End Suction Centrifugal
Generally, an incorrect cement base is the cause of premature failure and this invalidates the warranty
period.

PIPES
The installation must be done according to the arrangement shown in the Figure:
1. Make sure that the suction and delivery ducts do not transmit any stresses to the pump, by installing
sufficiently strong supports. If this is not done, the pump could become misaligned and even break.
2. Fit any check valves (between the pump and the delivery valve) in the following cases:
- In very long pipes.
- If the head is high.
- If the operation is automatic.
- When you fill a tank under pressure.
- When the operation is in parallel.
3. Mount air relief valves, if required, in those parts of the installation where it is impossible to avoid the
formation of air bubbles. However, they must not be fitted at points where the pressure is less than
atmospheric pressure since the valve would suck in air rather than expel it.
4. To reduce the effect of a water hammer, mount a check valve with spring.
