Products Overview of Non-negative Pressure Water Supply System
1. no negative pressure (no suction) automatic water supply equipment directly use the municipal pipeline network as water source, forming a continuous airtight relay pressurization water supply patterns, completely avoid lowering the water quality caused by the traditional secondary pressurization water supply system, completely ensure the water quality of the municipal water.
2. make full use of municipal water pressure itselfe, make up the pressure difference, effectively and maximize the frequency conversion effect.
3. traditional secondary pressurized water supply way, the water is tapped into reservoir, which leads to original pressure wasted and reduces the neighboring user pressure, while this equipment directly fill pressure to original water pressure, so as to realize the optimal limited pressurization, guarantee the adjacent pipe pressure was not affected.
Performance Characteristics of Non-negative Pressure Water Supply System
1, directly connected with the municipal pipeline, no reservior needed.
2, small volume, occupies little space, convenient installation.
3, water tank, pumps are made of stainless steel, no secondary pollution.
5, the water pressure is steady, won't cause adjacent user pipe pressure fluctuations.
6, automatic operation, can unattended.
7, protection function is well-found, the fault automatically alarmed.
8, make full use of the original water pressure, make up pressure difference, high efficiency and energy saving.
When the municipal pipeline is high-pressure, equipment in stop condition, municipal water goes directly to the user network through the by-pass pipe.
When the municipal pipeline is low pressure, equipment automatic starts the pump on the basis of original municipal water pressure, carries on the variable frequency speed regulation pressurization water supply.

- Q: My timing belt is worn but has not broken yet. The mechanic first told me it would be about $200-250 to replace the belt. Then he called back and said it was going to be $550 because on an Aveo you have to replace the water pump at the same time. I asked if it was possible to do just the belt and he said quot;well the water pump will probably break when we take it outquot;. Is this a sign that I should just break down and go to a dealership so that my water pump won't quot;breakupon removal?
- He is saying that, because the water pump is driven by the timing belt and you SHOULD replace it while you are in there. Why pay twice down the road? Sure the belt can be done without doing the pump, the fact that he said the pump will break when doing a belt is complete bullsh*t though. There is no need to do anything to the pump when changing the belt other than taking the belt off the pulley. That's it. Generally, I just add maybe .5 hrs to the labor for the belt when doing the pump also, DOUBLE doesn't make any sense whatsoever. Unless he is worried about pump BOLTS snapping from CORROSION (that may be it) when removing the actual water pump, that is the only thing that can possibly justify doubling the labor, they may be in water jackets in the block. He should, however, make you aware that that is a possibility and not automatically assume that will happen and charge you for it. Depends, if they are careful with the removal, it should just add another 20-30 minutes to the timing belt job. Either way if you turn down the pump and they are telling you it will still break(?), go somewhere else. I work on cars everyday and would never charge someone an additional 300 dollars off the bat assuming the bolts will break. There are tricks to prevent that as well (penetrating fluid/PB Blaster). Generally if that does happen, one maybe two bolts would break tops and that still doesn't justify the additional labor... Hope that helps....
- Q: The water pump in my trecel is damaged and i need to take it to a shop that's about 20 minutes away from my house will turning on the heater and adding coolant help me to get the car there without damaging the engine
- Yes. I would recommend taking a jug of water with you. Keep an eye on your temp and if it gets too hot pull over wait a while then add more water. Turning the heater on will help pull the heat away from the engine which will help keep the engine cool. I just had the same issue with my 95 Civic and the shop was about 25 minutes from my house.
- Q: it just go? I was told that my water pump had leaked at least for awhile before it went and if it had been in the garage someone competent should have noticed it. Then other people have told me No it just goes.whats accurate?
- You can have a small leak for a long time before a complete failure. Some cars, it's harder to inspect the front of the block than others. It's possible that even a good mechanic wouldn't have noticed it if all he's doing is a quick oil change. You might have noticed it yourself: a water pump leak would leave you with a sweet smell after you park. You might even notice it while driving, if the fumes get pulled into the car.
- Q: for the water pump in MY car that he has been using for his job!! He has threatned that the water pump cost $400 - 500 dollars but I didn't hear abut that when it was done!!! We are breaking up and it is My car but he says that he is taking te water pump out! Can he do that??? We also ave a daughte but I will ask about that later!! TRUST ME!!! I need to know about Custody Battles in Anoka or Hennipin County, Monnesota, 55433!!!! Please Help!!!!!!!!
