Why choose us

About Us

FAQ:

1. HOW TO CHOOSE OUR BRUSHLESS DC PUMP?

You must seriously look into some of the following parameters or to provide us with these parameters, when you choose a brushless DC pump:

1) Pump model: Firstly, to choose the right and suitable model.

2) Power supply of the brushless DC pump:

A. Transformer switch power supply: Switch to the correct voltage and current the pump supplied.

B. Battery power supply; how much Battery capacity Amp / hour?

C. Solar power supply; Select the correct open circuit voltage and short-circuit current.

3) Working voltage: 4.5VDC-24VDC (Any voltage from the voltage range)

4) Power: 0.65—120W

5) Static water head and static flow rate:

Static water head: It measures at zero flow rate that the water goes up to its max height.

Static flow rate: It measures when the pump outlet does not connect any pipe, then the water flow comes out in a certain time. For example: To choose a pump that has 3 L/min flow rate at 2 meters height, then, the static water head of the pump must be higher than 3 meters that we can get a 3L/min flow rate at 2 meters water head height. (For more details, please refer to the flow rate VS water head curve, or ask our sales department).

6) Application environment:

Ambient temperature    Humidity    Ventilation     Use device submersible or non-submersible, etc.

7) Medium: water, engine (edible) oil, anti-freezing liquid and other fluid temperature; PH value.

8) Choice of pump performance: How to choose a good quality and reliable brushless DC pump

a. Outward appearance: Elegant design and nice look, exquisite production  

b. Electrical performance: Low vibration, low noise, low start current, high efficiency, low rising temperature.

c. Structure: very simple and convenient installation, low and convenient maintenance.

d. Regular and professional manufacturer and dealer.

2. HOW TO INSTALL OUR BRUSHLESS DC PUMP?

1). The best installation way of a brushless DC pump is in horizontal direction, the outlet is upward, (If you require another installation method, please inform us when you purchasing, to enable us to adjust all the specifications of the pump to a best working condition.).

2). To installs an anti-vibration cotton pad to the bottom of the pump.

3). The pump inlet and outlet should be connected to a silica gel hose, if a hard objects instead, anti-resonance should be attendant.

4). To install a brushless DC pump in a water pipe: If a hard tube connected to the inlet and outlet of the pump, the inlet and outlet will be marked with a standard thread, when you choose our pumps.

5). No beating and throwing the pump, when installing.

6). Please install and use the pump according to its working conditions (You’re better tell us your appliance working condition, fluid working temperature, power supply, working voltage, etc. When test the pumps, please pay attention to the power polarity, Power reverse polarity is strictly prohibited.).

7). When choose an installation place, please keep away from the strong magnetic objects.

3. HOW TO USE OUR BRUSHLESS DC PUMP?

1). Turn on the regulated power supply, transform the power to a fixed voltage which supplied by the pump,such as 12VDC or 24VDC the pump supplied.

2). Put the pump out of the box and find out the power cord positive and negative electrodes; the red line is for the positive polarity, the black line is for the negative polarity( if the wires are other colors, it also will be marked the positive and negative poles, please check the test report attached with the goods.).

3). Put one-third of the pump body in to water. Please do not put the whole body into water if the pump is not submersible, in case the pump burns off. However, the inlet and outlet of the pump should be in water.

4). To connects the positive pole of the power line to the cathode of the pump, the negative pole to the anode of the pump, so that the pump can start and operate normally.

5).  Please try to put the pump into clean water to avoid blocking by solid, dirty substances, etc.

6). Please operate the pump within the specifications that we offered, please see the test report.

7). Please do not move, bit, or toss the pump heavily, in case of affecting the performance of the pump.

8). It is easy to use the pump if you read the test report, manual or specification sheet carefully in advance. Should you have any question or problem, please feel free to contact us.

4.  How to slove the problem of pump do not run and no any sound, when apply the power to the pump?

    You need to check the electric circuit and Wiring.

5.  Pump do not run and make buzzing sound, when apply the power to the pump:

You need to check if the power is too small. (Power supply≥1.5 times as much as the pump power)Meanwhile, check the pump rotor to see if there is dirt blocked the pump.

6.  Pump does not spray water:

       There might be many causes:

       You’d better check if there is air or any other solid matter coming into the water pipe which is connected to the inlet of the pump, to ensure there should no air or any other solid matter in the pipe and the pump should have enough liquid inside.

   In this matter, if the pump still cannot work, you need to open the pump to check inside of the pump to see if the shaft was broken, the gasket was broken or misplaced, the rotor was displaced, etc.

  If the rotor was displaced and is difficult to move, to check the shaft and shaft sleeve, if they combined too tight, the rotor will generate heat during operation, thus, the temperature will increase, and on the other hand, the power transmitted by the magnet will be decline as a curve with the increased temperature.

  Usually, Within the working limited temperature of the magnet, its ability of power transmission is reversible, in the opposite, it is irreversible, because when the magnet cooled down, it lost its ability of power transmission, and cannot restored anymore.

   If it is not handled promptly, the increasing temperature will fade the magnetism of the magnet away. The filtering and high temperature media should be considered to ensure the working temperature of the rotor cannot over its limits.

  When considering of the speed, you’d better check the pump speed itself to see if it is normal, and the pump body temperature is high or not, the pump has water or air inside or not, you need to ensure there is no water and air inside the pump, stop and restart the pump at least 3 times and let the pump work several minutes to make sure it operates normally.

7. Pump cannot achieve required water head and flow rate when works:

     You need to check if there is air or water inside of the pump chamber; if there is, remove them, re-start and stop the pump at least 3 times.

8. There is abnormal sound when the pump operates:

       You need to check if there is dirt and solid particles, remove them and clean the inside pump chamber.

9. Motor gets heating when operates:

        You need to check if the rotor is blocked by other particles, to check if the power supply is normal, to check if the pump housing is broken and water penetrates into the pump housing.

10. There is large vibration and loud noise, when pump operates:

         Put the pump on a smooth board or desk, connect to the power supply and turn to a rated working voltage, if the pump sounds noisily with large vibration, hold the pump in your hand: if you feel the vibration but no noise, the causes may be that the rotor deviated, the shaft hole enlarged or the impeller damaged or deformed. Solutions: change new materials; if you feel slight vibration and low noise install Anti vibration soft sponge/pad; if you feel loud noise and large vibration, replace the rotor and cover.

11. Pump has loud noise while operating:

        You need to check all the components inside the pump, such as the rotor, shaft, impeller, gasket, O-rings, front cover and the pump housing, etc. Check the power supply and if there is dirt and solid objects inside the pump housing.

12. Pump gets Leaking:

        The pump housing might were not well assembly or the seal ring was not installed.
