Our passion for high performance in hydraulic drives us
Founded by Roberto Casappa more than 60 years ago, this multinational company is still totally owned by the Casappa family, in its third generation.
We design and build the main components of hydraulic system with passion and care in detail.

The compact design allows to be mounted directly on engine motors. The new "MVPD" series allow higher flow rates than traditional pumps with the same dimension, higher machine speeds without affecting the design of the hydraulic system and a high power-to-dimension ratio.

Displacements from 0.85 in3/rev (14 cm3/rev)  to  5.17 in3/rev (84.7 cm3/rev).
Max. peak pressure up to 5075 psi  (350 bar).
Max. speed up to 3500 min-1
  • Exceptional working life expectancy.
  • Low noise emission.
  • Drive shaft bearing suitable for radial and axial loads.
  • Multiple combinations.
  • Short response time.
MVPD additional features
  • Higher speed.
  • Higher power -to-weight ratio.
  • Cost-optimized design. 
Controls
  • Min. and max. displacement limiter.
  • Pressure compensator.
  • Flow and pressure compensator (Load-Sensing).