- I don't know so much about legal issues, but 4-500 dollars for a water pump sounds about right. The pump costs about 80 but you have to take out the engine to get it. Usually when they replace the water pump they'll replace the timing belt, too, which again adds to the cost. If he takes the pump out, it means the engine will be out, too. Engines are really heavy, so I doubt that he could do it on his own. If he has a mechanic do it, the car will be stuck at the mechanic's until you get a replacement part, and he still has to pay $300 in labor just to get the thing out of there. It is pretty much, then, an idle threat. He could however, do quite a lot of damage to your car with a hammer. However, that would be vandalism and he would go to jail for it. If he has already paid for the repair, he can't really sue you. He can, but the judge should look at it as a gift, which he can't get back.
- Q: Is it a must to change the entire water pump since only driplets of anti-freeze leak out over a 7day period from the bottom of the pump? Can i simply change the gasket and make it all better? Water pump is pumping and making no noise, vehicle isnt over heating.
- your water weep hole is on bottom of water pump also.if its the water pump weep hole leaking.that signs of water pump shaft bearing is going bad.water pump needs replacing.
- Q: I am trying to replace a water pump on my ranger and i have all the bolts out. It seems to be stuck i think it is because of the oring around the outside of the pump andy ideas of how to free it?
- First of all, make sure you have removed all the bolts. They can be found in the most unlikely places Once you are positive all the bolts are out gently tap on the pump around the perimeter to break it loose. I have changed many water pumps and seldom do they just fall off. Do not hit the belt pulley as you will need to reuse it. I use a ball peen hammer. You don't care if you damage the pump but why ruin a good hammer. If that doesn't work then you need a mechanic. Most probably to find the bolt you missed. .
- Q: toyota prius 2002 inverter water pump where is located and how to replace and buy

- Q: In the past 9 months, Ive went through 6 or 7 gallons of antifreeze, I was told this was not normal. Ive had my coolant tank flushed 4 times this year, only to be told thats not normal and one lasts a few years. Now that its colder outside my car takes a while to run hot of course, but during the summer it ran hot in about 15 minutes tops. I got a brand new coolant tank before I got another flush because I did have a leak, but that did not combat the problem. I had my radiator looked at and I was told thats fine. So im thinking either a cracked head gasket or a bad water pump...help please. im getting tired of putting money into this car only for the same stuff to keep happening.
- if it is a head gasket your oil will have water in it, my guess is a water pump or hoses, check the oil first to see if there is water, then have the water pump checked, then hoses, process of elimination works the best 99% of the time
- Q: my 98 expedition keeps over heating, i replaced the water pump, thermostat,coolant. it will be fine one minute then it overheats. weather im on the road or sitting at a light. i also replaced the fan clutch. thanks!
- I would check the radiator first and if its not it then your looking at a bad head or head gasket if u have already replaced what u said u have
- Q: The dry season river dock company from the wharf area maximum height difference of 17 meters, is the need to purchase pumps for wharf surface wash pump water, the pipeline outlet pressure to the ordinary fire water pump pressure standard, the best do not directly into the water, can be placed in the dock or wharf surface from 10 meters (below three terminal position floor, 6 meters on average one floor), to facilitate the maintenance of. What type of water pump is the best choice? What brand is the best choice at home and abroad?! Be deeply grateful！
- 0.1MPa 1, according to the water pressure of the hydrant, dry season difference 17m geometric head for 17m, the pipeline resistance calculated according to 10%~20% 1.7~3.4m, from 3m, so the pump head should be 17+3+10=30m, considering that this is the dry season conditions, when the water level elevation is lower than 17m when the actual demand of low lift in 30m, it is not recommended to 35m head to head design, 30m under various conditions are enough (the actual operation of pump lift by lift device, so if the head is too high may lead to the actual use of pump bias conditions, and low lift and large flow operation, the flow of super power) selection of I don't know your personal needs, can not make a judgment, suggestion the flow rate and pipe diameter according to the economic flow rate of 2.5m/l is about to take it.2, from the operation of the pump, it is best to water intrusion, is higher than the pump center line, so it is best to get the pump installed under the negative on the second floor, if you can not meet the high water pump and the center line, there are three choices in the selection of a pump: 1, submersible pump (by landlord excluded); 2: the ordinary centrifugal pump + water diversion device (water diversion valve then available irrigation water or vacuum diversion device, this approach might not be used, and irrigation valve trouble, valve is broken with it, such a small pump vacuum water cost is too high); 3: self suction pump. Recommendations may consider self suction pump, self-priming pump is also divided into no sealed automatic control self-priming pump and general cantilever self-priming pump both, but the installation height is still lower, the better, because the lower the water level of the entrance, the more likely to suck water.
