MI250 by Poclain Hydraulics : the new high-displacement hydraulic motor for the first time in Europe

Poclain Hydraulics is turning towards its more demanding markets with a new hydraulic motor that has a maximum displacement of 30l. This product will satisfy its customers’ requirements for reliability and lifespan, while also coming in a reduced size.

Performance :

The MI250 offers an efficiency rating of over 90%. Its 30l displacement used at a maximum pressure of 350 bar (5076 PSI) enables it to deploy a torque going up to 140 kNm (187 HP) for a power of 500 kW (671 HP). Its reduced dimensions accentuate the available power density.

Reliability :

The technology of the MI250 is that which Poclain Hydraulics has been using for 50 years in its radial piston motors. This proven design allows for great reliability and a lifespan adapted to the most demanding applications such as grinders, industrial machines, marine winches, drills, etc

Integration :

To address the strict constraints on machine manufacturers, Poclain Hydraulics has designed the MI250 with reduced dimensions and weight, thus facilitating its integration. For easy torque arm positioning, it is available with several shaft interfaces (shrink discs or male splines) and has a support surface with 4 DN32 ports.
