Disassemble the suction and outlet valve units, screwing a sufficiently long M8 screw in such a way as to be
able to reach the valve plate and extract the valve guide from the seat, 1, fig. 22. If the M8 threaded holes
should not be present on the valve guide, dismantling can be easily carried out by leveraging with simple
tools (fig. 23).

pump activity), operate as follows:
