Pre-Rostral Manhole System
Excellent non-blocking performance and high efficiency! No worries about overload, and continuous operation in the atmosphere is possible.
A powerful vortex is generated by the combination of the vortex that occurs in the same direction as the rotation of the impeller at the pump's suction inlet and a specially designed pre-swirl chamber. This product is a manhole system that utilizes this pre-swirl flow. It features excellent clog-free performance and high efficiency. The power characteristics are limit load characteristics. Therefore, there is no concern about overload. It can operate continuously in the air and is suitable for the pre-swirl chamber. 【Features】 ■ Excellent clog-free performance and high-efficiency screw-type submersible sewage pump ■ Power characteristics are limit load characteristics, eliminating concerns about overload ■ Suitable for pre-swirl chambers due to its ability to operate continuously in the air ■ Equipped with motor protection devices, thermal protectors, and water intrusion detectors ■ Clog-free vortex pumps are also available in the lineup to meet diverse needs *For more details, please refer to the PDF document or feel free to contact us.
