Electrical parameters (only for reference,parameters can be customized for specific requirements)

Model No.VoltageMax load currentMax static liftMax flow ratePower consumption






  •  Information including continuous working time, working temperature and medium is required to be pre-confirmed with professionals; pump cannot work with high temperature or corrosive fluids.

  •  When pump is connected into circulation system, load current will be reduced to 70~85% of Max working current (opening outlet current).

  •  The head means the Max vertical lifting height of water,the flow is 0L/MIN@max head.

  •  The max flow rate means flow rate with no lifting height(according to the curve bellow)

Characteristics of three-phase water pump

1.DC Low voltage safe and reliable

2.Three phase brushless sine wave control technology

3.Eliminate high-frequency electromagnetic noise, smooth and silent

4.The pump body and the drive can be separated and resistant to high temperature

5.Magnetic isolation design, leakage proof, waterproof grade IP68.

6.Acid, alkali and salt corrosion resistance, oil resistance, organic solvents and other liquid media (consult in advance)

7.Constant power can be customized (for example, 12V 80W water pump, Constant Power 80W with voltage varying between 12v-24v)

8.Constant speed can be customized (keep the speed unchanged when the load changes)

9.Accurate dry run protection and Jam protection based on current detection (programmable protection mechanism)

10.Soft start eliminates the peak voltage and reduces the starting current

11.Suitable for Music fountain and other high-frequency start- stop application

12.MPPT function can be customized for solar power supply to avoid poor startup when the light is weak.

13.The pump and pump control system can be customized for various application environment requirements
