We offer hydraulic pumps and motors with various designs and setting ranges, covering a wide range of flow from 0.12 cm³/rev to 560 cm³/rev and a normal pressure range of 400 bar and even 700 bar depending on the type of pump selected for an application.
We’re confident we can find the pump that is right for you or that you’re looking for, or, if your existing hydraulic pump is now obsolete, we can help you source its alternate/equivalent. Rexroth hydraulic pumps are renowned for their precision and efficiency, making them a top choice for a wide range of industrial and mobile applications. These high-quality pumps are designed to provide reliable performance under demanding conditions, offering exceptional durability and optimized power delivery. The importance of hydraulic pumps lies in their ability to convert mechanical energy into hydraulic energy, driving the entire hydraulic system. They are crucial in ensuring smooth operation, reducing downtime, and enhancing productivity by providing the necessary pressure and flow required for various machinery. With Rexroth hydraulic pumps, you can rely on advanced technology to improve the overall efficiency and longevity of your hydraulic systems.
Understanding the types of hydraulic pumps and the classification of hydraulic pumps is essential to making the right choice for your equipment.
Whether you need piston hydraulic pumps, or are interested in exploring the different types of hydraulic pumps, we can assist.
Axial Piston pumps are Positive-displacement pumps, available in fixed displacement and variable displacement types. A fixed displacement pump’s output remains constant during each pumping cycle and at a given pump speed, while in a variable displacement pump, a change in the geometry of the displacement chamber changes the output.
These Pumps with their swash-plate and bent axis design satisfy medium to heavy-duty applications in the industrial, mobile, and other industries.
The offered pumps have un-load and variable pressure controls in addition to load-sensing and pressure constant controls. These different compensation control accessories enable us to change the pump’s fluid discharge per revolution. And, also alter the system pressure based on load requirements, maximum pressure cut-off settings, and ratio control. This implies significant power savings.
We offer these pumps with various pressure, flow, and combination control options
- Axial Piston, Fixed Displacement Pump: 400 bar, 27 ….. 950 lpm (depending on the version).
- Axial Piston, Variable Displacement Pump: 500 bar, 32 ….. 1000 lpm (depending on the version).
Axial piston fixed pumps are for open circuit, while variable type pump wherein the flow can be changed by adjusting the swivel angle is used in open and closed circuits.
Radial piston pumps are used for high-pressure and relatively small flows range (operating pressures up to 700 bar). They are fixed displacement, valve-controlled pumps
Features (depending on the version series)
- Operating pressure: up to 700 bar (1000 bar also possible)
- Displacement: 0.12 up to 8.14 cm³/rev
- Speed Range: 500 rpm up to 3600 rpm
Product Advantages
- Very high efficiency
- Fine delivery flow rate gradation
- Long service life
- Operation not dependent on the direction of rotation
Hydraulic vane pumps create pressure by means of flowing the hydraulic fluid through a combination of sliding vanes, and a drive shaft that’s off-center compared to the chamber. As the drive shaft rotates, the internal vanes are pressed against the pump wall and this leads to reduced space which causes an increase of fluid pressure which is then forced out of the pump to other side
These are available in both type of flow displacement - Fixed or Variable and are mainly used in the low and medium pressure range.
We offer
- Fixed Displacement Pump – 210 bar, 5 ….. 285 lpm (depending on the version).
- Variable Displacement Pump – 160 bar, 37 ….. 270 lpm (depending on the version).
Features and advantages
- Provide uniform discharge with negligible pulsations.
- Low operating noise
- Long service life due to hydro-dynamically lubricated plain bearings
- Control of pressure and flow possible
- Mounting and connection dimensions
- Can be combined with axial piston pumps, external and internal gear pumps, and radial piston pumps.
Gear pumps are the simplest, most economical, and most popular pumps, wherein the meshing of two gears forces the fluid around the gears to flow.
These pumps are available as External gear pumps and Internal gear pumps. External types use two meshing spur gears. Internal gear pumps use an external and an internal spur gear with its gear teeth facing inwards.
We offer a wide range of high-powered hydraulic gear pumps manufactured by our principals and associates as per International standards to meet a wide range of industrial, commercial, and mobile machine application use.
We offer Gear Pump as Single and Multiple units with various flange mounting options
- External Gear Pump – 280 bar, 0.25 cc/rev…… 100 cc/rev (depending on the version).
- Internal Gear Pump – 350 bar, 1.70 cc/rev…… 250 cc/rev (depending on the version).
- Special Gear Pumps for High viscosity oil (above 220 CST).
Product Features
- Good mechanical and volumetric efficiency
- Low noise level
- Compact dimensions
- Low weight/power ratio
- Wide range of shafts, flanges, and ports available
These are positive displacement pumps and the unit consists of an inner and outer rotor. The geometry of the two rotors partitions the volume between them into different volumes
Product Features
