2. Product overview :

QJ series deep well submersible waterpumps are widely used in farm irrigation, sprinkler irrigation, getting water from well, water supply and drainage system for industrial and civil building, water diversion project in hilly and mountain areas water drainage project in at low-lying areas, water supply and drainage in urban and rural's mining enterprisesand various ther kinds of water conservancy facilities. Its features are that the Motor and pump are assembled into a whole, so that it is simple in structure, convenient to assemble and disassemble, easy to use and maintain safe to operate. Otherwise, it covers an small area and does not pollute water.

3 QJ using condition:

(1) 380V voltage deviation is no more than ±5%,frequency is 50HZ, three-phase power deviation is no more than ±1%.

(2) Motor cavity must be filled with water.

(3) The first stage impeller of the pump should be more than 2mm below the moving water surface, pump unit should be less than 70m below the static water level.

(4) The distance from the motor bottom to well bottom must be more than 3m.

(5) Water temperature should be no more than 20°C.

(6) Sand content of the water ( by mass) should be no more than 0.01%.

(7) PH value of water 6.5-8.5.

(8) Hydrogen sulfide content of the water should be no more than 1.5mg/L.

(9). Chloride ion content of the water should be no more than 400mg/L.

(10). Water yield of water source should ensure the requirements of pump continuous working.

Q: my sump pump keeps filling with sewer water. i cant figure out why or where it could be coming from. and the smell is awful.: I'm guessing that instead of the ground water being pumped to outsde somewhere, it was installed into the sewer system. If a check valve wasn't installed or if it leaks by, and your sewer line is backing up, it will backfeed down the outlet pipe and into your pit. If you had a lot of water coming in from the ground, it would force the sewer water out of a drain somewhere, like a laundry drain, sink drain, shower drain, or toilet. If this is the case, get your sewer line to the main checked and have the sump pump installed properly.

Q: how much is it to replace timing belt and water pump on a Chrysler voyager 2002?????: Two engines were available in the 2002 Voyager - a 2.4L 4 cylinder engine and a 3.3L V6 engine. The 4 cylinder was timing belt driven but the V6 uses a timing chain with no set replacement interval. Replacing the timing belt and water pump in the 4 cylinder is going to be $500-$850.

Q: just changed the water pump on my lower unit installed the lower unit and started motor now there is no water coming out of the upper flow tube is it becouse the engine is not warmed up yet or is something not lined up ...........: sorry but warming the engine will not affect the water flow. i had this problem i did not have the impeller installed properly.....took it to service center 3 hrs and $185 all new water pump kit fixed my problem . would have saved me alot of time and trouble if i had taken it in earlier

Q: they say a water pump going bad is supposed to weep out of that hole....Yet I see that a new water pump kit has two gaskettes.some o rings....is it likely that it can leak from these sources and still not come out the weep hole?They talk about berring that could go bad or seals gone bad...does this occure in the area that gets inserted into the engine( the turbine portion of the pump)if you had to guess..where is the most likely area for a water pump to fail...if seems like I have wetness off to the left( back toward the firewall) and less off to the right( front of the car)..more off the left..it is very subtile off the right.I don't see anything coming out of the weep hole..BUT the weephole is directly on top( dead center)and back towards the engine in this model. I have the car jacked up on the passengers side/next to the wheel wellso the fluid is most likely to flow backwards toward the drivers side.: A water pump could have all the works above the water, pulling via suction and pushed via atmospheric rigidity to a optimal of roughly 33 ft. Or it could have the motor above water and the lifting mechanism below with an prolonged rod connecting (like an oil properly with the donkey engine on the outdoors), yet a gaggle of weight and friction. Or it truly is waterproofed and the motor and pump decreased down the drilled shaft on a plastic pipe with an electric cord jointly with and push the water up. The final is a submersable. further sump pumps and recirculating pumps the place the cord, motor, and pump are below the liquid.

Q: What causes a water pump on a car to go bad????? and are they a pain to change by yourself?????: the corrosion is the main cause, corrosion is caused by using water coming by the faucet, that water came with some minerals and stuff and the engine at high temp activate those minerals and react causing that brown water (acid water) so the best way is adding a nice mixture of coolant and destilated water is the best but if you dont have that water at hand use some radiator coolant aditive, it will neutralize the effects of the regular water coming from the faucet making that will not make your water pump last forever but your whole system will last many more years

Q: Hi there: my water pump is leaking, and my coolant lelel keeps droping, same problem. Im not sure if coolant flows through the water pump?: While it may seem the water pump is the most likely culprit, I agree with the thermostat solution. Usually, when a water pump fails, it does so gradually, reducing the flow and showing intermittent overheating-usually under load or high temp conditions first. The thermostat, however will cause an immediate overheating situation. You should just go ahead and change the thing anyway, as it's only about five bucks and MAY take 10 minutes to change. It's probably time anyway! Ron Hatton Gadgetman Technologies

Q: Fire hydrant and fire pump adapter difference: Fire hydrant is out of water, the water pump is water supply to the pipe network

Q: In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?: Use 2 units and reserve 1 units. You can open 2 at the same time. Can three drive at the same time, depending on your water pipe layout, whether there are three sets of pipes, yes, three units open at the same time.

Q: What is the part called on a water pump that does the actual water moving. I want only this part to make my own water pump using a different motor and pulley.This is for lifting water 18' high and circulating through 1/2 to 3/4 inch pipe. Hoping to get about 6 gl per min: The impeller.

Q: OK so i am new to RVing....I have an older 1971 trailer pull forester....It has a your normal fresh water inlet on the outside of the trailer, fresh water tank, and water pump. My question is actual a double part question #1 When i screw the hose on the inlet and start filling the water tank i hear it going in but i still have no water coming out the faucet...Does this have to do with the water pump? why am not getting water to anything except i hear the tank filling up?!?#2 Is the Water pump A/C or D/C......I have that little pull knob (that i guess turns it on or off) and i was curious if i needed to be hooked up to the Battery in front to make this work? or should it work with the regular AC that everything else is working on?Thanks for any help: There should be a switch to turn on your water pump and they are normally 12 Volt.There should also be a separate battery that runs all the 12 Volt systems in your RV.When you turn on your water pump it should build up pressure then shut off.It will turn back on as you use it.I think they are set at 40psi.I think you are going to find that you either have a dead battery or your pump is no good.The battery is usually located in a side compartment.Good luck.
