Air mixing is unavoidable.
Remarkable water head or pressure Loss
May need secondary pump
Discharging height much less than designed level
Flow speed lower than designed parameter
Full pipe transportation difficult to realize;
Cavitation erosion, waterhammer, pipe burst, internal
deposits are common.
Hard to maintain capacity, or cope with increased volume
demand.


Molecular Viscosity is not the major reason for
energy or pressure loss during liquid piping.
Instead, air bulbs inside the pipe lines or pumping
systems plays leading role in generating resistance
leading to loss of water head (pressure).
Decreasing air mixing and rectify air/liquid flow
routes establish VACUUM FLOW which will boost
and maintain transport speed at high level.

Unique and world largest siphon vacuum system
Vacuum status and rectified flow;
Remove air resistance inside pipes, no air discharge valve
is needed.
Utilize potential energy to the maximum;
Increase speed and volume 20-115%
Maintain pipe Filling degree over 99%
Pipe wall smoothness no major effect on speed;
Avoid pipe crack, cavitation, waterhammer, internal
deposit;
Discharging at higher points (30-150%) and transport
longer (40-180%) with less or no energy consumption.
Increase existing piping capacity shortly with little extra
investment
4m pipe diameter and limitless line length

Over 100 successful projects in 30 years;
Pipe diameter from 300 to 4000 mm;
Transportation distance over 100km;
Ideal for large scale and long distance water
transportation
Overpass 8m rise over original water level
Flow faster than gravity or pressurized systems
Save money, save power, save pipelines, save time for
clients.
Undertake impossible mission.
1. Long Distance Water Transportation






To boost existing pipeline capacity in a short time
with small investment
No power demand for downward pipeline;
Much less power consumption for upward pumping
ɸ4m or bigger pipeline and over 100km distance
Overpass 8m rise over original water level
Flow faster than gravity or pressurized systems
Vacuum flow
No air accumulation

2. Tap Water Distribution
Just need one rectifier at the beginning of pipelines;
to ensure nonstop water supply to wider area end-users
4m down the inlet level without secondary pump.
to boosts 20-80% supply capacity with Automatic
Response to demand change and 10-40% power saving.
Prolonged lifetime of pipelines by avoiding high
pressure, pipe cracking and sludge deposit
No dead corner in the whole supply system
Ideal for fire hose
Upper: conventional
Lower: vacuum flow can
go to higher floors
3. Hydro power application





Reduce air mixing
Reduce resistance and energy loss
Reduce cavitation and water hammer
Maintain full filling degree
Higher generation efficiency
4. Industrial water, AC water circulation
◦ Cooling water is usually circled with pumps. SiphonFlow
can do better with 50-80% of power saving.
5. Deep sea mining
6. Siphoned installation for old and cripple
reservoir to prevent deluge;
7.Automatic irrigation network starting from
the reservoir;
Save power and increase cooling efficiency






Siphoned installation for pumping water during low
water level of the reservoir;
Siphoned installation for river closure work;
Urban waste water pumping station modification;
Automatic back-filling of underground water;
Take and transport water from negative water head
overcoming high obstacles;
Siphon expulsion of reservoir sediments with no
power consumption.
Mine flood or underground water drainage
