Voith fluid couplings the solution for all start-up and clutching problemsVoith fluid couplings of the series TD, TDM-SAE and TDVFM-SAE are start-up and damping couplings for easy installation to diesel engines. The series TPD-SAE and TPKD-SAE additionally offers a clutching function.

The transmission of torque in the Voith fluid couplings occurs contactfree by the flow of the operating fluid in the circuit usually standard hydraulic oil. The main components of the fluid coupling pump wheel (impeller) and turbine wheel (runner) do not touch.

The connecting dimensions of the SAE types comply with SAE standards. Apart from traditional diesel engines, super charged diesel engines and gas engines can be started up loadfree, and heavy masses can be accelerated without problems.

Customer benefitsThe fluid coupling in drives with diesel or gas engines provides multiple benefits. With just one component, it always offers you a choice of the following functions: damping starting overload protection clutching.
