6.2 Design of the product

• Zeox FIRST H and V are horizontal and vertical high pressure non-self-priming pumps with
offline connection based on multistage design.
• Zeox FIRST H and V pumps combine use of both high efficiency hydraulics and motors.
• Zeox FIRST H pumps are equipped with double support bearing, assembled on a metallic
base frame with fully B3 standard motors. Cast iron coupling assure the motion transmis-
sion between driven and driving shaft equipped with shock absorbers against crashes and
torsional vibrations.
• Zeox FIRST V pumps are equipped with fully flanged standard motors.

7 Installation

7.1 Inspections before installation

Before installation of the pump, check that:
• The data mentioned on the identification plate of the product correspond to the submit-
ted order.
• The place of installation is well aerated, protected against weather inclemencies, and
must ensure environmental conditions according to the protection degree and the cool-
ing need of the electric motor.
NOTE:
For the installation of the product keep a free space above or behind the motor at least
equal to the height of the motor. This will allow a air circulation to ensure the correct
motor cooling and will be necessary for future maintenance, Before pipes connection
make sure that the rotating part of the pump rotates freely and is not hampered.
• The inlet of the pump is as much as possible near to the water to be pumped.
DANGER! Risk of death!
Check that implements (ropes, belts, chains etc.) and equipment (winch, crane, hoist,
gin, etc.) used for handling and lifting are well dimensioned to the weight, efficient and
complying with safety norms. See recommendations chapter 3.
• Verify water quality, temperature and eventual presence of sand, mud and dissolved gas.
• For Zeox FIRST H ensure proper anchorage of the base frame since eventual tensions or
deflections could modify the alignment of pump and motor. If necessary, shim it before
tightening definitively the anchoring bolts.
