All measurements and calculations should be done for clean water at 20°C.

- For the state where the flow rate reaches 150% of the working point, the required power of the engine must be determined and, if requested by the employer, the rated driving power must be selected based on this state.

- To ensure the performance of the pumps in the required conditions, the manufacturer must test each pump separately with water and provide test certificates. In the test certificate, the performance curve, engine absorption power and efficiency curve should be shown.

- Centrifugal pumps should not be used when the pump has to perform negative suction.

Each pump must have a separate plate. The working pressure, working point flow rate, rotation speed and engine performance factors should be mentioned on the pump nameplate.

- Each pump must have a pressure gauge on the thrust and suction sides.

- The shell of each pump must have a pressure relief valve.

- The coupling of the pump motor and other rotating parts of the pump must be equipped with a guard.
