Impeller blades are like fans, whether that is on a helicopter or a ceiling fan. They must be perfectly balanced to work effectively or else when something unbalanced rotates on it's shaft you get vibes produced. Also an unbalanced impeller will grind at the shaft it spins on - not good!SuperColey1 said:I may try this with the cheap Â£5 pumps that Wilko sell and stick it over my diffusor. If it wears out as per previous post the I can buy another at that price.
I would of course put the 1mm hoels in the impellor blades as per another users comments on the thread.
Good find Garuf
This is a silly statement. Its like saying they wouldn't make CO2 reactors if you could make your own or they wouldn't sell branded filter film if you could just cust out the shapes from pond filter foam or they wouldn't make off the shelf ferts if you could make your own or they wouldn't sell Nutrafins if you could make a DIY. All of which we all know we can.Deltec and other companies wouldn't be bothering to make needle wheel impellers if we can DIY it ourselves you know.
