产品介绍小标题.png

With the relatively new technologies, SOLAROOM 3" DC screw solar pumps can be the more reliable and efficient alternative than centrifugal pumps. It can pump out fluid at a fix rate more consistently and efficiently.

Centrifugal pumps require a certain level of solar power to start pushing water, therefore, low sunlight hours such as early morning or evening may not provide sufficient power to run the centrifugal pump. However, Solaroom screw pumps require lower solar power to operate, which allows the pump to start earlier in the morning and continue to operate longer into sunset. In short, screw pumps would run for longer hours per day as they require lower solar power to operate compared to centrifugal pumps.
