Gear pumps

Gear pumps are divided into internal gear pumps and external gear pumps depending on the arrangement of the gears. Internal gear pumps are equipped with two co-rotating gears and feature pulsation-free, low-noise operation and pressure ranges up to 400 bar. Main applications are hydraulic power units of medium complexity, stationary industrial applications or in agricultural, forestry and construction machinery. 

By contrast, external gear pumps are equipped with two counter-rotating gears. Manufactured in a modular system, these constant pumps can also be designed as multiple pumps. Because of the competitive price, the high speed and viscosity range, as well as the above-average efficiency in terms of weight, external gear pumps are often used in mobile and simple hydraulic units. The CKD pump range by Bosch Rexroth offers a particularly flexible and powerful pump solution here.

  • Displacement volume: 0.2 – 200 cm³/r
  • Temperature ranges: from -25 °C to +80 °C
  • Maximum operating pressure P max: up to 400 bar
  • Maximum operating speed: up to 4,000 rpm
  • Type of device and design: Constant pump, single or multiple pump, external and internal gear pump, annular gear pump

Axial piston pumps

Axial piston pumps provide a constant or variable volume flow, depending on the speed. pistons whose diameter and stroke specify the amount of oil displaced. A built-in swash plate transfers the rotational movement of the drive shaft into a lifting movement. Axial piston pumps are used universally and even in highly complex hydraulic units. The strengths of these pumps are the controllability of pressure and delivery volume, which also makes them particularly energy-efficient, and high pressures can also be achieved at high flow rates.

  • Displacement volume: 18 – 1,000 cm³/r
  • Temperature ranges: from -25 °C to +115 °C
  • Maximum operating pressure P max: up to 400 bar
  • Maximum operating speed: up to 4,000 rpm
  • Type of device and design: Variable displacement pump or fixed displacement pump, swashplate pump or inclined-axis pump, various control options

Radial piston pumps

Radial piston pumps consists of a large number of valve-controlled pump cylinders. These absorb the rotational movement of the shaft and transfer the force to a piston system. The piston is controlled by a stroke ring or the displacement volume is defined by each revolution. Radial piston pumps can also be used in a wide viscosity range, depending on the specification, and are particularly energy-efficient thanks to their controllability. As constant pumps, they are designed for several pressure outlets and pressures of up to 700 bar. The radial piston pumps are used in units with medium to high complexity, especially in industrial high-pressure applications such as injection molding or injection stamping machines.

  • Displacement volume: up to 250 cm³/r
  • Temperature ranges: from -25 °C to +115 °C
  • Maximum operating pressure P max: up to 385 bar
  • Maximum operating speed: up to 3,000 rpm
  • Type of device and design: Variable displacement pump or fixed displacement pump, single pump or double pump, various control options

Vane pumps

Vane pumps or also rotary vane pumps are usually composed of a hollow cylinder (stator) in which a smaller cylinder rotates (rotor). Its radially movable blades are pressed against the outer stroke ring by centrifugal forces. As a result, sealed chambers are created with increasing (suction side) and decreasing (pressure side) displacement volumes. Because of the low-noise operation, long service life and exceptional energy efficiency at pressures up to 160 bar, vane pumps are primarily used in circulation lubrication systems or hydraulic systems of simple to medium complexity.

  • Displacement volume: 0.25 – 200 cm3/r
  • Temperature ranges: from -25 °C to +80 °C
  • Maximum operating pressure P max: up to 200 bar
  • Type of device and design: Constant pump, with internal admission, single or double stroke, various control modes
Structure and function

The hydraulic pump as the heart of a hydraulic system.

Hydraulic pumps are made of a pump housing, a shaft, seals as well as other displacement components which vary depending on the design. They function according to the displacement principle, in which hydraulic fluid is sucked out of a tank, transported via sealed chambers and conveyed into a hydraulic system. Mechanical energy (speed, torque) is converted into hydraulic energy (volume flow and pressure). The hydraulic pump is driven by a coupling either by an electric motor or a combustion engine.

Contaminated or excessively hot media, incorrect design of your pump, pressure peaks or lack of ventilation during commissioning (required for certain pumps) can accelerate deterioration of the hydraulic pump. Possible consequences are increased leakage or rapid overheating (oil aging). Incorrect design or damage to the hydraulic pump can result in unnecessary energy losses for the system.

When selecting and using your hydraulic pump, it is important to pay attention to the following.

A good hydraulic pump must be designed for the application as well as for the ambient conditions and the operating medium used. Your required sealing and housing materials are decisive for medium compatibility. The displacement per revolution, tolerances, the required pressure range, speed range and volumetric efficiency of the hydraulic pump are important performance parameters. It is also important to consider the individual installation situation and drive type when selecting the pump.

Based on decades of experience concerning the installation, maintenance and repair of hydraulic pumps, we know that high-quality brand pumps last longer. However, your pump does not necessarily have to meet all the above criteria.
