7.1 Operation
¾ It is recommended to open the bypass valve during start-up. The bypass valve that connects the suction and discharge of the
pump will make the filling procedure easier. When the operation is stable, the bypass valve can be closed.
¾ If the pumped liquid contains air or the operating pressure is lower than 6 kg/cm², it is advisable to leave the bypass valve
open. If the operating pressure constantly exceeds 6 kg/cm², the bypass valve must be closed. Otherwise, the material at the
opening will be worn out because of the high liquid velocity.
