noisy pump

[danny]

one of my pump is noisy.even if no hose is connected,it is still noisy.what's wrong with it?how can i fix it?it is a year old now,but it was noisy since it was only about 4month old with me.

If this is an air pump, your diaphram may be "stretched" and is vibrating against the side, pushing this down may help, although it may need replacement if available.

It also may be the rubber "hinge" that the arm the diaphram is mounted on is in poor shape which again will cause much vibration. This can sometimes be fixed by removing it and wrapping teflon tape around the rubber hinge and re-inserted.

My pumps are also noisy. Make sure your pump isn't rubbing up against something causing it to make noise. I have this same problem and move my pumps whenever I hear a louder than normal buzzing.

Also, what brand of pump is it? Some pumps are louder than others.

check the lil rubber feet. also....wrapping the pump in a towel helps alot

That's what I do too. I keep all my pumps on towels or soft surfaces. That helps a lot to keep the noise down.

I'm late to this thread Danny but the first thing to find out is if the pump itself is noisy or is the normal pump vibration causing the noise by contact with something else? (The latter is easy to fix using some form of dampening as others suggested while the first case may require you to open the pump up to repair it if it's worth the trouble.)

You can have all pumps from the same brand and only one is noisy, this is not all that uncommon, especially for lower end pumps.
You have received several great suggestions, I would consider them all or else simply replace this pump.
