OPERATING AND MAINTENANCE MANUAL PART 2
THE USER SHOULD KEEP THIS DOCUMENT
1. INTRODUCTION
This instruction manual is split into two booklets: PART 1, con-
taining general information regarding our whole product range;
and PART 2, containing information speci c to the motor-driven
pump you have purchased. The two publications are comple-
mentary to each other, so make sure you have both.
Comply with the instructions contained in them to get the most
out of your motor-driven pump and assure its proper operation.
If you need further information, get in touch with your nearest
authorized dealer.
If information in the two parts contradict each other, take PART
2 containing the product’s speci c information as valid.
NO PART OF THESE ILLUSTRATIONS AND/OR TEXT MAY BE
REPRODUCED FOR ANY REASON.
The following symbols have been used in the compilation of this
instruction booklet:

The motor-driven pumps are employed to handle cold and hot
water (see chap. 4) and are used in permanent installations.
They are built with materials assuring long life and consistent
performance if used according to the instructions given in Part
1 and 2 of the manual.
Their special construction means they can be disassembled to
service the motor and replace the impeller and mechanical seal
without having to disconnect the pump casing from the suction
and delivery lines. They are designed for medium and high deli-
very rates in conformity with EN 733 DIN 24255 standards and
other corresponding European standards.
3.2. USE FOR WHICH PUMPS ARE DESIGNED
The motor-driven pumps can be used for the following applica-
tions:
RESIDENTIAL AND COMMERCIAL: water lifting, pressure boosting
systems, air-conditioning, cooling.
FARMING: sprinkler or ood irrigation.
INDUSTRIAL: water handling, washing plants, transfer of mode-
rately aggressive liquids compatible with AISI 304/316 steel for
3/3L-series models.
Use the motor-driven pump based on its technical speci cations
.
3.3. USE FOR WHICH PUMPS ARE NOT DESIGNED
Series-3 and MD motor-driven pumps cannot be used to handle
dirty water, water containing acids and corrosive liquids in general,
water with temperatures higher than those mentioned in chap. 4,
saltwater, ammable liquids and hazardous liquids in general.
The motor-driven pumps must never be made to work without
liquid.
