NFWG series non negative pressure frequency convention water supply equipment is a new type frequency convention equipment. There are two types. One is cabinet model equipment, the other is tank model equipment. The equipment can be connected to the municipal water supply network where the pressure is not high enough. Use sensor to detect the outlet pressure and compare with the setting value to calculate the pressure needed to be boosted, pump quantity, motor rotation. The equipment can make full use of the original pressure of the municipal water supply network. It will not cause negative pressure of the municipal water supply network. It uses the stainless steel non negative pressure tank to replace the old pool to avoid second pollution. It is the new general energy saving product in the water supply industry.
Main application
1. Residential water supply: High building, residential area, villa, etc.
2. Public places: Hospital, university, gymnasium, golf course, airport, etc.
3. Commercial building: Hotel, office building, department store, large-scale sauna center.
4. Irrigation: Park, playing round, garden, farm, etc.
5. Manufacturing industry: Manufacturing, lavation equipment, food industry, factory, etc.
6. Other: Rebuild of water pool or other form.
Features
1. Non-negative pressure
The system can connect to the municipal water supply system to boost it and will not cause negative pressure for the municipal water supply system.
2. High quality, PC controls:
Invented by us, have multi-function, can supply high standard precise control. It arrives to the advance level in the world.
3. Boosting
When the equipment is running, it can use the pressure that water supply network supplies and boost base on this, Compared to suck water from the normal water pool, it can use less pump or lower the rotation to save energy.
4. Not stop water supply when power is off
When the power supply is out off power, system can supply water with 747D and. Bypass, etc, that is, system can supply water with the municipal water supply pressure.
5. Clean
The flow parts are all stainless steel which is the material of food grade, it is conform to the international water related rules. The cabinet type non-negative device can ensure the water in the cabinet to be circulated by the usage of residents. The closed type non-negative device can circulate real-timely to ensure the safety of the water.
6. Energy saving
The system needs not the water pool etc. To store the water, which save the space. The system works high efficiently, which can save 60% energy. There is pressure of the municipal water network. When running, the system only need to boost on the pressure of municipal water network. The system need not to be monitored by people, and need not the water pool, etc. And there is no water quality handling machine. It is not needed to be cleaned and disinfected timely. So energy saving is obvious
- Q:mercury 9.8hp.installed a new water pump impeller and still no water circulating through engine. no blockage anywhere. now what??? i`m stumped at this point.
- I have seen this many times on 9.87.5Merc'sThere is a plastic o-ring under the power head and it is probablly melted closed.There is a way to fix it without removing the powerhead.Remove the lower unit and pull out the water pickup tube.Then use a piece of brake line 5/16th sharpen on a 45 degree angle and push up the opening for the water pickup to open the passage.This will fix your water problem.
- Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?
- What should have Water Leakage place, check all the toilet faucet is Water Leakage, Water Leakage, water heater and so on, if no problem, to check the pump, which has a check valve, when the valve is broken, can not maintain the pressure, there will be the phenomenon
- Q:I want to replace a water pump for my friend. I can't find any books on this car. I'm not sure how to replace this pump. Looking at new water pumps there lookes like 10 bolts, but on my chevy truck there was only 4. I don't know if all holes take a bolt or not, or if I need to take something out before I take the water pump out.Anyone ever changed a water pump on this car? or know what book or website I can look at which will give me an idea.
- autozones web site has some good instructions on most popular cars
- Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
- Mainly determined by the function of the water supply pump and the circulation pump.Replenishment pump is mainly to supplement the loss of the system, so the general flow is smaller, larger head, single pump water model in a small flow situation, many are not up to the required head, can only use multi-stage pumps.Circulating pumps are generally large flow, low lift, heavy efficiency, economic operation, and hydraulic model point of view, are single-stage pumps more appropriate, especially single stage double suction pump.
- Q:Im an SHO fan looking to get another one. The car I'm looking at is a 1991 Taurus SHO. Price is pretty cheap and nothing wrong with it except he said the water pump will need replaced soon. Ive looked at water pumps and Im aware of cost. Im decently savvy with car repair but there are a few things ive never learned. How easy is it to replace a water pump? Should I have a go at it myself or is it better to be done professionally? What is the general cost for a garage to switch out the water pump?

- Q:water pump has small leak
- Realistcally you have a 10 12 months previous motor vehicle, so your water pump has used up its existence sorry. provide up leak products are in lots of situations an outstanding powdered aluminum/epoxy combination and NO they gained't fix a water pump seal. previous provide up leak products have been easily extra suitable yet used asbestos as a leak fix, so the government banned its use. My advice, is to save around slightly for yet another value, because it does sound incredibly steep. Sorry approximately your concern. Please remember anti freeze can bypass on the instant, so do no longer threat an engine overheat at a foul time, carry 2 gallons of spare coolant
- Q:We had a thunderstorm followed by power outage last night, this morning I went to use the water and it slowly went dead.I began by inspecting the pressure tank and pressure control switch, then found the outside water pump breaker was tripped, upon resetting the water was back on!But wait, after about 1-2 minutes of use there was a small quot;POPand smoke from the control switch and the breaker tripped again. It seems now that every time the water pump kicks in I've got a 50/50 shot of the circuit breaker blowing. I'm not sure what to do now, I don't want to keep resetting my pump breaker, we really didn't get that much rain so I don't know what would be causing this issue?Any help would be greatly appreciated.Thanks!
- So, you say you have a 50/50 chance of the water pump's breaker popping out when you use it now. I would assume you mean when you've used it enough to make the pump come back on. Actually, I think I'd start by replacing the pressure switch, regardless of which system you have, submersible or above ground, the pressure switch will be where it can be serviced. I really can't think of any reason why a pressure switch would cause a breaker to trip, but at least that way you'd know you've done all you can do. If your system is a submersible you'll have to have a water company come out with a boom truck to pull that pump up out of the ground.
- Q:honda acord water pump 1988

- Q:Hi, I need to create a portable shower and was going to go the DIY route, i wanted to use water pumps normally used in ponds, aquariums etc etc as the means of creating water pressure for the shower, the shower need not be really strong in pressure but it should be strong enough such that a person can take a bath using it.height of the shower would for sure be less then 6 feet,question , water pumps are rated at gallons per minute or some equivalent rating, how strong a pump or how much GPM should i be looking at ?
- if your sink does not need a pump, you shower won't either....most water systems are pressurized
- Q:My boyfriend told me that my car needs a new water pump. He said this because when you start the car, it sounds like trickling water is coming from somewhere in the engine bay. The car overheated once before and he put coolant in it, ever since then, it hasn't overheated. But last week he told me that I shouldn't drive it at all because the pump is about to go. I went out today and started it to see if I can hear the quot;grindingnoise that I read about online and all I hear was the trickling sound. It's rainy outside so I can't tell if the pump is leaking water from the quot;weepquot;. Is it the water pump? I want to make a two mile round trip to go pick up sushi and the place is a mile there and a mile back. Will I seize my engine or get stranded if I make this tiny trip? Is it my water pump?
- Year Engine? (Water Pump effecting the Shifting_____:] No!) Could Clogged Valve Body or you just need to change the Fluid Filter. Trickling Sound OK, Never Heard that one. {Hard to say----is the Fan directly connected to the Water Pump?} With the engine off does the Fan move if you Push Pull it up down? Yes Bad Pump Bearing. Do you see a Coolant leak under the center of the engine behind the Radiator? (Leak from weep hole).
