     Avoid, at all times, a pressure higher than the maximum operating pressure.  When using a Bredel series 265-2100 pump with pulsations over 500 kPa (5 bar, 72.5 psi) use two pulsation dampers - one for each pump head.

     Avoid too heavy loads on the flanges. The maximum forces are given in the table below: Maximum flange loads Force Unit PD/40 PD/65 PD/100 1000 1400 2000 1000 Lifting and moving the pulsation damper To lift, move and position the pulsation damper, suitable hoisting belts must be used. The best place to attach the hoisting belts is immediately behind both flanges of the pulsation damper.
  • Page 13 Consider the filling medium for the pulsation damper housing – in this case compressed air or nitrogen. If in doubt concerning the correct filling medium for your pulsation damper, contact your Bredel representative for assistance. CAUTION Before pressurizing the pulsation damper ensure that the pulsation damper is built in the piping system, ensure that the suction and discharge valves are op en, ensure that any drain valves are closed.
  • Page 14: Maintenance

    6 Maintenance Careful maintenance and, in particular, scrupulous cleaning are essential for problem-free operation of the pulsation damper.  Before carrying out any maintenance to the pulsation damper, please thoroughly acquaint yourself with the directives in the chapter 2 SAFETY. ...
  • Page 15: Replacing The Pulsation Damper Hose

    Support the pulsation damper in such a way that it cannot fall during disassembly. Remove the mounting bolts from both flanges. Lift the pulsation damper onto a suitable workbench. Adhere to the instructions for lifting and moving as mentioned in paragraph 5.4 Lifting and moving the pulsation damper.

    15. Pressurize the vessel to 1400 kPa (14 bar, 203 psi) above atmospheric. By pressurizing the hose will be stretched outwards, forcing the hose ends over the inserts. 16. Close the ball valve. Tighten both hose clamps (pos. 8) with the proper torque values. The minimum required torque values as advised (see paragraph 8.2 Torque values) cannot always be realized in the field.
