Danger!
Air bubbles or accumulations of gas
around the mechanical seal create a
potentially fatal explosive atmosphere.
Provide a constant supply of pumped
media to the supply and pressure pipes
as well as to the interior of the pump
that is in contact with the liquid.
Provide appropriate monitoring
measures to ensure this.
1.4.5 Drive
A three-phase squirrel-cage motor drives the pump. The
motor is cooled by the dissipation of heat from the cooling
fins to the surrounding air.
Important!
Observe the limit temperatures specified in section 1.4.7
‘General data’.
The exact motor data can be found on the name plate.
Caution!
Impermissible heating will damage the
three-phase motor.
Comply with the voltage tolerance of
± 5% according to DIN EN 60034-1.
In standard motors (with no explosion
protection) a tolerance of ± 5% also
applies for the voltage range.

1.4.6 Dimensions, weights, performance data
The measurements, installation dimensions and weight de-
tails can be found in section 5.2 ‘Dimensions’. The instruction
documents and the name plate data specify the performance
and connection data of the respective pump type.
Performance verification of the pumps is carried out accor-
ding to DIN EN ISO 9906 (Rotodynamic pumps - Hydraulic
performance acceptance tests), Class 2.
