Archive for the Submersible Water Pump category.

I have a cover over my pool outside, and during the off-season it often gets a large amount of rain water that accumulates in the middle of the cover several inches or more deep. Can anyone recommend a really good, small, reasonable electric submersible pump I can buy that I can plug in outside and toss the pump down in the "pond" of water & pump it off fairly quickly? I am sure nowdays some companies make some nice little portable pumps that are waterproof & submersible.
Thanks for any recommendations you can give me !!
Thx TC & Oil Field, good suggestions - Human-guy, no can do what you say, to start with its round/oval, not square - there are no "sides" - also the pool is 15 x 30, I don’t know if you realize how large that is but there is no way you can pull that huge of a cover tight enough so there is no ponding of water on top, u obviously have no experience w/ this situation.
I wish I could remember the one I used in Arizona for exactly that purpose …..I think it was “little giant”….but I can’t remember …been a few years.
I had a retractable cover and would throw the pump in the middle {it had a garden hose attached to it} and pump it out…….. here is a site you can check.
Little giant is also readily available at Ace I think …Home Depot

i want 2 know all basic info on Submersible Water Pumps like working, principles, construction, etc.
theory of operation:
There’s an impeller attached to the motor shaft, inside a housing with two ports, one for intake and the other for discharge. the spinning impeller puts centrifugal force on the liquid trapped between its vanes, so when it reaches the discharge port, the pressure inside the housing is greater than the pressure in the discharge outlet, forcing the liquid out. Faster spinning means more pressure, greater lift.
Some pumps (for example, those used to supply cooling water to marine engines), generate high pressure by utilizing a flexible impeller on an eccentric shaft (off-center). The intake port is situated at the point on the housing farthest from the shaft, so that the chamber between vanes gets smaller as it spins toward the outlet; when it reaches the discharge, the stressed impeller vanes increase the pressure in the housing.
DISCLAIMER: I just made this up as I went along; I have no formal training in any kind of engineering or design.

hi i have bought a submersible 400w water pump for my rain tank but i need to know if 150 litres per minute output is to much for a rain Tank Pump as i have a old pump on my tank at the moment and it pumps out 53.33 litres per minute
the old pump specs
type - inline
power - 240v
watts - 800w
outlet size - 25mm
volume - 3200 litres per hour or 53.33 litres per minute
new pump specs
type - submersible
power - 240v
watts - 400w
outlet size - 25mm
volume - 9000 litres per hour or 150 litres per minute
its not too much you should look at it like this if its pumping your water theres nothing wrong.

a month. Could someone do the math for me as to what size motor/generator I would need to power the pump?
Your units don’t make sense (that might be the advertiser’s fault, not yours, of course).
Kilowatts are already a unit of power. To drive a 2.16 kW pump you need a 2.16kW motor (or a bit bigger, like 2.5 or 3 kW).
If they are trying to tell you the cost of running the pump on mains electricity, the units should by kilowatt-hours per month. But that’s meaningless number unless you know how many hours a month you are actually going to run the pump
2.16 kW-h a month is only 3 watts, if the pump was running 24 hours a day for 30 days, but 3 watts is far too small to power an outdoor fountain.
It’s best to start at the end and work backwards. First decide what size fountain you want (how high, how many jets, etc), then go to a water-features supplier and find out what size pump you need to drive it.

Its a non submersible pump that I keep underneath my aquarium to pump water from my wet dry filter up into the aquarium. it sounds so loud even when i have the front doors underneath the tank closed. it also gets kind of hot on the metal base of the pump. can i have it covered up somehow or something? how can i also do this safely considering theres a little bit of a heat issue. i dont think its any vibration issue though. the pump is just loud
Some pump are just simply loud. You stated that this is non submersible pump. Is it sitting underwater in the sump? This is a inline pump and should not be really underwater. It was designed to run dry as an inline pump. These pumps are used for close loop in aquariums.
If it is siting on the floor and not in the water, you can prevent it from vibrating is by wrapping it in towel.

the toilet hung up and took the water level down to where the pump couldnt get anymore water. the tank is now full but I have tried cycleing the pump but its not getting any pressure. its a submersible self priming pump, could I still have to prime it?
Make sure the pump is still good. How long did the pump run dry?? One of the things water does as a pump pumps it to lubricate the pump and keep it cool. Make sure the pump is running. If it is running you may not be able to prime it from the discharge if the pump has a foot valve on it to make sure the water does not cycle back through the pump.
Next question is do you have a surge tank? You will have to open a faucet and let the air bleed through the system before you get water again to your fixtures. May take bit.

I can’t afford an electrician right now. I installed a new pressure switch but still no water. I really don’t believe my well is dry either.
Do you have power at the switch? Does the switch pass the power through to the motor leads? If you answer yes to each of these questions, then the problem is in the pump motor or the power leads going to it. Either way, the pump must be serviced. Call the pump service company to send an electrician. Many times, the problem can be fixed easily, other times it must be replaced. Call the qualified professionals to do the work.

toilet start a load of clothes the pump will kick off. You can go to the pump house and move a stem sticking out of were the power hooks up and it will kick back on…please help!!!
the stem you are referring to is on the pump pressure sensor. you need to replace that unit.

I just replaced an old jet pump with a submersible. My question is, how long before the water starts clearing up? It’s closing in on 18 hours, and I know it could take awhile. Is there any clarifying agent that could be added to the well?
Thanks.
Just replacing a worn jet pump and pipe. Submersible is 10+ feet off bottom of 80ft well with 50 ft of water.
Was the well "fract" to increase water, or just a new pump?
Is the pump at the same level? 20-25 feet off the bottom?
If you are bringing up dirty water, it will clear gradually with time. A whole house filter will keep the water from staining your fixtures, laundry and drinking water.
