Vacuum breaker- How to check
Vacuum breaker- How to check
(OP)
Our tanks wee protected by PSVs. The set pressures are +0.065mBar for the pressure and -0.004 mbar. What we have is only a hand pump. Is it possible to check it with our hand pump?





RE: Vacuum breaker- How to check
The hand pump might give you 6.5 kPa air pressure, but no vacuum, provided you have an accurate gauge for measuring that pressure. Most impostant, if your tank is rather large in size, it will take you weeks to generate the 6.5 kPa with a hand pump, for testing the relief valve. Also, you might wish to review the testing method of the relief valve installed on the top of the tank.
Best of luck,
