Inddition to the ZM pulsation dampener Coorstek offers:. Inline gas-charged pulsation stabilizers. Appendage-type stabilizers. FlowGuard® pulsation dampers. Replacement bladders and repair kits:. Continental Emsco® PD-45, PD-50. Hydril® K-Series, IP-Series ZM-SERIES PULSATION DAMPENER VOLUME ZM-12. 3.9 gallons (14.7 liter). Flowguard USA is your online source for information regarding Flowguard Ltd. Pressure vessels which are used to solve hydraulically induced pulsation, vibration or rapid surge problems. Flowguard’s vessels can be found in a number of industrial sectors including Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Pulp & Paper, Waterworks. The same pressure pulsation dampening mechanism as described in the Cellular Suction Stabilizer apply to the combination dis-charge dampener. Combination dampeners have proven to be effective in preventing hydraulic resonance in discharge piping of Mud Pumps. Both types of dampeners reduce the residual pump flow variation.

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.)

1. 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.
2. Open bleeder valve ’A’.
3. Remove loading valve protector cap ’B’.
4. Remove cap from loading valve ’C’.
5. Loosen safety nut ’D’ three full turns.
6. 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).
7. Tighten safety nut ’D’ on loading valve ’C’.
8. Replace loading valve protector cap ’B’
9. Open suction valve. When air from bleeder valve ’A’ is evacuated, close bleeder valve ’A’.

1. Shut down pump and relieve line pressure.
2. Open bleeder valve ’A’.
3. Remove loading valve protector cap ’B’.
4. Remove cap from loading valve ’C’.
5. Loosen safety nut ’D’ three full turns.
6. 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).
   
7. Tighten safety nut ’D’ on loading valve ’C’ and replace cap.
8. Replace loading valve protector cap ’B’.
9. 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.

NEVER ATTEMPT TO CHARGE OR PRE-CHARGE A CARTRIDGE OUTSIDE OF THE PULSATION STABILIZER CASE.

FOR PROPER CHARGING PROCEDURES REFER TO THE SUCTION OR DISCHARGE CHARGING GUIDE.
