This model has the same structure of models 25-30-35-40 but to disassemble and assemble the lip seal you do not have to remove the inter-
nal back part.
- Put the pump body (ref. 10) assembled with its internal back part (ref. 65) on a flat surface (ill. 24);
- hit the lip seal (ref. 67) using a round bar with proper dimensions;
- turn the pump body round (ill. 25);
- take the new lip seal and put it on the mouth of its housing with the correct orientation (the spring must be turned towards the pump inside);
- insert the lip seal into its housing using a round bar with proper dimensions and a hammer.

5.5.4 - MECHANICAL SEAL REPLACEMENT

- Disassemble the pump without removing the pump body (for the models type 20, remove also the pump body (ref. 10) from the
counterflange (ref. 5);
- (models with the component parts shown in ill. 4A) through suitable pincers, remove the seal snap ring (ref. 9A);
- (models with the component parts shown in ill. 4B) through a suitable wrench, unscrew the three screws of the seal shaft collar (ref.
9B) and remove it from the shaft (for the models different from types 20, it is necessary to insert the wrench through the hose of the
pump body;
- remove the seal washer (ref. 14) when present, then the rotating part of the seal (ref. 67A), then the fixed part of the seal (ref.
67B), then the rubber gasket (ref. 67C);
- take a new mechanical seal, separate the rubber gasket from the fixed part, clean the lapped races of the rotating part and of the
fixed part with a soft cloth, remove grease from the seal housing in the pump body and from the shaft, lubricate the rubber parts with
water and soap;
- insert first the rubber gasket in the pump body, then the fixed part of the seal;
- insert the rotating part of the seal being careful not to cut its rubber parts when they cross cutting parts;
- (models with the component parts shown in ill. 4A) insert the seal washer and, pushing the spring of the rotating part, insert the
snap ring in its housing.
- (models with the component parts shown in ill. 4B) insert the seal washer (when present) and the seal shaft collar; while keeping
the seal shaft collar pressed against the other parts of the mechanical seal (for example through a pipe), tighten its screws, remem-
bering that, when assembling is completed, the axial lenght of the rotating part must be between 13 and 14 mm.

5.6 - BRUSH REPLACEMENT

In the models with direct current motor the brushes (ref. 7) are sliding contacts subject to continuous wear during operation; the wear
depends on the real value of the voltage; a brush is completely worn when the spring pushing it against the commutator is at limit
stop; when the brushes are getting completely worn, you can notice an irregular behaviour of the motor; to replace them:
- remove the fan cover (ref. 2);
- remove the screws on the brush bearing (ref. 6) that connect the brushes to the motor windings;
- remove the brushes, lifting the springs that push them against the commutator, replace and screw them;
- reinstall the fan cover;
