2. Product Overview
3. Model
AQUA series high-pressure self-priming pump is a compact water supply system suitable for home water
intake, well water lifting, pipeline pressurization, garden watering, vegetable greenhouse watering and
aquaculture. It is also suitable for water supply and drainage in rivers, wells, rural areas, hotels, canteens
and high-rise buildings. The power supply frequency is 50Hz, the single-phase voltage is 160-260v, and
the three-phase voltage is 380v; see the product nameplate.
Note: The s ingle-phase high-pressure self-priming pump is divided into automatic pump and
non-automatic pump. All non-automatic pumps can be converted to automatic pumps. The automatic
pump is made up of a non-automatic pump that is added an automatic device which consists of a
pressure switch and a pressure tank. The function features: when the power is on and the faucet is
opened, the pump will work automatically, and vice versa. If it is used with a water tower, through the
connection with an upper limit switch, it can automatically work or stop based on the water level in the
water tower.

5. Warnings
Please follow the Specification strictly when using the product.
Before connecting to power, please check the insulation resistance carefully to
prevent electric leakage.
The pump should be grounded reliably and equipped with a leakage protection
switch.
Do not touch the product after it is powered on. Do not wash, swim or put live
stock in water in the vicinity to avoid electric shock.
The pump must be first powered o ffbefore repairs in case of any malfunction.
1. The power must be turned o ffbefore installation and maintenance. The
pump should be grounded reliably. To prevent electric shock, be sure to install
a leakage protection switch. If there is moisture on the plug, it will cause electric
shock. Please be careful.

2. Do not use any liquid other than water. When using readily soluble substances
like benzoic acid, flammable materials like gasoline and viscous bottleneck liquids,
it is easy to cause a fire.
4. Avoid operation in a waterless state, for it will shorten the service life of the
pump. When the motor is overheated, it is easy to have malfunctions. Do not
expose the pump to direct light during operation, for it will affect the service life
of the pump. The automatic pumps will enter the water shortage protection
system to protect the pump, so when the user uses the pump for a second time,
he only needs to re-plug the plugto use normally (the tap will open automatically).
3. During operation, it is strictly prohibited to touch the pump. Do not wash,
swim or put livestock in water in the vicinity of the work area in case of accidents.
If abnormalities are found during operation, such as abnormal noise, less water
outlet and intermittent water flow, the power should be cut o ffimmediately
to check and eliminate the fault. When the pump is wet, do not touch the pump
when it is powered on in case of accidents. Avoid splashing water on the pump
and prevent thepump from immersing in water.
5. Before starting, first move the fan blade to check whether the pump can
operate flexibly; then unscrew the water injection plug, fill the pump with clean
water from the water injection hole, then tighten the water injection plug after
the air is exhausted.
Keep the valve almost closed at startup; when there is water discharged, adjust
the valve to have the required flow.
8-1. When the ambient temperature is lower than 4¥, please take antifreeze
measures to prevent the pump from frost crack;
8-2. Keep ventilation
7. If the pump is installed indoors, a drainage system must be arranged near
the pump.
Prevent the pump from immersing in water, for it may cause the motor to burn
out or electric shock. If the pump is not installed as required,which results in the
user抯 property and safety loss, the company will not bear the responsibility.
9. If you have any questions, please refer to the Specification or contact us.
6-1. During installation and maintenance, ensure that the pump won抰 be
accidentally powered on. If it is not used for a long time, close the pipe valves
at the water inlet and outlet, and pay attention to cut o ffthe power first.
6-2. The pumped liquid may be hot and under high pressure. Before moving
and disassembling the pump, the valves must be closed before draining the
pump and the pipe to avoid burns.
6-3. Supply power according to the voltage indicated on the nameplate. If the
pump is not used for a long time, it should be stored in a dry, ventilated and
cool place at room temperature.

