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