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.
