Product Description:

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:Help replacing water pump?
You can loosen alternator, or power steering pump, or jump belt off of idler pulley if it has one. But I doubt that it is a serpentine belt, just a v-belt.
Q:How to replace a water pump on a 1996 mercury 200 hp?
good answers. forward gear is a good idea, just make sure the controller is in fwd. also. when you turn the driveshaft to put the housing over the impeller make sure to always turn it clockwise from the top.
Q:How do I know if it's my well water pump, thermostat or water heater?
Well, if you dn't have any water, it's not the water heater or the thermostat, it's got to be the pump. Has the circuit breaker tripped? You should check that before you call a plumber.
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:The car water pump is broken. What are the symptoms?
Car water pump damage, water temperature will rise sharply
Q:problem with calpump pw1200 water pump?
CLR soak. Remove the calcium and lime from the tap water use. I would use a 50/50 solution in the inlet and give it 30 min then plug it back in with the in and out in a bucket with the 50/50 mix until it runs like new.
Q:If you replace your water pump, once installed, can you ruin your engine if installed wrong?
Dont know how it is possible to put a water pump on wrong...only goes on one way. if its not right it will leak to all hell. the only way this will hurt your engine is if it ran too hot. Did it overheat before you bought it in to get fixed? now, i dont know what kind of vehicle. some car's timing belts run off of the pump, and even then worse case, with an interference engine, you could bend some valves and your car wouldn't even run which would cost you to fix the head. where did they tell you the clicking sound was comming from? what year/make/model? could be plain bad luck.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The pump suction and pressure side roads shall be equipped with a vacuum meter and a pressure gauge to monitor the operation of the system. When the pump is running, if the suction side of the vacuum decreases, indicating that the performance of water pump or water absorption pipe leakage; if the vacuum increases, it may be blocked suction pipe. The pressure on the water side is too large. It may be less water or the water pipe is blocked. If the pressure drops, the water consumption may increase or the water pump performance will decrease.The pressure gauges on the water side also play an important role in observing the pressure changes at the start of the pump to determine when to open the outlet valve. Usually larger pump starts, should first close the outlet valve to reduce the starting current, until the pressure of the pump rising and stable, then open the outlet valve.
Q:how do i remove water pump on chrysler 3 liter v6?
oh boy i think u have to take the timing belt , matterof factchange the timming belt too , it should be cheaper since it's already open,check pepboys autozone,murray's , they would give u a diagram for it
Q:water pump went bad. changed it. car is still overheating. why?
sounds like a air block in the cooling system. leave the radiator cap off and start it. the air will push the antifreeze out but once the air is out it will start to circulate. you will have to add more antifreeze before putting the cap back on. don,t forget to add some to the reservoir.
