Feature
●A hydraulic motor is the opposite of a hydraulic pump. The principle of operation is simple - a pressurized working device enters the motor shaft and sets it in motion, creating engine work. This drives e.g. agricultural machines, compressors, etc.
●Hydraulic motors are used in many areas of industry, agriculture, processing and transport.
●The Presko hydraulic motors are characterised by a slow speed and high torque.
●Advantages: absorption, rolling bearing, high starting torque and smooth running immediately after commissioning, easy installation, long service life.
●Our motors can be used as a replacement for BMR, OMR, SMR, SMS, OMZT, OMST, ALSG, OMZS, OMZS, BMS engines.

A hydraulic motor is the opposite of a hydraulic pump. The hydraulic motor produces mechanical work under the pressure of the working fluid. The operating principle is simple: the pressurized working fluid reaches the motor shaft and sets it in motion, which e.g. agricultural machinery, compressors, etc. Hydraulic motors are used in many areas of industry, agriculture, processing and transportation.
