7 Servicing/inspection
NOTE
Paraffin oil is bright and transparent in appearance. A slight discolouration, caused
by the running-in process of new mechanical seals or small amounts of leakage
from the fluid handled, has no detrimental effect. However, if the coolant is
severely contaminated by the fluid handled, this suggests a defect at the
mechanical seals.
ü The suction cover and the impeller have been removed.
1. Place a suitable container under the pump set.
2. Slide mechanical seal 433.02 along the shaft.
3. Drain the oil.
1. Fill 0.10 litres of oil (for impeller type VX) through the opening between the
stationary assembly of mechanical seal 433.02 and rotor 818.
2. Thoroughly clean rotor 818 and the contact face of the stationary assembly of
mechanical seal 433.02. Remove any oil residues.
3. Fit the rotating assembly of mechanical seal 433.02.
4. Fit impeller 230 and suction cover 162. Observe the tightening torques.
