Cooling

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.
