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 fi 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 fi 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:
WARNING
(WARNING) Risk of damaging the pump or system
Risk of causing injury or damaging property

3. DESCRIPTION AND USE OF MOTOR-DRIVEN PUMP
3.1. DESCRIPTION
Description: MOTOR-DRIVEN SURFACE PUMPS
Type: CENTRIFUGAL
Model: CDX - CD -DWO – DWC-V - DWC-N,
2CD 2CDX (Dual-impeller),
CMA–CMB–CMC–CMD–CMR,
CDA (Dual-impeller)
3.2. USE FOR WHICH PUMPS ARE DESIGNED
These motor-driven pumps are suitable for pumping clean
water and other liquids compatible with stainless steel or cast
iron, namely:
CDX, 2CDX, CD, 2CD
Domestic water boosting, small-scale garden watering, wash-
ing, treatment of clean water in general (damp and salty envi-
ronments CD, 2CD).
DWO
- Washing vegetables, fi sh, shell fi sh and suchlike;
- washing and surface fi nishing systems for metal parts etc...
- washing systems for bottles, jars, glass containers, crates,
baskets etc...
- dishwashers, glasswashers, cup washers for communities,
hospitals and so on;
- end-of-cycle washing systems in a diversity of industries;
- spray booths;
- fl ood irrigation;
- handling, removal and transfer of liquids (including liquids
containing solids).
DWC
- chillers;
- cooling and heating systems;
- industrial liquid pumping.
CMA–CMB–CMC–CMD–CMR–CDA
They can be used to meet demands for low, medium and high deliv-
ery rates. Suitable for domestic, farming, commercial and industrial
uses, for the automatic distribution of water by means of small and
medium pressure vessel tanks, for sprinkler and fl ood irrigation, for
increasing mains water pressure in branch pipes, for complex ma-
chinery for industrial use.
Use the motor-driven pumps based on their technical speci fi cations.
3.3. USE FOR WHICH PUMPS ARE NOT DESIGNED
The pumps cannot be used to handle:
− dirty water or water with solids in suspension for (2)CD(X);
− water containing acids or bases, and corrosive liquids in
general (for cast iron pumps);
− water with a temperature over the temperature limit given in
chap. 4;
− seawater;
− fl ammable liquids and hazardous liquids in general.
The motor-driven pumps must never be made to work without
liquid.
