Instructions for disassembly
N.B.:
The tools used to disassemble the valve seats are NOT supplied in the maintenance kit. The
nuts on the head must be tightened to the torques indicated in SHEET 00[c] using a torque
wrench (not supplied).
To remove the suction seats, simply remove the lower flanges.
To remove the delivery seats, you can use the extractor supplied.
Alternatively, for disassembling the delivery seats, suitable equipment must be prepared (this may
be supplied on request by GEA Niro Soavi S.p.A. ) to carry out the work as specified below, referring
to Figure 7-23:
- remove the upper and lower flanges
- move the pumping piston back to bottom dead centre
- remove the seat of the suction valve (6)
- to remove the seat of the delivery valve (1) use a rod made of soft metal, such as bronze or
aluminium: insert the rod in the head through the orifice in the suction valve; the rod diameter
must be as large as possible, and to improve its contact with the seat it is possible to make a
conical support as the bottom part of the seat
- tap on the rod with a hammer until the seat is removed
