blast for blast furnaces and other forms of smelter. As the working cylinder and the driven load are both reciprocating pistons, they may be directly coupled by their piston rod.

  5. Pumping station - Wikipedia

    en.wikipedia.org/wiki/Pumping_station

    In this configuration, submersible sewage pumps with closely coupled electric motor are mounted within the wet well itself, submerged within the sewage. Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe.

  6. Axial-flow pump - Wikipedia

    en.wikipedia.org/wiki/Axial-flow_pump

    An axial-flow pump for industrial use. An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe.The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.

  7. Centrifugal pump selection and characteristics - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump_selection...

    Pump curves are quite useful in the pump selection, testing, operation and maintenance. Pump performance curve is a graph of differential head against the operating flow rate. They specify performance and efficiency characteristics. Performance tests are done on the pumps to verify the claims made by the pump maker.
