Pressurizing the pulsation dampener
CAUTION
Do not pressurize the pulsation dampener if it is not built into the pipe system. Con
sider the maximum operating pressure. Exceeding the maximum operating pressure may
lead to serious injuries or damage to the pump and the environment.
CAUTION
Consider the filling medium for the pulsation dampener housing – in this case com
pressed air or nitrogen. If in doubt concerning the correct filling medium for your
pulsa tion dampener, contact your Albin Pumps representative for assistance.
Pressurize the vessel to approximately 85% of the actual working pressure of the hose
pump. Then fine-tune the pressure until optimal dampening is reached.
1. Shut the ball valve (pos. 17) on the pulsation dampener.
2. Connect the filling medium to the filling nipple.
3. Apply pressure to the pulsation dampener by the filling medium.
4. Open the ball valve (pos. 17) gently. Filling medium will now enter and pressurize the
vessel. Check the pressure gauge (pos. 20) for the actual pressure inside the vessel.
5. Pressurize the vessel to approximately 85% of the actual working pressure of the hose
pump.
6. When the required pressure is reached, shut off the ball valve (pos. 17). If the vessel is
pressurized over the maximum allowable working pressure, the pressure-relief valve will
open automatically.
7. Leave the pulsation dampener pressurized for at least 20 minutes. If the pressure has
dropped, check the pulsation dampener for any leakage or see paragraph
“Troubleshooting” for solving the problem.
CAUTION
If you want to check the function of the pressure-relief valve, apply pressure to the
vessel just over the maximum working pressure. The valve should automatically open. If
not, do not apply more than 1000 kPa (10 bar) to the vessel, relieve the pressure and
replace the pressure-relief valve.
8. Fine-tune the pulsation dampener, by adjusting the pressure inside the vessel while
the pump is running, to an optimal dampening.