B: Precautions for water inlet installation:
The inlet diameter should be at least thesame as the
outlet diameter, so that its pressure drop, high flow
and noise can be minimized.
A: Precautions for installation of water inlet pipe
1. When installing the pump, it is forbidden to use soft rubber hose in the water inlet pipe to avoid deviated
suction;
2. Install the bottom valve vertically and 30cm away from the bottom, so as not to absorb the sediment.
3. Each joint of the inlet pipe must be sealed; try to reduce the number of elbows, or it won抰 be able to
absorb water.
4. The diameter of the inlet pipe should be at least similar to the diameter of the water inlet to prevent
excessive water loss and affecting the performance of water discharge.
5. During operation, pay attention to the water level drop, the bottom valve should not be exposed to the
water surface.
6. The length of the water inlet pipe is greater than 10m, or when the inlet pipe lifting height is greater
than 4m, the inlet pipe diameter shall be greater than the diameter of
the water inlet.
7. When installing the pipeline, ensure that the pump will not be subjected to the pipeline.
8. In case of special circumstances, the pump series are allowed to not install the bottom valve, however,
in order to prevent particles from entering the pump, the inlet pipe must be installed a filter.

Electrical connection and protection shall comply with the local regulations.
The operating voltage is marked on the nameplate, please ensure that the motor matches the power
supply. If the pump operation area is far away from the power supply, the power cord should be properly
thickened, otherwise, the great voltage drop will affect the normal operation of the pump. If the pump is
used outdoors, the extension cord must use a special rubber cable dedicated for outdoor use.
Check the motor rotation (three-phase motor)
Check if the pump is running normally and the rotation is correct. It can be seen from the
vane end: rotating clockwise indicates that the pump is running normally. If the rotation is not correct, cut
o ffthe power and swap the two power supply leads.
1. When the automatic pump is in use, if it keeps running when the faucet is closed, turn down the
breaking voltage of the pressure switch, that is, to rotate the variable nut counterclockwise to obtain a
lower switching-on pressure (if it is a circular switch, turn the screw in the ??direction).
2. If the pump starts frequently (starts and stops) when the faucet is closed, check whether the pipeline
and the bottom valve are leaking, which should be eliminated in time.
3. If the pressure switch is turned on and o ff(starts frequently) when the faucet is opened, the user must
increase the breaking voltage of the pressure switch. that is, to rotate the variable nut clockwise to obtain
a higher switching-on pressure (if it is a circular switch, turn the screw in the ??direction).
Do not wire the junction box unless the power is off.
The pump should be grounded reliably to prevent leakage and be equipped with a leakage
protection switch.
7. Electrical Connection

8
Do not start the pump until the pump chamber is filled with water.
Do not touch the pump unless the pump has been powered o fffor at least 5 minutes.
Do not remove the pump body unless the water in the pump chamber is fully drained!
8. Start-up & Maintenance
Before starting, move the fan blade to check whether the pump can rotate
flexibly; then unscrew the water injection plug and fill the pump with clean water.
When the air is exhausted, tighten the water injection plug. When starting, the
valve should be closed. When the pump is running normally, adjust the valve to
have the required flow (the flow and head range shownon the nameplate).
Notice:
1. If there is no water discharged when the pump has been started for 5 minutes,
turn o ffthe pump, refill the pump with water, or check the inlet pipe for leaks;
2. If there is any danger of frosting or freezing, please open the drain screw plug
to drain the water in the pump chamber. However, when the pump needs to be
started again, the water injection plug must be opened to fill the pump with
water before starting, and then be tightened before operation;
3. If the pump is not used for a long time, the water in the pump should be
drained and the pump body, impeller and bracket must be cleaned, applied anti-
rust oil, and put in a ventilated and dry place for standby;
4. When restarting the pump after a long downtime, please follow the above
diagram;
5. When it is summer or the ambient temperature is high, pay attention to
ventilation. Prevent dew from the electrical parts, for it will cause electrical failure.
6. If the motor is found to be burning hot or abnormal, cut o ffthe power
immediately and check the fault according to the following table.
