6.2.4.4 Sand content
Make sure the maximum sand content of 50 g/m³ is not exceeded.
6.2.4.5 Temperature of the fluid handled
CAUTION
Excessive temperature of fluid pumped
Damage to the pump set, especially to the motor!
▷ Never operate the pump set at product temperatures exceeding those specified
in the data sheet or on the name plate.
▷ Increase the flow velocity past the motor.
The limits stated on the name plate or in the order documentation must not be
exceeded.
6.2.4.6 Flow velocity past the motor
To ensure sufficient cooling of the motor, the required flow velocity past the motor
must be observed.
For the required flow velocity v
This value must be met at all times by providing suitable installation conditions or
devices guiding the flow (e.g. cooling shroud, hood, etc).
The flow velocity past the motor is not defined. The heat is dissipated freely. This
heat dissipation must not be influenced or hindered by any structures, and a supply
of fresh water must be provided at all times.
▪ Example: pump set freely suspended in a vertical position inside a large tank
