Product overview

Traditional water supply method cannever live without water storage tank. The water of the water storage tank isusually provided by the tap water pipeline network. Thus, after the water withpressure enters the water tank, the pressure will become null, this makes alarge quantity of energy wasted. Having been developed by the professionaltechnicians of our company based on variable frequency constant pressure watersupply equipment, TWG non-negative pressure water supply equipment is thecomplete set of water supply equipment that can be directly connected to tapwater pipeline network and generates no negative pressure to the tap waterpipeline network and brings about no secondary pollution. He can fully utilizethe pressure of tap water pipeline network to supply water with directsuperposed pressure, thus, it avoids secondary waste of energy and secondarypollution, greatly cuts down the investment on the equipments and shortens theconstruction period. TWG intelligent non-negative pressure superposed watersupply equipment is composed of variable frequency control cabinet,non-negative steady flow tank, vacuum suppressor, liquid level detector, bump,complete pipeline valve unit, steady pressure tank, instruments for equipmentsand the like. It can be applied to all water supply places that requireimprovement of water pressure, constant water pressure and flow. It is a newgeneration energy-saving product in the field of water supply.

SWG non-negative pressure steady flowsuperposed water supply equipment adopts the advanced non-negative water supplytechnology. It is highly suitable for unstable urban pipeline water supply orthe water consumption points located at the end of the urban network thatrequires pressurized water supply system. Via advanced non-negative technology,safety and environmental protection in water supply is assured, and it isguaranteed that it will never exert negative pressure to urban network.

Applications: high-rise building watersupply,second pressurized water, hot water boilers, pressure -steady of pipeline;

Performance advantages: can replacehigh water tank and water tower, the pressure is quite stable to avoid of pumpstarting and stoping frequently, starting sensitively and reliably, low noise;

Technical Parameters: Flow 0-1000m3/hr;water pressure 0-2.5Mpa; equipment volume:0.11-8.64m3;Control:frequency,orother customer specified;

Performance advantages

1, No need of pool, energy andresources saving

SWG non-negative pressure steady flowsuperposed water supply equipment with advantage of economic, health,remarkable energy-saving effect, it’s proved that it can save more than 50% ofthe construction costs of the pool, compared with other water supply equipment,can save 20% to 40% by using SWG non-negative pressure steady-flow superposedwater supply equipment

2, Easy to install, saving footprint

SWG non-negative pressure steady flowsuperposed water supply equipment  can beequipped with horizontal steady-flow tank or vertical steady-flow tank. 2 tankshave different characteristics: horizontal tank occupies small space: vertical tankoccupies small area. The manufacturing and testing of steady-flow tank are accordancewith GB150 "steel pressure vessel", but without compressed gas insidetank, so to be excluded in the scope of the pressure vessel lines. The insidewall of tank using the anti-corrosion advanced "841 epoxy polyamide wallpainting of food container ", products meet national food hygienestandards.

3, Wildly application and high adaptability. 

SWG non-negative pressure steady flowsuperposed water supply equipment can be used for domestic water supply, butalso for the fire-fighting system, you can configure any type of pump, it shouldbe equipped with a fire pump.

when the device is used for fire-fighting.

4, Full-featured, high degree ofintelligence

SWG non-negative pressure steady flowsuperposed water supply equipment  usesadvanced frequency control technology, with protection function of soft start,overload, short circuit, overvoltage, under voltage, phase, thermal. The thesignal alarm, self-test, fault diagnosis automatically in exceptionalcircumstances, and also automatically adjust water flow based on the level ofwater.

5,Advanced and reliable quality

The accessories of SWG non-negativepressure steady flow superposed water supply equipment after screening manymanufacturers with reliable quality assurance,the product key parts, such as:motor, water pump bearings, inverters, circuit breakers, contactors , relays,etc. using the international and domestic high-quality brand-name products.

6, Personalized design, unique

SWG non-negative pressure steady flowsuperposed water supply equipment according to the pressure situation of waterpipe network , to be equipped with small pressure tank, avoid of pump starting frequentlyto extend equipment life, its storage, regulator performance is moresignificant.
