SAPSONS Flexible Shaft Machine is a stationary motor-driven rotary tool system designed for precision work. Often used for tube cleaning in boilers, air heaters, evaporators, heat exchangers, and other industrial vessels where internal build-up needs removal. The flexible shaft drives brushes or cutting tools inside tubes that are hard to access. The motor is mounted separately (bench or stand type), and power is transmitted through a flexible, rotating inner shaft enclosed in a protective outer casing. This design allows the operator to work comfortably with a lightweight handpiece while the heavier motor remains fixed.
How It Works:
• A stationary motor drives the flexible cable (shaft).
• The rotating shaft transmits power to the handpiece or cleaning tool inside a tube.
• Flexibility allows the tool to navigate bends and long lengths without damaging the tube interior.
Key Features:
• Industrial Design: Rugged, easy-to-operate machine suitable for heavy duty and continuous work.
• Portable Unit: Self-contained portable unit with carrying handle for easier handling on site.
• Motor: Typically fitted with a TEFC (Totally Enclosed Fan Cooled) three-phase AC motor designed for robust service.
• Horsepower Options: Commonly available in 3 HP, 5 HP, and 7.5 HP motor configurations.
• Speed: Standard free speeds around 1440 RPM or 2880 RPM, depending on model.
• Controls & Protection: Push-button starter includes single-phase protection, overload, and under-voltage protection.
• Cabling: Supplied with long (~20 ft) power cable.
Type
• Heavy-Duty Industrial Type – Higher HP for continuous industrial use.
