Features
No maintenance required, small size, high efficiency, low power consumption, strong anti-interference ability, and smooth operation.
No carbon brush, no pollution, electronic commutation, long life.
Shock-absorbing silica gel absorbs vibration and reduces noise. The position of the silica gel is adjustable for easy installation.
The stator and circuit board of the motor are potted with epoxy resin and completely isolated from the rotor, which solves the leakage problem caused by long-term diving of the motor-type DC water pump and is completely waterproof.
It solves a series of problems such as the water pump getting stuck and suddenly not starting in complex environments.
The water pump can be equipped with water shortage protection, idling protection, blocked rotor protection, stuck protection and other functions.
The water pump shaft uses high-performance ceramics to reduce costs. The optional stainless steel shaft has high precision and good wear resistance, due to the precise fit of the high-precision sleeve and ceramic shaft.
The water pump parameters can be adjusted according to requirements. The water pump can adjust the head to meters or meters, the volume remains unchanged, and it can operate at a wide range of voltages.
It solves the mortality problem of water pump drivers. The mortality rate of water pumps currently on the market is about ~. After a long period of scientific research, the mortality rate of water pumps has been reduced to less than 5 per 10,000.
The three-phase Hall sensor-free program-driven DC water pump in the water pump series can realize speed regulation, analog signal ~ speed regulation, and potentiometer manual speed regulation, and the flow rate and head can be changed at will.
The three-phase DC water pump in the water pump has soft start, no impact, low starting power consumption, and can be directly connected to the solar panel. The circuit board is completely separated from the pump body. There are no electronic components in the pump body. The pump body is made of high temperature resistant Materials, the water pump can be used in low water temperatures for a long time. It has impeller rotor stuck protection, reverse connection protection, overload protection and overcurrent protection.
If you need to increase the lift of the water pump, you can also connect the water pumps in series, and the lift can be doubled.
When used for amphibious external use, the installation position is lower than the liquid level.
The water pump and its related control system can be customized and designed according to user requirements.

Selection precautions

When selecting, be sure to give the usage environment such as continuous working time, water temperature, medium, etc. Water pump power exceeding a certain power is not suitable for long-term use or For continuous operation at water temperatures above 10 degrees, be sure to communicate with the technician in order to choose the most suitable water pump!
The above current is the opening current of the water pump, which is the current when the water pump is placed directly into the water without being connected to any system. It is also the maximum current of the water pump. When the water pump is connected to the system, the working current of the water pump will be reduced to the maximum load current.
The lift of the water pump is the maximum water delivery height, that is, the flow rate reaching the maximum lift point is zero.
The flow rate of the water pump is horizontal flow, that is, the flow rate of horizontal pumping water.

The difference between two-phase DC water pumps and three-phase DC water pumps without sensor intelligence
Two-phase
series

Sensor drive, the circuit board must be built-in, it cannot Speed regulation through intelligent methods
Three-phase
Series

Three-phase DC is completely different from three-phase AC. Three-phase DC refers to sensorless drive, and its power supply method is the same as that of single-phase. Like a two-phase water pump, there are only two wires, positive and negative.
Intelligent program driver, no sensor, the circuit board can be externally installed, and the pump body can withstand high temperatures.
Adjustable speed~analog signal potentiometer speed adjustment [optional]
Locked rotor and reverse connection protection, overvoltage and overcurrent protection, overtemperature protection
Soft start, low starting current, no Impact, especially suitable for direct power supply from solar panels

Instructions for use
When used for diving, put the water outlet pipe on the water outlet and lead it out. When diving, connect the water inlet pipe to the water inlet.
The colored wire is connected to +, the blue wire is connected.
Check whether the voltage of the power supply is consistent with the requirements.
Reliably secure the water pump.
Running without media is strictly prohibited.
Things that should be paid attention to when using the water pump
Try to reduce the time when the water pump is idling without water.
When the water pump is working, it should be immersed below the water surface.
Ferromagnetic impurity particles are not allowed to enter the friction of each bearing of the magnetic rotor. After transporting the medium that is easy to crystallize or precipitate, it must be flushed in time. The operation is to pour clean water into the pump after stopping the pump, and discharge it after operation. Solid particles on the conveyor belt When using medium, it should be filtered at the inlet of the pump flow pipe.
The water pump should operate at the specified temperature. It is strictly forbidden for the medium temperature to exceed the standard, which may easily lead to magnet demagnetization and control circuit performance degradation.
Before connecting the hose to the pump outlet, remember to drain the air out of the pump.
Never reverse the polarity of the circuit! ! ! Also, does the DC power supply powering the water pump exceed the maximum rated voltage of the water pump, otherwise the pump will be burned out? Note that the DC power supply must be connected here!
The operating environment of the water pump is clean water medium.
◆The control box of the water pump is completely waterproof, but it cannot be placed in a high temperature environment. Under normal temperature working conditions, both the water pump and the control box can be put into the water. The water pump can withstand high temperatures, but please note that the water pump can be completely put into the water under high temperature conditions
How to choose a pump that suits you
◆ Understand what level of lift and flow you expect to achieve with the working voltage and current provided in your application environment. It should be noted here that the maximum static head refers to the maximum height that the pump can pump without flow. Therefore, when choosing a pump, you must choose a pump with a maximum head higher than your needs
◆Understand what you need The size of the pump, including the water inlet and outlet, is too large or too small, which is not easy to use in actual use
◆Working temperature, medium, such as if you choose a pump that cannot transmit acidic liquids To transfer acidic liquid, you are buying a useless pump
◆There are other requirements such as time control, pressure control, whether speed adjustment is required, etc.
