BMV orbital motors are solid and compact design units. They are characterized by low speed and significant torque. The BMV motors are interchangeable with OMV, EPMV and MV motors. The BMV design is based on the internal gear motor design with rollers and disc distribution.

Rotational speed range: from 5 through 510 rpm; maximum continuous pressure: up to 200 bar.

Orbital hydraulic motors of BMV series are bigger size motors of quite compact design. They adopt geroler gear set design with disc flow distribution at high pressure. Gearwheel sets with rollers are suitable for longer work at higher pressures, for operation with thin oil, and for frequent reverse loads. The output shaft adopts tapered roller bearings that permit high axial and radial forces. BMV hydraulic motors series consists of eight models of displacements 314,9 – 969,1 cm3, and powers to 40 kW.

BMV hydraulic motors are available with four shaft versions: cylindrical, splined and 2 involute splined and two square flange with 4 orifices.


  • Displacement: 314.9 – 969.1 cm3/rev;
  • Rotational speed range: 5 – 510 rpm;
  • Maximum pressure: from 160/180 through 200/240 bar (continuous/peak);
  • Maximum power: 35 – 40 kW.


  • Low start-up pressure;
  • Reinforced shaft seal;
  • Disc distribution system with automatic compensation for high efficiency;
  • Tapered roller bearings permit high axial and radial loads.


The MSI motors are used in winches, heavy agricultural and industrial machines, drilling machines etc.
