3ES X
The motor-driven pumps are employed to handle cold and hot water
(see section 4) and are used in permanent installations. They are built
with materials assuring long life and consistent performance if used
ac- cording 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 low and medium delivery 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 applications:
RESIDENTIAL AND COMMERCIAL: General water supply, water

Description
Inline End suction close coupled cast iron pump
Inline End suction close coupled with flanged
motors and rigid coupling
lifting, swimming pool, pressure boosting systems, air-conditioning,
cooling.
FARMING: sprinkler or flood irrigation.
INDUSTRIAL: water handling, Chilling unit, Boiler, Heat Exchanger,
coolant unit.
Use the motor-driven pump based on its technical specifications.
3.3 USE FOR WHICH PUMPS ARE NOT DESIGNED
3E inline motor-driven pumps cannot be used to handle dirty water,
water containing acids and corrosive liquids in general, water with tem-
peratures higher than those mentioned in section 4, saltwater, flamma-
ble liquids and hazardous liquids in general.
The motor-driven pumps must never be made to work without
liquid.
