Conic sealing pads

The SKH pumps are equipped with 4 conic steel pads to
be used in correspondence with the pump's delivery ports
(see Fig. 5) or in the optional fitting flanges. Their function is
to guarantee the sealing of the connection. The seat of the
pump's delivery port is already machined in order to hold the
conic pad; if it were necessary to make the connection for
the delivery fitting or the closing plug they must be specially
machined as indicated in Fig. 5/a.
At each disassembly, the conic pads must be
replaced.
