Axial Piston Pumps

Axial piston pumps are positive-displacement hydraulic pumps, available in both fixed displacement and variable displacement designs. In fixed displacement pumps, the output remains constant during each cycle, while variable displacement pumps allow adjustment of the displacement chamber geometry to change the flow rate and pressure as required.

With swash-plate and bent axis designs, these pumps are ideal for medium to heavy-duty applications in industrial machinery, mobile equipment, and construction systems.

These advanced hydraulic pumps feature un-load, variable pressure, load-sensing, and pressure-constant controls. Such control accessories allow operators to regulate fluid discharge per revolution and adapt system pressure based on load requirements. This results in optimized performance, power savings, and extended equipment life.

Radial Piston Pumps

Radial piston pumps are widely used in applications that demand high-pressure performance with relatively small flow ranges. These are fixed displacement, valve-controlled hydraulic pumps capable of delivering pressures up to 700 bar and, in some configurations, even 1000 bar. Their robust construction and high efficiency make them ideal for demanding industrial, mobile, and hydraulic system applications.

Key Features (depending on version series)

• Operating pressure: up to 700 bar (1000 bar possible in special variants)
• Displacement: 0.12 to 8.14 cm³/rev
• Speed range: 500 rpm to 3600 rpm

Product Advantages

• High volumetric and mechanical efficiency
• Accurate and fine delivery flow rate gradation
• Extended service life and durability
• Operation independent of the direction of rotation

Radial piston hydraulic pumps are particularly suitable for applications that require precise flow control, high reliability, and compact size. They are commonly used in machine tools, presses, test benches, and heavy-duty hydraulic machinery.

Hydraulic Vane Pumps

Hydraulic vane pumps generate pressure by channeling hydraulic fluid through a set of sliding vanes driven by an off-center shaft. As the shaft rotates, the vanes press against the pump wall, reducing chamber volume and increasing fluid pressure. This pressurized fluid is then directed through the system, delivering consistent flow for efficient hydraulic power transmission.

Vane pumps are available in fixed displacement and variable displacement designs, making them suitable for low to medium pressure hydraulic applications. They are widely used in industrial machinery, mobile equipment, and automotive systems.

Available Variants

• Fixed Displacement Vane Pumps: Up to 210 bar, flow rate 5 – 285 lpm (version-specific)
• Variable Displacement Vane Pumps: Up to 160 bar, flow rate 37 – 270 lpm (version-specific)

Features & Advantages

• Uniform discharge with negligible pulsations
• Low operating noise for quieter system performance
• Extended service life with hydro-dynamically lubricated plain bearings
• Capability to control pressure and flow as per system requirements
• Standardized mounting and connection dimensions for easy integration
• Can be combined with axial piston pumps, gear pumps, and radial piston pumps for system flexibility

Whether you need a compact, quiet, and efficient pump for your hydraulic system, or are exploring different types of hydraulic pumps, vane pumps provide a balance of efficiency and reliability, making them a preferred choice in many industries.

Hydraulic Gear Pumps

Gear pumps are among the most widely used hydraulic pumps due to their simple design, cost-effectiveness, and reliable performance. They operate by the meshing of two gears that force hydraulic fluid around the gears, creating smooth and consistent flow.

Gear pumps are available in two types: External Gear Pumps (using two meshing spur gears) and Internal Gear Pumps (featuring one external and one internal spur gear with inward-facing teeth).
