Introduction: submersible pump (or electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps.



Submersible pumps are found in many applications. Single stage pumps are used for drainage, sewage pumping, general industrial pumping and slurry pumping. They are also popular with aquarium filters. Multiple stage submersible pumps are typically lowered down a borehole and used for water abstraction, water wells and in oil wells.

Special attention to the type of ESP is required when using certain types of liquids. ESP's commonly used on board naval vessels cannot be used to dewater contaminated flooded spaces. These use a 440 volt A/C motor that operates a small centrifugal pump. It can also be used out of the water, taking suction with a 2-1/2 inch non-collapsible hose. The pumped liquid is circulated around the motor for cooling purposes. There is a possibility that the gasoline will leak into the pump causing a fire or destroying the pump, so hot water and flammable liquids should be avoided.

Q:I think our water pump over heated, will it go back to normal after it cools down? It wasnt turning off?!?! ?
I assume you have a water well pump. The experience I have had, is it will come back on once the thermal safety switch cools down. However, I think you still have work here to do because each time this happens, you are shortening the life of your pump. First you need to determine why it ran hot to begin with. Could be lots of reasons, but just to name a few. -Is your water tank in good shape, with the correct air pressure? -Is the tank waterlogged, too old or leaking? -Any leaks in the service in or to the house? -Is your contact switch working properly, clean contacts, good wire, good connections, breaker etc.? -Is there water running somewhere your not aware of? -Last but not least, the check valve and foot valve leading to the well could also be defective. Just my opinion, I hope this helps to get you thinking. Good luck; flip;
Q:Thermostat or water pump problem?
first check the coolant level, make sure it is full, this may be all it is, it could also be the thermostat went bad, this is not that unusual for a new thermo. to fail, make sure the belt to the pump is good, unlikely the pump is bad if it is not leaking or making any noise at all! but, when the new thermo. was installed did you purge all the air from the system, at times and in some autos air will become trapped and you have to bleed the air out of it, some have a bleeder screw and some don't, the ones that do not have a bleeder then you have to raise the front end of the car to the point where the radiator top is higher than the engine and make sure the heat is turned on and set to high!
Q:What is the relationship between pump power, lift and flow?
N= QH/1000 gamma ETA gamma, severe liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / sec.
Q:water pump impeller replacement in 1979 35hp Johnson seahorse?
i am no expert on outboards. i did put an impeller on one with the same problem. no water output. seems there was a tube, that ran from the pump to the cylinder head. it was cracked, and the water couldnt reach the cylinder head. seems that the impeller shaft should always turn in the right direction, or it wouldnt cool in reverse, if you got this far , i am sure you will figure it out. you must be a pretty good mechanic to get that far,,
Q:To Get At The Timing Belt On a Toyota 3.4L V6, Does The Water Pump Need To Be Removed?
does the water pump first need to be removed? no. but is exposed during the procedure. ----- If so, is there a way to tell how worn a water pump with 85,000 miles is? Like a loose bearing feel, etc? you can check for pulley noise, pulley wobble and coolant condition as a precursor to it's failure, but even if it passes that inspection, it may fail in 1000 miles (example). that's the nature of consumable components. ------ since it costs 300-400 in labor to do those individually, it behooves one to put them both on the same maint schedule. replace both at same time. needed or not. every 90,000 miles. and this is a non interference type engine. no engine damage will occur as a result of belt failure alone. FYI, since it's not an interference engine, if this be an autotrans, you could go longer between belt changes as autotrans have smoother torque apps. purdy much constant torque. my V6 has over 200,000 miles on the belt. water pump too. and i have pristine coolant and no pulley noise. and i'm pushing my luck. i run the risk of a towing bill.
Q:Could an undiagnosed leaking water pump cause the early demise of my radiator?
completely unrelated and it is customary to replace water pump with timing belt BECAUSE the labor require to replace the pump is the exact same as replacing the belt. If the pump was to fail shortly after replacing the belt, you would have to pay for the same labor charge again and a leaking water pump will contaminate a timing belt requiring the belt to also be replaced. Your radiator developed a leak, that has nothing to do with your water pump
Q:Bad alternator or bad water pump pulley?
not a good idea, find the bad part first, could be < idler pulley, tension, power steering pulley, air conditioner compressor pulley ( if it has air ) , alternator besides that, there ain't any CHEAP belts that i know of
Q:Can anyone tell me how to run an electric water pump from a solar panel?
Q:What all do I need to replace the timing belt and water pump?
You should be able to buy a timing belt kit. The kit usually includes a timing belt, tensioner, idler, balancer shaft belt(if applicable). Some even include the cam and crank seals. Water pump is usually sold separate. You should also get a head cover gasket and the spark plug tube seals since you have to pull the valve cover. Last thing would be drive belts since they come off as well to do the job depending on their condition. 1 gallon of coolant. As far as tools you'll need a 10mm,12mm,14mm,17mm and a 19mm wrench and sockets, wratchet, extensions, screw drivers etc... If your doing the job yourself the hardest part will be removing the crank bolt. A powerfull impact gun is needed or a special crank bolt removal tool used for Honda's. A manual to line up the belt and a floor jack and jack stand.One last thing if you do the job yourself, Be sure the marks are aligned properly because if not BAD THINGS will happen$$$$ Good luck and hope this helps.
Q:2002 Mitsubishi eclipse water pump?
There are always two reasons for which mechanic or the car owners should insist to change the water pump whenever, is time to change the timing belt -If your water pump is driven by the same timing belt; you should have to replace it ; or else you may pay more money for real serious damage in the future if it seizes due to high mileage on it or any fatigue of it,s own. -But if the water pump is driven with a separate belt . You should put that consideration in account for the reason to save money at this point, and furthermore prevent any Sudan over heating condition at any given time. The best way to know if your water pump whether driven by the timing or not ! You simply need to find out what type and size engine you have . Then you go to any auto part and ask them to show you the new pump. Try to show them some sign that you are going to buy the pump in order for them to show you the right pump. If that pump comes with a sprocket pulley. definitely is driven by the timing belt. If in fact your water pump is driven by the timing belt- Yes! you should anticipate to prepare a large amount of money to take care of that big damage within that engine( If that engine is interference engine )
