1, Delta water pump adopts independent patented structure, with low energy consumption and high efficiency. It has the characteristics of vacuum water absorption, super self-absorption ability, and can automatically and forcefully discharge the air in the water pipe. Le Tong pump consumes high energy.
2. In winter, it is not affected by climate and water temperature, with low sound and weak acid and alkali corrosion resistance, so it is widely used, while Le Tong water pump is greatly affected by water temperature in winter.
