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. Mechanical, electrical, and plumbing - Wikipedia

   en.wikipedia.org/wiki/Mechanical,_electrical...

   Efficiency is optimised by changing the design of the system on both large and small scales. Heat pumps [7] and evaporative cooling [8] are efficient alternatives to traditional systems, however they may be more expensive or harder to implement. The job of an MEP engineer is to compare these requirements and choose the most suitable design for ...

5. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...

6. Volute (pump) - Wikipedia

   en.wikipedia.org/wiki/Volute_(pump)

   Pump and volute casing. A volute is a curved funnel that increases in area as it approaches the discharge port. [1] The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the ...

7. Coupling - Wikipedia

   en.wikipedia.org/wiki/Coupling

   An improvised flexible coupling made of car tyre pieces connects the drive shafts of an engine and a water pump. This one is used to cancel out misalignment and dampen vibrations. Rotating coupling. A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is ...

8. Pump as turbine - Wikipedia

   en.wikipedia.org/wiki/Pump_As_Turbine

   A pump as turbine (PAT), also known as a pump in reverse, is an unconventional type of reaction water turbine, which behaves in a similar manner to that of a Francis turbine. The function of a PAT is comparable to that of any turbine , to convert kinetic and pressure energy of the fluid into mechanical energy of the runner.
