1. The components are mounted on a steel frame structure.
2. Each controller has its own pressure measurement line.
3. The suction line should not include a strainer.
4. Check valve and throttle valve on the discharge line.
5. NFPA 20 certification does not allow negative suction for end suction and split casing pumps.
When pressure drops below the set value, jockey starts running with the signal from the pressure switch and continues running for 10minutes till the system pressure reaches the set value. If the pressure continues drop, first the main pump starts to run. If the system pressure can't supply and pressure continues drop, the standby pump starts to run.
