2. Product overview :

QJ submersible pumps are widely used in agriculture irrigation, sprinkler irrigation, well water lifting and water supply, drain system of industrial and civil building, as well as the hill, mountain areas’ water diversion, drainage of low-lying area, water supply, drainage of industrial and mining enterprises in urban and rural area and all the other water facilities. And the characteristics of them: motors and pumps assembled into one, simple structure, easy installation and removal, small area, simple using and maintenance, safe and reliable operation, no pollution to water, etc.

4.10 Water yield of water source should ensure the requirements of pump continuous working.

Q: Does the water pump pump the coolant into the engine or pump it out?: Strictly speaking, the pump is powered cooling fluid circulation, which is pumped into and out of the water pump is to rely on to complete the engine, the water tank and the pipelines are connected to form a closed loop, the engine cooling water tank, heat release, heat exchange by circulating cooling liquid, and let the power coolant flow up from the water, like the human heart as the power of the arteries and veins are provided by the contraction and relaxation of the heart of the.

Q: I have a submersible pump outdoors for the water to my house. Indoors is a holding tank and pressure gauge. It seems the pressure gauge keeps slowly declining down to 20. Then when the toilet is flushed, the gauge kicks on and climbs to 50. Then left alone for a while the gauge again declines to 20. Do I have a leak somewhere? If so , where? Does the ballast inside the holding tank need to be pressurized? If so, how where? I seem to remember years ago, my husband did something with a bicycle tire air pump. Makes sense? Thanks: I assume you are saying that the pressure drops to 20 when no water is being drawn by any faucets, since that will naturally happen if water is drawn. Four things I would check - first look for leaky toilet float valves - the tank level will drop, and the valve will open periodically to refill the tank if the seal is bad on the float valve. Secondly, make sure you have a check valve installed on the supply line into the pressure tank to prevent water from flowing back down into the well. Third, you may need more air in the tank - I would put enough air in so that the off/on cycle was 60 seconds when one faucet was fully open drawing water. This would not be the cause of leakage, but it could increase the frequency of the 50 to 20 psi cycle. Fourth, I'd adjust the low pressure turn-on point up to over 30 vs. the 20 it is set for now - 20 is probably annoyingly low. Go for a gap of 20 psi from low to high - eg. 30 - 50 psi.

Q: i installed a new pump don't know how to increase water pressure and to what what pressure it should be set: This is very simple i would sugest the pressure to be set betwene 60 to 70 NO MORE THAN 70. 1. turn off power to pump (ether the circut breaker or a switch near the pressure switch) you dont want to weld the wrench to the switch. 2. remove the cover to the pressure switch its self (usly one #2 phillips screw) 3. now you will see 4 wires under some sloted screws nearest to the front of the switch, behint that is 1 or 2 bolts with a spring and a nut. 4. if you see 2 bolts you will want to turn the nut on the larger one to the right. you will want to tighten it about 1 to 2 full turns. (the same goes if there is only one bolt also) 5. now open the valve that is on the tank untill you here the switch click. then close the valve. 6. turn the power back on tio the pump and watch the pressure gauge on the tank. i DO NOT RECOMEND MORE THAN 70PSI. 7. if it goes over the pressure you want repete steps above exept loosen the nut in about 1/4 to 1/2 turns untill you reach the desired pressure 8. if it does not reach your desired pressure then you do the same thing exept tighten the nut in 1/4 to 1/2 turns untill you attain your desired pressure. 9. when the pressure is reached, replace cover so you dont risk rusting the contacts. if you need more help feel free to email me. and i will assist you in any way that i can.

Q: s10 blazer with 130k original miles.. is leaking water but not from the water pump... just replaced it and still leaking from the same area... where are the freeze plugs located? where else could it be leaking from? it lools like its coming from harmonic balancer or close by!!: look at the housing that the water pump bolts to ,it may be busted and there's some of the bolts that go all the way through in to the block if those wasn't coated with sealant it will still leak from the bolts that hold the water pump on,and that will make it appear to be leaking from the front cover,you got two freeze plugs in the front and three down each side,good luck with it,

Q: I have an 8 gpm pump at a depth of 170 ft, I am pumping the water 2000 ft in a 1 1/4 inch line. I need to know how many gallons per minute I am getting.: Use the Bernoulli equation, aka mechanical energy balance.

Q: We use this water pump for about 2 years, and in the last week the circuit breaker trip when we turn on the pump. What should I check first for the problem?: Is it a circuit breaker or a GFCI that is tripping? If a circuit breaker then the pump motor could be frozen or is binding, circuit maybe over loaded because there in now something else plugged into it or the circuit breaker is wearing out. If it is GFCI (and on a pump it probably should be) then you have a ground fault condition in the pump motor or the wiring. In which case I would suggest hire an electrician to sort out the problem.

Q: I have a 1998 ford taurus. It started to over heat so i turned on the heater full blast and it didn't get hot. so i put antifreeze in it and i turned it on and it seemed ok but it started to over heat again and the tank for the antifreeze looked like the cap was going to pop off. I was just down the road from my house so i thought if i drove slow i could make it home and it turned on ok but when i put it in drive it stalled. Does this mean its the water pump??????: Hmm it has somthing to do with all your fluids if antifreeze cap looks like that but it would be best to get it looked at I may be wrong

Q: i have a water leak near the water pump in my 1990 cadillac deville i replaced the water pump but it was remanufactured and a pipe on the back of the water pump can it be a heater core or should i buy a brand new one p.s. water leaks after it passes the radiator: The 1990 cadillac water pumps were big old things. They took up most of the front of the engine and GM left very little room to get to the bolts. One problem you could be having is bolt placement. Not only were there about 15 bolts holding the pump on, but they were also all different lengths. If you do not put them back in the right order you can end up cracking the new water pump housing, or leaving a gap between the pump and the bolt head where water can leak out of. Check that.

Q: How can the pump be stationary?: Rusty, turn with your hands to see the situation, the two bearings filled with lubricating oil.

Q: I know what is the role of the pressurized water pump adapter to the indoor fire pipe through the fire, then the fire truck to the indoor water supply when the water is pressurized by municipal pipelines, natural water, fire water or water itself injection pump adapter? The fire truck is equivalent to a pump from the water extraction and then injected into the water pump adapter? I haven't seen it with my own eyes, so ask, I hope someone will answerIs the fire engine to be used as a pump? For example, in the field of water from fire pool or when municipal water supply network, a head of extraction, the other end of the water pump adapter access outdoor indoor pressure? PS: I'm not referring to the high-pressure water pump adapter, but access.: They answered almost enough, and I would not answer them, and give them to them
