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:What's the difference between a double suction pump and a single suction pump?
From the literal sense to understand, double suction pump is the impeller at both ends of the water inlet, and the single suction pump is from the impeller at one end of the water.Dual suction is mainly used in the process of large flow and low lift. When the pump flow is greater than or equal to 280m3/h, the caliber of 200mm or more, if the use of a single suction pump, then the speed requirements of about 1450rpm in order to achieve the suction requirements. However, if the double suction pump is used, the size and weight of the pump are reduced, and the speed can be increased, the volumetric efficiency is increased, and the reliability of the equipment is improved.Single suction pump, also known as end suction pump, single suction pump flow is relatively small. The same flow, single suction of small size, but the axial force, bearing a large burden. The cost of single suction pump is low, the price is reasonable, widely used, but in many ways it is not as good as double suction pump. If the inlet pressure is higher, the general choice of double suction wheel can be solved. Because the axial force balance of the impeller of the single suction pump is a big problem.
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
First, the wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious. Can also be described according to what you pump model, the pump is divided into piston pumps, screw pumps, impeller pumps and centrifugal pumps.Secondly, under the standard condition, the higher the efficiency of the centrifugal pump, the higher the speed determines the size of the centrifugal force, the higher the speed, the greater the centrifugal force, and vice versa. Plunger pump and screw pump is not the same, the speed of speed and efficiency basically no impact. Third, in addition to buying the pump, you can let the manufacturer give you an FM curve, so you can see the frequency of mediation when the water pump efficiency changes
Q:I'm trying to convince my dad to get a 1984 Porsche 944 for $900. However, the car need a new water pump and I was wondering how much it would be to get the part installed at a shop. What would be a good estimate as I'm planning on going to more than one place. So included with the price of the part and installation is this a good deal? And is the car reliable?

Q:I just opened up the water pump on my '86 cr250 and found it to be pretty dry. Found out why as soon as I threw some light on it. Yep, all but a TINY hole in both hose nipples (?) are completely gunked up in some nice light green/white crap.Does anybody know what this is? Okay obviously it's coolant, but why is it so dry? What causes it? My bike never quot;overheatedquot;, but there's very little travel room for the liquid. What should I do now? Clean it out and run new water through it?
Appears your cooling system has not been flushed for years thus the build-up of slime, (seems maybe even 'dry-slime'). The cooling system should be flushed clean, a new water pump and gaskets installed.
Q:We recently fixed our stone water fountain, and now we're trying to get it working. THe pump we had was about 5 yrs old, and didn't work. We've tried to get a new one online, but it only had one inlet for the water to go into the pump, and that got clogged in a matter of about 5 minutes. Since our garden has many trees, it's almost impossible for us to keep the fountain 100% clean all the time to prevent clogging. Anybody know where to get a pump for a 15gal fountain, that has multiple inlets?
fountains are us
Q:i mean, the water that runs through the ground from rain and ends up in the pit in the basement,is it clean to drink in an emergency? live close to a public road where they salt for snow and ice, so do you suppose that is in the water?
yes, I would bet it is in the water. sump pump water is consider by the industry to be GRAY water. you don't want to drink it. if its an emergency, you could boil it, but not in w.v. if you are living there with this type of spill they incurred. even boiling that water will not work. better safe than sorry
Q:Can I use Ultra Blue gasket maker on a water pump? The packaging is not labeled high heat.
i could replace the gasket now particularly of attempting to recollect on end leak. reckoning on the place you reside, it somewhat is gonna get chilly authentic quickly. Wrenching in chilly climate sucks. And if the unique water pump has by no skill been replaced, you're able to think of approximately doing that while you have it aside, no count if it is not too costly for a clean/rebuilt pump. i be responsive to it could be in simple terms my success to take all of it aside, replace the gaskets, then have the water pump crap out 2 months later. DOH!
Q:Im half way through replacing my water pump and im stuck...the power steering pump pully blocks access to the final bolt that needs to be removed so the water pump can be removed so i can replace the water pump... any hints on how to get to the bolt so i dont disassemble something i dont need to?

Q:What are some good brands of aquarium water pumps? I have had bad experiances with Hydor Seltz (cheapest ones I could find, ugg, I know, you get what you pay for) pumps, failing very quickly, and sounding like plastic gears grinding around inside. What is the best kind to get?I need one that's around 150gph
PowerHead? or Sump Pump? I have used hagen aquaclear powerheads on my saltwater tanks for years 24/7 without a problem. I just purchased 3 MaxiJet 1200 powerheads and a wave timer to see haw they do, 6 months now 24/7 and so far so good. The longest lasting Sump Pump that I have ever owned is made by Ehime, I've had it for 14 years now and it's still going in one of my tanks. I better cross my fingers on that one.LOL
Q:could you explain the process by which water is pumped out of the ground for purposed such as drinking water or irrigation? Can you put it in terms a high school senior would understand?
(1) Identify your potential water source through various methods. (2) Drill a small exploratory hole to different depths, test water pressure and water quality. (3) Drill the complete borehole for production and retrieval of the groundwater. (4) Complete the physical well, will a sheath to allow in the water at the wanted levels, solid pluge to keep other levels out. (5) Insert a chemical and physical filter system (small screen membranes, activate charcoal and diatomaceous earth, etc.) (6) Put in the submersible pump and plug it in. (7) The pump is made up of a motor, an intake and a centrifugal pump. It's all sealed so no water can penetrate through. The water is suctioned into the centrifugal pump, which is an impeller type device. The water is then pushed out at a much higher pressure rate than it came in. This is how the pump works from the bottom instead of above ground. The water is sent to the pressure tank, sometimes referred to as a holding tank, and is kept at a constant pressure, so when you turn on your faucet or shower, the water comes out quickly. As you use the water, more water is pumped into the tank and as the pressure drops in the tank, it will automatically come on and pressurize again.
