Priced individually
No rating
12 months of warranty
MACKMA BM250 is the only mandrelless pipe bender that allows for right and left bending. Its innovative design allows you to bend pipes with a diameter of up to 273 mm for a wall thickness of 18.26 mm and a maximum radius in the pipe axis of 1,700 mm.
MACKMA BM250 is the only mandrelless pipe bender that allows for right and left bending. Its innovative design allows you to bend pipes with a diameter of up to 273 mm for a wall thickness of 18.26 mm and a maximum radius in the pipe axis of 1,700 mm.
Manual pipe clamping controlled by a knob with a counter - to guarantee the highest possible level of repeatability. Easy-to-use control panel built into the body. Allows you to save up to 999 programs.
A potentiometer cooperating with the inverter regulates the bending speed depending on the pipe diameter and wall thickness. The design of the machine allows you to create complex bends that require the pipe to pass under the work plate. The modular structure of the bending die pin makes it possible to use tools from other companies.
The bending machine is powered only by an electric motor - without hydraulic elements. This results in low noise levels and operating costs.
To ensure long-term reliability, 100% of the components used in production are of Italian origin. The standard 2-year warranty is proof of the high quality of the machines.
