GENERAL WARNINGS
1. Pump disassembly and reassembly require some basic operations and use of tools found
in most workshops.
NOTE : The pump’s component parts are modular and therefore fully interchangeable.
Whenever parts have to replaced, please specify in the order:
• Pump type;
• Serial number (marked on pump identification plate);
• Reference number on the detailed diagram, name and part number as indicated on
the spare parts and accessories list (section 5.2 of this manual).
To simplify maintenance work, two kits have been devised. The Gaskets Kit, containing
all the gaskets recommended for substitution after disassembly of the pump and the
most commonly used removable parts. You are advised to keep this kit in a dry room,
away from heat and light (sun and UV rays) in order to prevent hardening of the
elastomer parts.
The Maintenance Kit, including, as well as the Gaskets Kit, the 1st and 2nd stage vanes
and other parts that it may be necessary to replace when overhauling the pump
completely. These parts have a life of approx. two years under conditions of normal
operation.

2. Before reassembling the pump, all parts must be cleaned thoroughly with a soap and
water solution and rinsed with demineralized water.
CAUTION : Particular care must be taken in cleaning the lubrication ducts and oil
passage nozzles, which must always be kept free of impurities.
CAUTION : Take care that the soap and water solution does not remain in the various
cavities and recesses of the pump, in the blind holes in particular.
3. Then dry the parts, by heating where possible but without using compressed air (it
generally contains polluting substances), taking care not to exceed a temperature of 80
°C.
4. The sequence of reassembly is the inverse of the disassembly operation. Take the same
precautions:
• Spread some clean oil of the same type as used to lubricate the pump over the
different parts, in particular the inner lip of the oil seal, the bearings and vanes.
• If the oil seal has no inner dust-block lip, 2/3 fill the area between the two lips with
grease.
CAUTION : Do not allow the grease into the area of the circumferential spring.
• Lock without forcing the nuts on the four tie-rods (44) connecting the parts of the
pump block. Before locking, check that all parts are touching as required.
