Direction of rotation
AxFlow Aturia NA series pumps rotate anti-clockwise when viewed from in front of the pump inlet
nozzle.
To confirm the direction of rotation (refer to the rotational arrow on the pump casing) use the following
procedure:
a.
Open the suction and discharge valves, allowing the pump to fill with liquid.
b.
Remove the coupling guard of a long-coupled pump, or the motor fan cover of a close-coupled
pump.
c.
`Bump' the motor by pressing the motor start and stop buttons in quick succession. If the
direction of rotation is incorrect, reverse any two of the three-phase power leads to the motor.
d.
After confirming correct rotation, replace the coupling guard or motor fan cover.
