Highland Rice harvester LPV50+LMF50 Hydraulic Motor Pump System information:

Hydraulic transmission system have been around for decades, for one main reason: they don't require an external energy source - the force of fluid provides them with the energy they need. Pump is the variable displacement hydraulic pump that is with charge pump, the control way of variable displacement pump can be manual or hydraulic operated, and can simply control speed, direction and power of the output shaft.

Hydraulic motor pump system user shall ensure that the hydraulic pump uses the correct formulation of the medium to ensure the cleanliness of the operating medium of the equipment, and shall not contain solid particles.
