In modern industrial applications, hydraulic systems are the key to providing powerful and precise power. And our hydraulic oil pump motor is the heart that drives this system. We specialize in designing and manufacturing a range of high-performance hydraulic oil pump motors, specifically designed to meet the stringent requirements of the global market for reliability, durability, and energy efficiency.




Core advantages:
Excellent energy efficiency performance: Our motors comply with international energy efficiency standards (IE2, optional IE3), significantly reducing power consumption during operation and helping you save significant long-term operating costs.
Strong starting torque: specially designed for high starting loads of hydraulic pumps, ensuring that the motor can start smoothly and reliably even under full load or overload conditions, avoiding system startup failures.
Durable and sturdy, maintenance free: Made of high-quality cast iron casing, with protection level of IP55 or above, effectively preventing dust and moisture. Enhanced bearings and F-class insulation system ensure that the motor can operate continuously and stably for 7×24 hours even in harsh industrial environments.
Low noise and low vibration: Precise dynamic balancing technology and optimized cooling fan design minimize operating noise and vibration, creating a more comfortable and safe working environment for you.
Global applicability: The standard voltage is 380V/50Hz, and 415V/60Hz or other special voltages and frequencies can be customized according to your needs, making it easy to integrate into devices around the world.
Our hydraulic oil pump motor is an ideal driving source for various industrial hydraulic power units (HPUs), widely used in:

High precision concentricity
The motor axis and flange stop are processed with high precision to ensure perfect concentricity between the motor and the oil pump (plunger pump, gear pump, vane pump).
Compact structure, space saving
Without the need for couplings and brackets, the overall structure is more compact.
safe and reliable
Rotating parts are not exposed, making operation safer.
Using high-quality copper wire windings, with low temperature rise and strong overload capacity.
versatile
Can directly replace similar hydraulic power units from imported brands such as Rexroth and Parker.
Can be matched with various hydraulic pumps: CB-B gear pump, CY series plunger pump, etc.
