Cooling
Figure 07 - Pump cooling
The pump is cooled by forward curved fan located within the coupling housing. This provides air flow
around the pump to aid cooling. The cooling fins also radiate the heat away and the motor fan cools the
drive motor.
The gearbox oil is cooled down by recirculation and convection from the fan.
In many cases the process gas can also cool the element.
