Flexible couplings

Couplings with elastic ring elements  are used to transmit torque at various positions of compressor and pumping equipment. They have high radial flexibility, axial compliance with high torsional rigidity.

The couplings comply with the requirements of API 671 standard.

  Due to the ability to unload the rotor system from reactive forces and compensate for installation and operational deviations and misalignments of the connected rotors, MSK type couplings increase the service life of the supports and the rotor system of the unit as a whole, which helps to increase the equipment’s time between repairs from one year to six years, thereby responding the highest criteria of quality and reliability.

Advantages:

  • long service life, high reliability
  • stability of torque transmission due to the absence of wearing parts
  • compensate for installation and operational misalignment deviations
  • reduce loads on support and support-thrust units by reducing reactive forces
  • have vibration-isolating properties
  • Consistently low imbalance and low power losses
  • increased reliability of elastic element packages due to the use of an anti-fretting protector
  • optimization of weight and size parameters and axial rigidity;
  • do not require lubrication or constant maintenance.
