Checking The Direction Of Rotation - SFA Sanipump VX 50 Bedienungs- Und Installationsanleitung

5 Installation at Site
Resonances Any resonances at the usual excitation frequencies (1 x and 2 x rotational frequency,
vane passing frequency) must be prevented both in the foundation and in the
connected piping, as such frequencies may cause extreme vibrations.
1. Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.

5.2.2 Checking the direction of rotation

WARNING
Hands or foreign objects in the pump casing
Risk of injuries, damage to the pump!
▷ Never insert your hands or any other objects into the pump.
▷ Check that the inside of the pump is free from any foreign objects.
▷ Take suitable precautions (e.g. wear safety goggles).
ü The pump set is connected to the power supply.
ü Pump sets with three-phase motor: Check the direction of rotation via the
reactive force generated by the motor torque.
1. Hold the pump by the handle.
2. Start up the pump for a short period (5 seconds max.).
A reactive force in anti-clockwise direction must be felt.
3. If the impeller is running in the wrong direction of rotation, check the electrical
connection of the pump in the control system.
4. Disconnect the pump set from the power supply again and make sure it cannot
be switched on unintentionally.
5.3 Installing the pump set
Always observe the general arrangement drawing/outline drawing when installing
the pump set.

Fig. 4: Fastening the duckfoot bend
1. Position duckfoot bend 72-1 on the floor of the tank/sump.
2. Insert chemical anchors 90-3.38.
3. Bolt duckfoot bend 72-1 to the floor with chemical anchors 90-3.38.
