Type T (T-12)

Traction-type fluid couplings, with optional brake drum.

Description

Constant-fill soft start for fixed-speed drives.

Fluidomat Type T-12 is a constant-fill, fixed-speed traction coupling — a radially displaceable design with a resilient driving plate on the input side and a metallic-disc flexible coupling on the output side. It gives a smooth, cushioned start while limiting the torque the driven machine ever sees.

Starting torque is adjustable in the range of 180–275%, with normal operating slip of just 2 to 5% depending on coupling size and the chosen starting-torque value. The unit is suitable for two consecutive starts from hot and three from cold, and a fusible plug protects against overload — blowing off at 130°C as standard, with a 160°C option.

Product specifications

Built for dependable, repeatable starts

The T-12 combines a resilient input drive with a metallic-disc flexible output coupling, accommodating radial displacement while protecting both motor and machine.

  • Radially displaceable construction — resilient driving plate on the input side, metallic-disc flexible coupling on the output side
  • Starting torque adjustable in the range of 180–275% to suit the driven load
  • Normal operating slip of only 2 to 5%, depending on coupling size and starting-torque value
  • Suitable for two consecutive starts from hot and three from cold
  • Fusible plug blow-off temperature of 130°C as standard; 160°C available as an option
  • Optional brake drum, mounted on the metallic-disc flexible coupling, for braking-duty applications
