Sizing Pulsation Dampeners Is Critical to Effectiveness Pressure variation is an important consideration when determining the appropriate size pulsation dampener needed for an application. By David McComb, Blacoh Fluid Control Pumps & Systems, April 2014 Positive displacement pumps effectively pump fluid at a constant average flow rate.

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 (use chart below).
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’.
WARNING
THE USE OF ANY GAS OTHER THAN NITROGEN IS EXTREMELY DANGEROUS.
