Centrifugal Pumps Characteristics | Marine Notes

Centrifugal pump therefore is not a self-priming pump. In such case, where normally at the start of the pump the level of the liquid is below the eye of the pump, a self priming unit is normally attached to the pump which helps to create vacuum at the eye of the impeller hence priming the pump.

steam boiler feed pumps & high pressure boiler feed water pumps
Steam Boiler Feed Pumps & High Pressure Boiler Feed Water Pumps

As taking suction from a condensate system is a high pressure application, steam boiler feed pumps are generally high head, low flow pumps, making multistage pumps a common choice. Side channel pumps are also a popular solution for high pressure boiler feed water pumps thanks to their ability to pump liquids with gas content.

A common application of the multistage centrifugal pump is the boiler feedwater pump. For example, a 350 MW unit would require two feedpumps in parallel. Each feedpump is a multistage centrifugal pump producing 150 l/s at 21 MPa. All energy transferred to the fluid is derived from the mechanical energy driving the impeller.

The pump displacement is hydraulically controlled via the pressure regulator on each pump and by this system, the oil delivery from the hydraulic pumps will always be the same as the oil consumption for the hydraulic motors. To control and limit the speed of the motor, a control valve is fitted for each motor.

centrifugal pump drives for boiler feed service
Centrifugal Pump Drives for Boiler Feed Service

centrifugal pumps for boiler feed service. Pumps used are either multi-stage or high speed units driven by electric motors or steam turbines. In the past, due to the low cost of energy, the majority of the small and medium size steam plants have practi­ cally eliminated steam turbine driven boiler feed pumps from the service.

Different Types of Pumps - Centrifugal Pumps - Process Industry

To ensure that a centrifugal pump remains primed and does not become gas-bound, most centrifugal pumps are located below the level of the source from which the pump is to take its suction. The same effect can be gained by supplying liquid to the pump suction under pressure supplied by another pump placed in the suction line.

Centrifugal pumps are often operated over a wide range of conditions. For example, many cooling systems experience variable loads caused by changes in ambient conditions, occupancy, and production demands. Boiler feed pumps have to adapt water flow to the changing demand of steam for power generation.
