4.2 IMPORTANT PROTECTIONS AND CAUTIONS
All products are designed with guards over their moving
parts. The manufacturer declines any responsibility in the
event of damages caused by the removal of said protec-
tions.
Each conductor or powered part is electrically insulated
with regards to earth. Extra security is also added by con-
necting the accessible conducting parts to an earth con-
ductor. This ensures that accessible parts cannot become
dangerous should the main insulation become faulty.
4.3 RESIDUAL RISKS FOR SURFACE PUMPS
Residual risks include the following:
a) The possibility of coming into contact (even if not accidentally) with the
motor’s cooling fan by inserting thin objects (e.g. screwdrivers, sticks and
similar) through the fan cover holes.
b) In electric pumps, possible restart without warning due to automatic re-
arming of the motor protection device, should the latter have been tripped
due to motor overheating.
5. HANDLING AND STORAGE
5.1 HANDLING
Apply established accident prevention regulations
Crushing hazard. The product may be heavy; use proper
lifting equipment and work apparel.
The following must be done when moving or dismantling the motor pump:
a) disconnect the electric supply;
b) remove the delivery and suction pipes (where present) if too long or
bulky;
c) if present, unscrew the screws that secure the motor-driven pump to its
supporting surface;
d) lift the motor-driven pump using equipment suitable to the pump weight
and dimensions (refer to the plate).
The product is packed horizontally in a cardboard box, with handles on re -
quest. If its weight and size demand it, it will be packed on a wooden pallet.
Handling the electric pump
To move the pump from its horizontal packed position, simply attach a suit -
able strap securely to the motor and lift it slowly with a hoist while checking
that the load remains balanced.
WARNING!
Check that the product is properly secured to the mo-
tor and that it cannot tip over or fall.
Handling the pump alone
Follow the same procedure as for the electric pump; in this case, the strap
must be attached to the motor mount.
5.2 STORAGE
a) The product must be stored in a covered and dry place, far away from
heat sources and protected against dirt and vibrations.
b) Protect the product against damp conditions, heat sources and me -
chanical damage.
c) Do not place heavy objects on the packaging.
d) The product must be stored at an ambient temperature b5°C
and +40°C (41°F – 104°F) with a relative humidity of 60%.
6. TECHNICAL-PRODUCTION CHARACTERISTICS
6.1. DESCRIPTION
Your product is a vertical multi-stage non-self-priming pump designed for
coupling to standard electric motors.
The abbreviations EVMS and EVM identify a wide range of vertical multi-
stage pumps with in-line ports, sized for nine nominal flow rates (EVMS 1, 3,
5, 10, 15 and 20 and EVM 32, 45, 64 m ³ /h), and a various number of
stages, designed to satisfy the most varied requirements for pressure; they
are available either as an electric pump (pump and motor) or pump alone.
The code identifying the models is described in Chap. 15.7 together with
the description of the rating plate.
If you have purchased a pump without motor, make sure your motor
is suited to coupling with the pump.
6.2 USE FOR WHICH PUMPS ARE DESIGNED
The pump is designed for:
- civil and industrial water distribution systems
- washing systems
- water treatment
- fire systems
- cooling systems
- pressurisation systems
- irrigation systems
6.2.1 USE OF DRINKING WATER
If the product is constructed with materials suited for pumping drinking wa -
ter, Before being used, the pump must be run with clean water at its nomi -
nal flow rate for the time indicated in the following table:
EVMS1 60 minutes ( minimum ) EVM32 15 minutes ( minimum )
EVMS3 60 minutes ( minimum ) EVM45 15 minutes ( minimum )
EVMS5 30 minutes ( minimum ) EVM64 15 minutes ( minimum )
EVMS10 30 minutes ( minimum )
EVMS15 15 minutes ( minimum )
EVMS20 15 minutes ( minimum )
6.3 USE FOR WHICH PUMPS ARE NOT DESIGNED
Improper use of the pump is hazardous and can result
in personal injury and damage to property
