Changing diaphrams in air pumps

[Ben]

Hi crew,
Just wondered if anyone puts in new diaphrams in old/used air pumps?
I have a couple of basic air pumps and they have lost the capacity to make air.
I have not done it before…any pointers?

Cheers,
Ben

yeah always used to do it the trick is not to bend the metal rod and not to turn the nut on too tight to the diaphram. Because it moves on magnetic force if you bend the rod it wont pump air properly... If you need help youve got my number....

cheers mate! one thing though....
when buying the rubber diaphrams are they all the same? one size fits all?
i have 3 pumps thats are out of service at the moment.

no sometimes they are different sizes just take the name and model number down and go to your lfs they should stock them. mine does!!!

cheers again!
I will do that!
that will give me a few extra air pumps up my sleave! maybe a few more tanks!
