Centrifugal pumps are one of the most popular pumping solutions in the world due to their highly efficient and simple design, smooth flow, ease of operation and maintenance. Centrifugal pumps use one or more impellers that rotate synchronically with the pump shaft to increase the fluid’s pressure head and move it. Used in a range of industrial and marine applications, centrifugal pumps are suitable for pumping clean, low viscosity fluids such as water, fuel, oils and chemicals. This pumping solution is typically used for applications such as transferring general water supply, seawater transfer, boiler feed, water circulation and within chemical manufacturing.
High pressure centrifugal pump with horizontal structure, maximum flow 13.5 m³/ h (59.4gpm), maximum head 23m (75ft) and minimum flow 7.3 m³/ h, minimun head 20.5m (67ft). The 3-phase centrifugal water pump has advantages of stable operation, low noise, low failure rate, convenient maintenance, and less land occupation.
The efficiency is lowered and the power consumption is increased. The centrifugal pump is generally designed to have an efficiency point near the rated condition point. When the centrifugal pump is operated at a low flow operating point, its operating efficiency will drop rapidly. Under normal circumstances, the smaller the flow rate leads to a lower efficiency, so it is very uneconomical to operate in low-flow conditions. In normal conditions, it is necessary to refit the appropriate high-efficiency small pump at this time.
Pump is a very important auxiliary equipment for a power plant. It has a wide application in all parts of the power plant. Feed pump, circulating water pump, condensate pump, ash pump, oil pump, etc., these auxiliary engine running state not only affects the safety of power plant, but also plays an important role in the economy of power plants and energy conservation!
According to their function, the power plant is divided into two major systems: the pump turbine unit auxiliary pump, boiler feed water pump, booster pump, condensate pump) desulfurization circulating pump (the main loop desulphurization pump, FGD peripheral pump, the absorber system)
This pump has only one impeller and the highest increase in pressure head is 125 meters. The simple structure, stable operation, high speed, lightweight, small volume, high efficiency, large flow capacity, and easy maintenance are essential advantages of single-stage pumps. Single-stage centrifugal pumps can be classified into horizontal pumps, vertical pumps, single-suction pumps, and double-suction pumps.
In an axial flow pump, the fluid moves parallel to the shaft. This procedure resembles the working of a propellant. The most significant application of this pump is when there is a large flow rate and very little pressure head. For example, they are common in dewatering pumps and water circulation pumps.
The fluid pressure at the outlet of the pump can be very large. Therefore, if a very high head at discharge is needed, the multistage pump is used. In this design, impellers are connected in series to increase the fluid pressure at each stage.
As the name implies, in a mixed flow pump, the fluid flows mixing both radial and axial properties. So, that is a tradeoff between axial and radial pumps. Mixed pumps operate at high flow rates with a decent increase in the head.
Single-suction will not suffice when the flow rate is too high. In this case, double suction centrifugal pumps are used. The impeller of this pump is engineered so that fluid enters from both sides in comparison with the single side in a normal case.
In a single-suction centrifugal pump, the fluid flows into the inlet, and the entire liquid immediately flows into the impeller eye (the inlet of the impeller). The centrifugal force then produces pressure as the water leaves the impeller.
Horizontal pumps are more commonly used because they are easy to maintain. In this type, the shaft is positioned horizontally.
In a vertical pump, the shaft is in a vertical orientation, and the pump is usually placed in the sump. These pumps are used in limited spaces. For example, pump in borewell and sump collection are of this type.
The BOB is a horizontal centrifugal pump that has a robust bearings bracket making it ideally designed for large volumes of water. Available in different executions, the BOB can be outfitted with self-priming options that include vacuum and electric. The BOB model includes case wearing rings to prolong the life span of the impeller and casing.
