2.9.4 Overheating
The following factors can result in the pump overheating:
• Excessive
pressure
on the delivery side.
•
Motor overload switch set incorrectly.
•
Ambient temperature which is too high.
Do not operate the pump with the valves closed, minimum
flow rate 10 % of Q
max
.
For pumps with a three-phase motor and no motor
protection, install an overload switch and set it correctly.
Do not exceed the permitted ambient temperature of 40 °C.
2.9.5 Pressure
surges
The pressure in the filter housing or pump housing (BADU Block)
must not exceed 2.5 bar or 3.0 bar for the Normblock. Otherwise
damage may occur to the acrylic glass lid or other pump parts.
Install a non-return valve.
The use of a frequency converter or a smooth start is
recommended in order to rule out pressure surges on the unit
side.
2.9.6 Blockages in the pump
Pieces of dirt in the suction line can clog and block the pump.
Do not operate the pump without a strainer basket.
Check how easily the pump rotates before starting it up and
after longer idle or storage periods.
Remove any impuritites from the suction line.
2.9.7 Drainage
An insufficient drain gap can damage the motor.
Do not block or seal the drain gap between the pump
housing and the motor.
Never assemble the unit with the motor positioned
underneath.
2.9.8 Risk of frost
Drain the pump/unit and pipes at risk of freezing in plenty of
time.
Remove the pump/unit during periods of frost and store it in a
dry room.
2.9.9 Water
temperature
The water temperature must not exceed 40 °C.
