KSWG non-negative-pressure (without suction lift) pipe network
pressure boosting stable current water supply whole set equipment
(hereinafter referred to as the equipment) is the new generation product
developed by our company on the basis of upgrading the original KSGP
frequency conversion constant pressure water supply series product.
According to the regulations in ules of Urban Water Supply it
is forbidden to directly install pump on urban public water supply pipes
to pump water! This is because that the negative pressure produced during
pumping will influence water use of other uses in the surroundings, or
even cause damage of pipes.
Therefore, during engineering design, the water pool or water tank
shall be firstly built. The urban water supply is put into the water pool
first and then is pressurized to the water supply pipe network of users.
In the case 1. Large investment. Cost for the building of water pool
(water tank), cost for installation of new water treatment equipment as
the water source in water pool is easily polluted an d cost of daily and
regular cleaning and sterilization of water pool (water tank)
shall be taken into consideration.
2. Water source is easily polluted. As the water pool (water tank) is
open, impurities, microbes and small animal bodies may easily pollute
the water source, especially in summer, the water is easily deteriorated
and smells off.
3. Waste of energy The pressure of urban p ipe network firstly
changes to zero and then start to pressurize from zero. The original
pressure is wasted and the model of pressure boosting pump is enhanced.
4. Waste of water source Water seepage, water running, water leakage
and evaporation may occur in the water pool. Moreover, regular rinsing
and sterilization costs labor and water.
5. High noise When the water level in the water pool (water tank)
descends due to water use, the large noise of water flow from tap water
and noise caused by operation of old style DL pump may exist.
The above problems can be thoroughly solved after adopting KSWG
non-negative-pressure (without suction lift) pipe network pressure
boosting stable current water supply whole set equipment produced by
our company.

1. When the pressure of tap water is lower than the set pressure
required by user, the control system will automatically control the
frequency converter to start the operation through frequency conversion
soft starting until the actual working pressure of user pipe network is
equal to the set pressure. The frequency converter controls the frequency
conversion pump to operate at a constant rotation speed. The higher the
pressure of tap water is, the lower the rotation speed of frequency
conversion pump is, and vice versa. When the pressure of tap water
equals to the set pressure, the frequency conversion pump will delay the
time and sleep, which makes full use of the original pressure of tap water
to ensure that the pressure required by user is constant. When the pressure
drops to the awakening value, the water pump will be automatically
awakened.

2. The water inlet of frequency conversion pump is connected with
the stainless steel stable current compensator, and the microcomputer is
always inspecting the pressure inside the stable current compensator.
Through the inspection to pressure of inlet water and automatic vacuum
suppresser, it is ensured that there is no negative pressure inside the
stable current compensator so as to guarantee the normal water supply
of tap water pipe network.
3. When tap water stops water supply, the equipment will automatically
stop. When the water supply is available, the equipment will automatically
start. In case of power cut, the normal pressure low area water supply
of tap water will automatically resume.
4. When producing instant negative pressure, please stop all power
frequency pumps first and then delay the time of frequency conversion
speed reduction without stopping the machine, which not only ensures
water use for user but also alleviates the condition of negative pressure.
1. Saving a total investment of 70%.
No need to build water pool or water tank. Directly connected with
the tap water pipe for pressure boosting water supply, which makes full
use of the original pressure of tap water and reduces model of water pump
(original water pump requires 60M lift, and the current one requires
only 30M.)
2. Water quality is pure
The pure tap water is directly supplied to user after pressure boosting
by the equipment. It is connected in sealed condition, which is absolutely
isolated from the air.
3. Saving water of 20%
Hermetic structure prevents the occurrence of running, dripping,
leakage and seepage, and the water wasted for regular cleaning and
sterilization. It is directly connected with tap water pipe.
4. Saving power of 70%
It makes full use of the original pressure of tap water pipe and
compensates the pressure amount that differs. When the tap water satisfies
the requirements, the equipment will stop its operation. The effect of
energy saving is so prominent that it can reach above 70%.
5. Saving space and installation time
No need to build water pool or install water tank with the whole set
equipment leaving the factory. After reaching the site, the water inlet
pipe and the water output pipe of tap water of user is directly connected
with the equipment with simple construction, short construction period
and small landing area.
6. Saving manpower and material resources
The water quality is not polluted through adopting the equipment.
No need to install sterilization equipment. Twice pollution is prevented.
The equipment is provided with small pressure stab ilizing tank, which
can further save the investment. As no water pool or water tank is requir ed,
the use is very economic that it saves the costs for regular cleaning and
sterilization.
7. Low noise
As the water pump is directly connected with tap water through
stable current compensator, there is no large noise of water flow from
tap water. The system adopts stainless steel light vertical multistage
centri fugal pump, which can gre atly reduce the noise caused by operation
of water pump.
8. Advanced control system
The equipment applies fuzzy control and integrated control etc.
world advanced control technology and is provided with powerful
remote supervising function and wireless supervising function (optional).

The model selection for KSWG non-negative-pressure (without
suction lift) pipe network pressure boosting stable current water supply
whole set equipment is based on the water inlet amount of tap water
(specified by tap water pipe diameter pressure and length etc. conditions),
actual w ater con sumption, height of buildings etc. data. The perfor mance
form of model selection provided by our company complies with the
following principles:
1. The flow indicated in the form is designed according to the unit.
The equipment model is of common model. Our company can redesign
according to special requirements of customers.
2. The equipment flow indicated in the form does not include flow
of standby pump. The quantity of water pump in the form includes two
sets for use.
3. The specification of stable current compensator recommended
in the form is evaluated and calculated accord ing to the conditions that
tap water satisfies customer requirements. If the tap water pipe diameter
is very slim or the pressure is very low and the water inlet amount can't
satisfy the demands at peak time of water use, the volume of stable current
compensator shall be recalculated. The recommended formulae are as
follows:
V volume=(Q outlet-Q inlet) t
3 Q inlet water inlet amount of tap water at peak time of water use (m /h)
3 Q outlet water consumption by customer at peak time of water use (m /h)
t continuous period at peak time of water use (h)

set as the percentage of const ant pressure (generally 80% of 4020). For
modificati on of other parameters, please refer to SAMI, GS user manual
for details. It is noted that 0127 is the displayed value of actual pressure
value of pipe network, refer to the value of 0127 for 4020. For example,
when the pressure of pipe network is 0.5Mpa, 4020 can be set as 20%. 3202
is the lower limit of pressure of whole set system plus pump pressure
(generally 80% of 4020). 1401 is set as 8. 3205 is the upper limit of pressure
of whole set system minus pump pressure (generally 98% of 4020). 1402
is set as 9.
