What is an asynchronous pump?
Asynchronous motors adjust to the electrical current that is given to them. Like a light on a dimmer switch. Apart from the obvious advantage of being able to adjust the pump to suit your requirements, there are a lot of other advantages like:
Power saving
Increase in life span
Less maintenance
Avoiding shock loading
Soft starting
Decrease in in-rush current during starting
Safety
In most of the cases, the variable speed control is achieved by incorporation of external devices like auto-transformers, variable resistors, regulators, Variable frequency drives etc.

Ah, that explains the video showing the rheostat.
Anyone have personal experience with them? Like them? Don't?
ADDY, what pump do you use? [Was showing your "fish cam" video to hubby last night.]

I have four pumps, currently run the pond with an evolution series pump. I have two dragon lim pumps being shipped to me from arizona. I will use one of them next summer.
