How to choose DC brushless water pump?

1. First determine the working voltage, current, head and flow, the size of the caliber, the maximum head of the pump's general standard, refers to the static head without water flow when pumping water to the maximum lift, if the customer asks to pump the water to a certain height To maintain a certain amount of water flow, the head required to select the pump must be higher than the specified pumping height. This specific is determined by the supplier based on actual conditions. Refer to the head flow graph.

2. Determine the volume shape requirements (thread interface, inlet and outlet direction, caliber size, etc.)

3. Determine the working environment (temperature, medium)

4. Determine functional requirements (time control, motion control, pressure control, flow control, speed control, etc.)
