JEBAO Pumps ?

Post by Admin on Sat Apr 02, 2011 10:56 pm

Having recently "Killed" yet another Pond Pump Rolling Eyes I was toying with buying one of these > http://cgi.ebay.co.uk/Jebao-4500gph-Land-Amphibious-Pump-Koi-Fish-Pond-/320570264151?pt=LH_DefaultDomain_0&hash=item4aa37a0a57

Jebao is a "Good" Brand I`m told Very Happy and Eco-Friendly ie (inexpensive to run ) but I can`t seem to find a UK oulet for them Question

What say You Guys ? Do you know anyone running them or of a retailer for these in the UK ..

a friend of mine asked me to do a trial of a 16000 for him , to which i agreed. he bought it from ebay. and dropped it off at mine.

i thought i would do a direct swap with a aquamax pump i had running of the same turnover on a compression filter. after swapping over the pumps intially i had to tighten all my clips and jubilee clips up as it burst the pipes off easily. which said to me this pump has more power than my aquamax. so i put it onto my Bakki Shower and replaced the 16000 aquamax that i had on there. it run quite happily for three months on my shower without any fail. i then took it off and gave the pump back to my mate.

Was the "Ebay"Seller in the UK Sweetie ?

I have just mailed > http://www.jebao.com/english/displayproduct.php?proid=50805 for a "Price List" in a bid to determine whether it would be less expensive for them to ship a Pump to me from there in comparison with the Ebay Seller in the US Rolling Eyes

Sorry Missed this one DIY DID Very Happy

I have not had any experience with them but Miss Bindi swears by them and I would say thats a good enough recomendation for me with the amount af ponds she is running.

I`ve just emailed an ebay seller who has the Jebao "Sump" Pump for sale Sweetie Very Happy Just in case It might have been he who sold the other Models we are after previously ?

The 4,500 GPH equates to 20,000 lph Lau ...
Answer: 4500 gal(UK) = 20457.405 L


I doubt my Giant TT could handle that phlow though as it could not cope with a 12,000 lph Sequence ..... Rolling Eyes

best price i got from a UK company. delivered price is a tenner dearer.

the concern i have as with buying anything from the states is that you pay the airport tax when it gets delivered which has been in the past £40. work out expensive then!!

Hello

I worked extensively with Jebao pumps in the marine industry and they were of the rubber impellor type. and were of the positive displacement type. This means they were fantastic at self priming and pumping to great heads, so much so that somewhere in the system it was normal to have a relief valve fitted. However this great turn over came at a price. They are expensive to run the greater the head the greater the cost to displace the same volume of water. In other words Positive dispalcement. Unlike an impellor of the cetrifugal type whereby the greater thehead the less water flow and reduced power. Having said all this. Looking at the picture I cannot see wether this pump is infact a rubber type impelleor with fan like teeth or of the impellor type.

Please check the power rating agaist head & flow rate before buying.

Best Regards Dave

Hi Mio looks good on paper, however at electricity being charged @ 13p per Kwh this pump would cost you £800 per anum to run 24/7

The spec sound good, but there are still only two types of basic design.I am pretty sure looking at the head, this vortex is infact a centrifugal type , however with a close fitted impellor this would give higher flow rates at higher back pressure( larger heads) but hence the high cost.

The max flow rate of this powerful and energy efficiency magnetic drive pumps is 4500 gallon per hour @1FT. These versatile pumps can be used submerged or inline, positioned horizontally or vertically, to drive larger waterfalls, larger pond filtration systems, or any other pond installation. Uses only a fraction of the energy of comparable models. This pumps come with a female coupling to adapt to standard pipe thread fittings.

Features:

Designed specifically for large pond installations including waterfalls and pond filtration
Land amphibious pump
Dimensions: 9.8"(L) x 5.7"(W) x 6.7"(H)
Power Cord Length (feet) : 33

Mio A true centrifugal pump( including sequence) only has the ability to self prime more than the suction throat( a few inches)and has to be fitted with an air pump ( which is infact a positive disaplacement pump) This would only add to the cost of manufacture and on a small scale is not worth it. However it would be possible to fit a P.D. type pump ie piston, screw, scroll type pump on a timer for a few seconds on the same system to create a negative head( vacume) then switch on the cetrifugal pump. This would then prime. An other way is to install a non return valve in the suction line, preventing the line from draining when the pump is stopped. Therefore primed when restarting. To initially prime the pump it is necessary to fill the suction line from waterline to pump outlet to ensure priming occurs. This is usually done with the aid of another person, if non return valve is not fiited by holding hand over bottom of suction pipe( granted not always easy) and then filling the line via the discharge pipe. I am sure you get the idea and I am sure there are a number of ingenous ways of doing this.

The wretched RPBD is the problem Dave Rolling Eyes

It won`t stay primed at water level so the Sequence is on the Ground atm Rolling Eyes

Mio

Cetrifugal pumps of the open end impellor type are fantastic at transfering large quantities of medium at low discharge heads and positive suction heads( continually primed) However even in a situation as this any leaks however small on the suction side will draw in air, or any other means of producing vapour will cause loss of pumping seal( pump will gas up) I am not saying this is what is happening in your situation but can happen.Pumps once primed may cavitate when pumping with any vacume. That is water or any media will vaporise when at low temps under conditions such pumping from large suction heads ( you can simulate this by shuting in a suction valve)So water already at saturation with air could easly change state (vapor) under the right conditions.

Just to give you an idea, cavitation occurs to ships propeller( Just a pump really) when vessels are in ballast( high in the water). to reduce this effect a vessel would be lowered further into the water by ballisting more and create a positve suction head. Pump impellers if continully run with a large negative head will cause a lot of erosive wear.

Hope this is of any interest to you guys

There was some suction of air from the RPBD hose connected to the Ball Valve Dave which I taped up.

Even with the Ball Valve in place ... once the hose is raised up to water level the vacuum is lost from the RPBD preventing my raising the Sequence off the ground Twisted Evil

I have had to connect it whilst the pump is running Rolling Eyes and being the DIY DID I am Embarassed It`s very annoying.

Mio I can sypathise with you. I had the same problems with an old type pond vacume pump which was fitted with a similar type pump.

Have you thought about using a Aquamax eco12000 or larger and placing this in the water. I have done this with a overthe wall skimmer, which had similar problems with priming. However when fitted actually on the skimmer itself, under the water it works a treat.UnfortunatlyAquamax pumps are expensive and there is also the possibility of the koi damaging themselves on anything in the water, but can be protected by incasing in rubber foam. Just an idea Dave

Pump Noise !

Post by Admin on Fri Aug 26, 2011 7:25 pm

I determined to rid the system of internal `noise`and `injury` risk Dave with the exception of Air when choosing an external pump this time....

What prompted my decision was how loud the much smaller pump was in the QT... twas deafeningly so with my ear pressed against the outside Shocked
