Energy Savings

Engine Speed
The higher the frequency (Hz), the higher the motor rotation speed (rpm). In 2-pole motors the speed is approximately [frequency x 60]:
- 30 Hz ~ 1800 rpm
- 40 Hz ~ 2400 rpm
- 50 Hz ~ 3000 rpm

The flow rate is proportional to the speed.
Pressure is proportional to the square of the velocity.
Power is proportional to the cube of speed.

For example, if we reduce the speed by 30%, the new parameters will be:
Flow rate ~ 70% of the original
Head height ~ 49% of original
Power ~34% of original
