I cleaned it yesterday and now it sounds like a jumbo jet..........

Ripped it to pieces 10plus times...... its driving me nuts...

anyone got any ideas..... cheers

What model

Turbo 1250?

MCE600 external. Had to turn it off all last night..... man its loud

Yoinks... have you tried some filter wool under the pump?

Other thing to try, is take the pump out, submerse it in the tank and turn it on, make sure it's totally silent just pumping water (i.e. the impellor/needlewheel isn't loose on the shaft). If that's all quiet, you just have a vibration issue, which should be findable without too much trouble by pressing on different parts of the plastic and seeing if it goes away.

you could try pulling it apart again . removed the needle pin wheel assembly .repacked the rubber bush assembly with vaseline and re-assemble . also rubber sponge under the pump could help .

contact Deltec for some replacement bushes and damping kit .

Try covering the venturi hose with your finger and see if that stops the noise. Since that's the only thing that might make a loud whine like a 747 sounds like when it's landing. From the ground anyway, otherwise they're usually pretty quiet.

Cover the air intake hose on a needle wheel pump and it will whine even more, from cavitation on the needles.

No it doesn't. The pump sound from the pump doesn't change at all and the whistling from the valve on the venturi disappears(Obviously)

The ehiems on the 902's make a real racket when you block the air supply.

Maybe the pumps on the smaller models aren't powerful enough to cause any significant cavitation?

on the 701 to

:oops: :oops: same pumps doh :oops: :oops:

hell yes, first thing i noticed when i turned mine on!

Vasoline worked for about 4 hours (was as silent as a church mouse.

Any other ideas for lube. (i'm going to here about it now..... what for slappers response )

i pushed the keyboard away for ten minutes

and now i am lost for words raeh1

:lol:

Deltec just sent me some parts to help reduce the noise on the mce600, please pm me address and i will post the parts to hobbyist with mce600

Free or do we have to pay?
