Charging Instructions for Pulsation Dampeners

CHARGE TO 80%- 90% OF SUCTION PRESSURE OR THE MAXIMUM CHARGE PRESSURE OF THE CARTRIDGE, WHICHEVER IS LESS. THIS IS ONLY AN APPROXIMATION.

(YOU MAY FIND IT NECESSARY TO DECREASE THE PRESSURE IN THE SUCTION CARTRIDGE TO ACHIEVE OPTIMUM PUMP PERFORMANCE.)

Shut down pump and relieve line pressure from discharge side before closing suction valve. After discharge line is relieved of pressure, close suction line valve and drain suction line.
Open bleeder valve ’A’.
Remove loading valve protector cap ’B’.
Remove cap from loading valve ’C’.
Loosen safety nut ’D’ three full turns.
Using NITROGEN ONLY, charge the cartridge through loading valve ’C’ to the recommended operating pressure (90% of suction pressure). (DO NOT EXCEED MAXIMUM CARTRIDGE CHARGE PRESSURE).
Tighten safety nut ’D’ on loading valve ’C’.
Replace loading valve protector cap ’B’
Open suction valve. When air from bleeder valve ’A’ is evacuated, close bleeder valve ’A’.

Shut down pump and relieve line pressure.
Open bleeder valve ’A’.
Remove loading valve protector cap ’B’.
Remove cap from loading valve ’C’.
Loosen safety nut ’D’ three full turns.
Using NITROGEN ONLY charge the cartridge through loading valve ’C’ to correct charge pressure (Click here for chart).
NOTE: DO NOT EXCEED MAXIMUM CARTRIDGE CHARGE PRESSURE (ON CASE LABEL).
Tighten safety nut ’D’ on loading valve ’C’ and replace cap.
Replace loading valve protector cap ’B’.
Open suction valve. When air from bleeder valve ’A’ is evacuated, close bleeder valve ’A’.
