Line connection to any of the two ports is indifferent for
proper pump functioning. The unused ports must be
hermetically closed.

Conic sealing pads

The VK 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 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.
