Konus Burners, Primary, and Vat Pumps
In the emergency operation, the No. 3WV valve will port all of the oil
that is supplied by the vat pump back to the Konus burner. The No.
2WV valve will be closed in the emergency operation. Please refer to
the “Isolation and Change Out Procedure” for the sequence of
changing the specific pump.
VSF1 - VSF2 Suction Filters
These filters will remove contamination from the oil prior to being
ported to the suction port of the operating vat pump. If the specific
filter were to become contaminated then cavitation of the pump can
occur. These filters should be cleaned or changed on a regular basis.
