Controlling Iwaki Pump Flow?

[Zuiplap]

Hello Gentlemen,
Greetings from the U.K!

I found your forum via Google whilst searching for information on Iwaki pumps when used in home brew applications ...you guys seem to use them more than any other community.

So, I have a quick question please... has anyone tried controlling the flow of these pumps (MD-10 specifically) using a variable AC/Mains voltage?

Many thanks in advance!

These magnet driven centrifugal pumps can be controlled easily by squeezing the outflow tube.
This will do no harm to the pump and if you use a tap/faucet, regulation can also be quite precise.
