Mobile machines mainly use I. C.-engines for their drive. With hydrostatic drives hydraulic pumps are directly coupled, with mobile compressors the compressor unit is directly driven. Both units are connected by a flange coupling. It has to comply with a number of specifications – primarily it has to transmit the power reliably so that the pending operations can be performed as requested. 

Torsionally stiff flange couplings BoWex FLE-PA:

Due to their short design these curved-tooth flange couplings are particularly suitable for mounting to I. C.-engines.

Highly flexible flange couplings BoWex-ELASTIC:

Highly flexible flange couplings combine the benefits of the renowned BoWex system with the flexibility of a highly flexible coupling in a compact design.

Highly flexible flange couplings SINULASTIC:

SINULASTIC highly flexible flange couplings cover a wide range of applications primarily for diesel engine drives, but also general drive tasks.

One-piece, flexible flange couplings MONOLASTIC:

The MONOLASTIC flange couplings enable compensating for radial and angular displacements with extremely low restoring forces via the elastomer part. These flange couplings are particularly suitable for the drive of hydraulic pumps in single or multiple arrangement.

Pump mounting flange

For mounting hydraulic pumps to the diesel engine KTR supplies mounting flanges sizes SAE-1 to SAE-6 according to the SAE connection dimensions.
