Application

• General civil engineering and construction work.
• Drainage for rain water and sump
• Manhole and pit drainage

Feature

• Adopting new developed small & high torque motor, and urethan rubber for Impeller so that is strength to lubrication, it performs excellent pump characteristics.
• Aluminum die casted motor frame and adopting rubber materials brings weight and size down.
• Vortex structure relieves Impeller lock from sand, and easy disassemble and assemble.
• Built in auto-cut prevents motor from burn.
