11.1 Changing the bellows
At every maintenance work at the plunger seal assembly or after 4000 operating hours or at least once in a year
the bellows needs to be changed. The mounting clips should also be changed (damaged during removal). Proceed
as follows:
 Loosen the plunger from the piston rod (refer
to the chapter ‚seal assembly‘).
 Use end cut pliers to loosen or snap the hose
clamps (180 und 190). i.e. place the pliers on
the latch joint (A) of the clamp and squeeze
strongly or squeeze and twist.
 Pull down on the bellows (200)
 Use a 60 mm A/F spanner to unscrew the
piston rod (170) and remove it together with
the bellow (200) from the pump intermediate
chamber.
 Take the bellow off the piston rod.
 Slide a new bellow onto the piston rod.
 Fig. Bellows
 Loosely slide the hose clamp (190) over the bellow (for later assembly).
 Lay the hose clamp (180) on the crosshead/pump housing (for later assembly).
 Use the 60 mm A/F spanner to screw the piston rod with bellow into the crosshead and tighten to 150 Nm.
 Pull down the bellow and fit over the cylinder bush ensuring that it is not turned into itself. (cast seams should
be vertical).
 Adjust and fasten the hose clamps (180 und 190). The latch joints (A) on both hose clamps must be carefully
compressed with end cut pliers or similar. Ensure that the bellow is seated correctly.
 Connect the plunger to the piston rod as described in ‚Plunger seal assembly’. Repeat the procedure for the
remaining bellows and refit the intermediate chamber cover plates.
Each time you replace the bellows check the surface of each crosshead bore for
signs of corrosion.
Report any signs of corrosion to HAMMELMANN immediately.
