4 LEAKAGE TEST OF PUMP
Blank off cofferdam check pipe with a rubber gasket.
Unscrew the complete relief valve and connect a manometer to the G1/4 connection (not Framo
delivery).
Connect air/nitrogen gas supply to the snap-on coupling on the purging connection (flex. hose with
snap-on couplings is Framo delivery), and carefully increase pressure to max. 3 bar.
Stop the air/nitrogen supply and observe the pressurized volume for 15 minutes (pressure drop
indicates leakage).
Flush all parts, connections, seals etc., which have been dismantled with soapy water to be sure of
no static leakage.
Reinstall the complete relief valve and remove the rubber gasket.
