Hydraulic Pumps & Motors
High-Performance Hydraulic Power for Industrial, Mobile & OEM Systems
Hydraulic pumps and motors are the core components of any hydraulic system, responsible for converting mechanical energy into hydraulic energy and back again to power machinery. Hydraulic pumps generate flow and pressure, while hydraulic motors convert that fluid energy into rotary mechanical motion to drive equipment with connections made by pipes and hoses.
These components are essential in industrial, mobile, and OEM applications where reliable power transmission, durability, and efficiency are required.
At Nott Company, we supply a wide range of hydraulic pumps and motors engineered for demanding environments, including agricultural, construction, manufacturing, and material handling systems.
How Hydraulic Pumps & Motors Work
Hydraulic pumps draw fluid from a reservoir and convert mechanical energy into hydraulic energy by creating flow and pressure. That pressurized fluid is then directed through the system to actuators or hydraulic motors, which convert it back into mechanical motion.
This closed-loop energy transfer allows hydraulic systems to deliver high force and precise control in compact, efficient designs.
Types of Hydraulic Pumps
Different pump designs are used depending on system pressure, efficiency requirements, and application:
- Gear pumps – rugged, cost-effective, and widely used for general applications
- Vane pumps – smooth operation and moderate pressure capabilities
- Piston pumps – high efficiency and suitable for high-pressure systems
- Variable displacement pumps – adjustable output for advanced system control
Each pump type is selected based on performance needs, system complexity, and duty cycle requirements.
Types of Hydraulic Motors
Hydraulic motors convert fluid power into rotational force (torque) and are used in drive systems such as conveyors, winches, and mobile equipment.
- Gear motors – simple and durable for general-purpose use
- Gerotor / orbital motors – compact and efficient for low-speed, high-torque applications
- Piston motors – high-performance solutions for heavy-duty systems
- Variable speed motors – optimized for efficiency and control
