[Jameshong]

Hi all,

Currently, I'm using ehiem pump and find that it's a bit noisy(humming) so would like to know which brand of return pump is more quieter and price reasonable?

To: Mr Jameshong,

I had tried quite a number of Delivery Pumps between 600 ltrs/hr to 2300 ltrs/hr for the past of my Fish Tanks. And in my opinion, I will still prefered New Jet Pump, consider the Price, Efficient and Power. Also, I don't feel any noise in Submerged in Tank.

For your info, my present New 1.5 Ft Cube Tank, I had changed to New Jet 2300 (Italy Make), - is Adjustable from 1000 to 2300 Ltrs/hrs and Power is own 38 Watts. And price is less then Sgd 110.00.

For your info, please.

Thks/rgds.

Hi bro, juz curious, im using a 1264 and it was completely quiet, so u might wanna check if ur pump is faulty?

for value in price, reliability and electric consumption, u can consider using rio pumps...i haf used a rio 14 for my chiller return and rio 20 for my beckett, sound wise is quite ok for me...HTH

How about new Reef octopus. I just replace my faulty OR6500 with Reef Octopus 7000.

Compare to Eheim 1262 (I running both for return pump) it equaly quite and it rate only 88W ( lower than 1262).

eheim shouldn't be noisy perhaps you might want to give it a vinegar bath? the bath helped to quieten down my sicce pump.

or just like me, you could wait for tunze silence to reach singapore

i tried Ehiem Pump submerged and unsubmerged before.

Submerged - no sound at all.

Unsubmerged - yes, sound created by the vibration from pump in-touch with my cabinet base.

Hi all,

My 1262 is just newly purchased so I doubt it's defected.

btw, may it be the elbow of the piping restricted the flow hence causes vibration and hamming sound?

I was suggested by tank maker to use soft piping from 1262 to PVC piping w/o elbow for return so before I try it ...would like to know anyone tried before with good result ?

pls advice.

Good AM Mr Jameshong,

Correct me if I am wrong.

If your New Pump have Humming Sound, there's could be the Motor is still not Stable (Run In) yet, it is not Air Pocket, you can hear or feel it more Clearly when placing the Pump Outside the Tank (Dry Method). Let it Run for few more day and do not Throttle the Inlet and Outlet Flow. It should go away few days later.

It is ok to use Flexible Hose on the Outlet Side but try not to use on the Suction side.

Elbow is not ideally go for Outlet as it will create Some Back Pressure which may cause some Heavy/Over Load on the pump. If need to, try avoid Straight 90 Deg Elbow, you can find those Smooth Curve Elbow (Green Color) from any Accesory Fish Shop. And try to Shorten the Length on the Outlet Hose or Pipe.

If you place the Pump in Dry Method, try to place it atleast 0.5 mtr lower than the Tank for Better/Easy Gravity Suction.

yeap nice pumps will need to have a break in period. if i'm not wrong its when the plastic and metal parts loses its chemical coating and it starts to slime up from your tank. after which it would quieten down alot. give it a week or two to run

Hi bro,

your tank maker may be right, in order to reduce vibration sound, it is always best not to connect pumps directly to hard pipings but rather to have a small section of soft tube in between to absorb any vibrations.

You can further reduce vibration if you do not place the pump directly onto the tank floor but use the rubber sucker provided.

Hope that helps.

Hi bro,

I have already placed a japan mat underneath the pump to absorb vibration but still heard some humming sound especially nite time. Beside rubber sucker and soft tube, are there any other solution ?

Got pic? Your pump new or used?

[hahaha]

Hi Gouldian, He mentioned its new..

To TS,

BTW, I am using soft piping from pump outlet to the PVC pipe.

So far so good. A BIG advantages I feel of using this section of soft piping is that my pump can be "off" position a bit without causing stress in the PVC pipe joints which might cause leak in future.

Even though my pump is submerged in-sump, just don't like the thoughts of the joints leaking.

New. Bought from C328.

Hi bro,

I may try it if the humming sound do not reduce significantly after 2 weeks break in period.

Thanks.
