CHECKING AND CHANGING THE SEALING OIL
FEKA VS-VX
To perform this operation, slacken the six screws (45) so as to be able to remove the
strainer cover , the strainer and the pump body (1). Retain the O-ring (28) and the nuts
(51). Using a suitable spanner, unscrew the impeller retaining nut (18), holding the
impeller (4) still with your hand. Retain the key (17) and the sand guard (15). Now
overturn the pump with the hydraulic part facing upwards, unscrew and remove the
drainage cap (64).
Tilt the pump so as to let the oil flow out of the drainage hole (64) and catch it in a
container. Analyse the oil: if you find any particles of water or abrasive materials (for
example, sand) it is advisable to check the condition of the mechanical seal (16) and to
have it changed if necessary (at a specialized centre). In this case change the oil too,
with
about 170 gr of oil type MARCOL 152ESSO
.
Top up the oil level inside the sealing oil chamber using a special funnel inserted in the
hole in the cap (64). Screw the drainage cap (64) back on and perform the disassembly
operations in inverse order to reassemble the pump after having spread a suitable
amount of teflon grease in the seat of the sand guard (15).
OLD OIL MUST BE DISPOSED OF AS REQUIRED BY THE REGULATIONS
IN FORCE.
