2. Circulator pump - Wikipedia

   en.wikipedia.org/wiki/Circulator_pump

   This avoids one of the principal challenges faced by the larger, two-part pumps: maintaining a water-tight seal at the point where the pump drive shaft enters the pump body. Small- to medium-sized circulator pumps are usually supported entirely by the pipe flanges that join them to the rest of the hydronic plumbing. Large pumps are usually pad ...

3. 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.

4. Circulation evaporator - Wikipedia

   en.wikipedia.org/wiki/Circulation_evaporator

   Tubular forced circulation evaporators employs an axial circulation pump which navigates the flow of liquid in a circular motion through the system's heat exchanger in which it is superheated. Thereafter, when the liquid reaches the separator the liquid pressure decreases dramatically forcing a portion of the liquid to be rapidly boiled off.

5. Forced circulation boiler - Wikipedia

   en.wikipedia.org/wiki/Forced_circulation_boiler

   Natural circulation requires vertical piping whereas the forced circulation ensures flow in any direction. [6] The walls of the tube may be built smaller due to the greater tolerance of higher pressure losses. [6] The general forced circulation boiler has a low circulation ratio of range between three and ten.

6. Chopper pumps - Wikipedia

   en.wikipedia.org/wiki/Chopper_pumps

   A chopper pump is a centrifugal pump which is equipped with a cutting system to facilitate chopping or maceration of solids that are present in the pumped liquid. The main advantage of this type of pump is that it prevents clogging of the pump itself and of the adjacent piping, as all the solids and stringy materials are macerated by the ...

7. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
