Hydraulic Piston Pump｜High-Pressure Variable Displacement Hydraulic Pump SolutionsHydraulic piston pumps (also known as oil hydraulic piston pumps) are the core components of high-pressure hydraulic systems. Through the reciprocating motion of pistons within the cylinder block, they precisely control fluid flow and direction, delivering stable and highly efficient high-pressure output. They serve as an essential power source for a wide range of hydraulic equipment.Compared with gear pumps and vane pumps, hydraulic piston pumps offer higher pressure capability, superior efficiency, and variable displacement control. This allows the output flow to be adjusted according to system requirements, achieving energy savings and precise control performance.Hydraulic piston pumps are widely used in various industrial equipment and construction machinery, including CNC machine tools, injection molding machines, press equipment, excavators, construction machinery, and hydraulic power units (HPU). In applications requiring high load, continuous operation, and precise control, piston pumps are one of the most common and critical hydraulic power sources.YEOSHE Hydraulic provides a comprehensive range of hydraulic piston pump solutions, covering high-pressure, medium-pressure, and construction machinery applications. Our main product series include:PV Series Axial Piston PumpsV Series Axial Piston PumpsPVS Series Energy-Saving Hydraulic PumpsAR Series Piston PumpsPVD Series Piston PumpsVD Series Piston PumpsSV Series Piston PumpsP-A10VSO Series Hydraulic Piston PumpsP-A10VO Series Hydraulic PumpsP-A2FO Series Fixed Displacement Piston PumpsPPV Series Piston PumpsConstruction machinery hydraulic pump series include:PVK SeriesK3V SeriesK5V SeriesK7V SeriesPSVD2 SeriesCAT SeriesThese hydraulic piston pumps are widely applied in industrial equipment, machine tools, automation systems, hydraulic power units, and construction machinery, meeting diverse hydraulic system and fluid power requirements.YEOSHE hydraulic piston pumps feature high efficiency, low noise, low temperature rise, and high reliability.

Gear PumpsGear pumps are a type of positive displacement pump widely used in hydraulic systems and industrial fluid transfer applications. They operate by using the meshing action of gears to generate pressure and move fluid efficiently.Gear pumps are generally classified into two main types: external gear pumps and internal gear pumps.External gear pumps consist of two intermeshing gears rotating in opposite directions. As the gears rotate, fluid is trapped between the gear teeth and the pump housing, then carried from the inlet to the outlet. This design offers a simple structure, high durability, and easy maintenance, making it ideal for a wide range of hydraulic and industrial applications.Internal gear pumps use a smaller driving gear rotating within a larger internal gear. A crescent-shaped divider separates the suction and discharge sides, ensuring smooth and continuous flow. This type of gear pump is well-suited for applications requiring low noise, stable flow, and precise fluid delivery.Hydraulic gear pumps are commonly used for transferring oils, hydraulic fluids, and other industrial liquids. They are valued for their compact design, stable flow output, high reliability, and cost-effective performance.YEOSHE Hydraulic Technology provides a wide range of gear pumps in various sizes and specifications to meet different industrial requirements.

Hydraulic Power UnitHydraulic power units (HPUs), also known as hydraulic power packs, are self-contained systems that generate and control hydraulic power. They consist of key components such as a motor, fluid reservoir, and pump, all housed in a compact unit.The primary function of a hydraulic power unit is to apply hydraulic pressure, utilizing hydraulic fluid, to drive various components within a hydraulic system. The pressurized hydraulic fluid is then directed to different hydraulic system components, such as hydraulic cylinders, motors, or other actuators. This pressurized fluid enables these components to perform various tasks like lifting, moving, or applying force. They provide an efficient means of generating hydraulic power, allowing for precise control and automation of machinery and equipment.Trusted Hydraulic Power Unit SupplierYEOSHE takes pride in offering a diverse range of hydraulic power units to cater to your unique needs.
