Calculation of minimum Inlet Pressure

If the pressure in the pump is lower than the vapor pressure of the medium, cavitation will occur, which will affect the performance of the pump. To avoid the cavitation and ensure the pump inlet has a minimum pressure, the maximum suction head should be calculated as below:


Pb: Atmospheric pressure, bar (In close pipeline system, it can be considered as the system pressure);
NPSH: Net positive suction head, m (Value at a maximum flow of Q-NPSH curve);
Hf: Suction pipeline loss (Value at a maximum flow of the corresponding pipeline);
Hv: Medium vapor pressure, m (Medium vapor pressure at corresponding temperature, the default medium is water, as shown in figure4 on the right);
Hs: Safety margin, m, general value is 0.5.
Calculation result: if H is positive, the pump is installed in a suction way, otherwise, it is installed in the downdraft way.

Note: It is not necessary to do the above calculation under general conditions. Only when we use the pump in the following situations do we need to calculate the H:
1. Medium temperature is high;
2. The velocity of flow is larger than the rated value;
3. Suction head is big or the inlet pipeline is long;
4. System pressure is small;
5. Inlet condition is bad.

Calculation of minimum Inlet Pressure

Selection of Pumps

Selection of pumps should be based on:

  1. Duty point of the pump
  2. Dimensional data such as pressure loss as a result of height differences, friction loss in the pipework
  3. Pump efficiency
  4. Pump materials
  5. Pump connections
  6. Commonly used mechanical seal configuration tables

1. Duty point of the Pump
From a duty point, it is possible to select a pump on the basis of the curve charts shown in “performance curves/technical” data.

2. Dimensional Data
When sizing a pump the following must be taken into account:

  • Required flow and pressure at the draw-off point.
  • Pressure loss as a result of height differences.
  • Friction loss in the pipework (Hf) (Refer to Fig.1) it may.
  • Highest efficiency at the estimated duty point.
  • NPSH value.
  • For calculation of the NPSH value, see the corresponding curves chart.

3. Pump Efficiency
Before determining the best efficiency point, the operation pattern of the pump needs to be identified. If the pump expected to operate as the same duty point, then select a BL pump which is operating at a duty point corresponding with the best efficiency of the pump.
As the pump is sized on the basis of the highest possible flow, it is important always to have the duty point to the right on the efficiency curve (eta) in order to keep efficiency high when the flow drops.

Selection of Pumps

4. Pump Material
The material variant should be selected based on the liquid to be pumped. BL wetted parts are made of AISI304. BLT pump body is made of cast-iron.

5. Pump Connections

The selection of pump connection depends on the rated pressure and pipework. The vertical centrifugal pump offers a wide range of flexible connections such as:

  • Pipe thread
  • Oval flange
  • DIN flange
  • Other connections on request
  • Commonly used mechanical seal configuration tables

Maximum Work Pressure

The limits of pressure and temperature are shown in the following fig. 4, the pressure and temperature are shown in the fig. 4.

Maximum Ambient Temperature

When the pump is operating in the place where the ambient temperature is higher than 40℃ or altitude is higher than 1000m, the output power of motor P2 will decrease because of poor cooling caused by low air density. Therefore, in that case, the vertical pump should be equipped with a high-power motor.
