LINES OF LUBRICATION FEEDING
When flushing lines are present, open the feeding system and adjust the medium according to quantity/pressure stated
in the A APPENDIX.
In case of failure or lack of flushing, pump running can be affected irreparably.
7.5.
ROTATION DIRECTION TEST
In case of disassembled motor, it’s mandatory to check rotation direction BEFORE mounting it to the pump:
ATTENTION!
Comply with safety descriptions listed in the “POWER CONNECTION” paragraph.
Motor rotation mut be clockwise, looking from fan side. In case of wrong rotation, invert the phases properly.
In case of pump equipped with motor, follow the instructions underneath to check the rotation direction:
STEP
ACTION
1
Start the pump for an instant with the discharge gate valve slightly open (20% opening).
2
Make sure the rotation’s direction is the one shown by the arrow on the lantern: if it rotates the opposite
way, swap the connections of two phases.
7.6.
COUPLING ASSEMBLY
When the pump is not equipped with motor, half couplings can be mounted on the motor shaft and pump shaft.
Follow the instructions underneath to assemble the motor properly:
STEP
ACTION
1
Lightly lubricate coupling’elastomers with liquid soap, Vaseline or silicon oils.
2
Put the motor on the lantern flange, by fixing it with the bolts.
3
Check the half couplings are fitted without forcing them. Otherwise remove the motor and repeat the
operation.
In case of problems, get in touch with Salvatore Robuschi & C s.r.l. Technical Dept.
4
Check the distance between the two half-couplings is 3÷ 5 mm
5
Tighten the motor fixing bolts
3÷5 mm
