6.3.5. VENT
Fix a 1/4” valve for air vent beyond the discharging pipe and prior to any other component. In presence of dangerous
fluids, the air vent must be directed toward a safe area. The air vent is very important and it’s essential during the start-up
/ removal to allow the proper pump’s fill up/emptying.
6.3.6. DRAIN
Vertical pumps do not require any drainage valve, because they spontaneously drain when they are lifted from the tank.
Any remaining liquid in the flushing pipes or in the column are removed through a specific wash and drained through drain
holes on the pump.

6.3.7. CONTROL INSTRUMENTS
Install a pressure gauge on the discharge pipe and minimum/maximum level sensors in the tank. This equipment is
necessary for the proper pump’s adjustment and running, also for faults detection or any plant failure. In case of any
complaint concerning pump performances, it’s necessary to measure the discharge pressure values stated close to the
pump and levels of medium in the tank. Pressure gauge connections must be placed in a position as not to disturb
measurement of valves, filters or other elements causing any pressure drops.
