Gears for the hydraulics industry –
precisely manufactured, reliably delivered

Hydraulic systems are at the heart of many industrial applications – and gears are central to this. As an experienced partner, Hänel Precision Gears supports its customers in the development phase and also handles the precise manufacturing of high-precision gears for use in complex hydraulic applications. 

Our solutions are well known for their excellent resilience and absolute reliability.

 

Why high-quality gears
are crucial in hydraulics

In hydraulic systems, gears transmit enormous power and ensure an even distribution of pressure. Precision and material quality are the basis here for reliable and durable operation. Hydraulic pumps, in particular, subject gears to enormous stresses and strains.

Resilience and precision are key factors

A precisely manufactured gear minimizes friction losses, reduces wear, and increases the service life of the entire hydraulic system. 

At Hänel, we combine cutting-edge manufacturing technology with the strictest quality controls to meet these requirements.

The role of gears in hydraulic pumps

The gear plays a pivotal role in generating pressure in every hydraulic pump. The functionality and efficiency

of a gear pump directly depends on the quality of the gears. Our components ensure a constant flow rate and maximum operational reliability.

Precision-engineered gears increase efficiency

An optimally adjusted gear not only improves performance, but also the energy efficiency of your system. It reduces leakage losses, optimizes efficiency levels, and ensures more economical processes – a decisive advantage in times of rising energy prices.

Which industries are particularly dependent on high-quality hydraulic gears?

Industries such as automotive engineering, construction machinery, or the armaments sector rely on our gears whenever resilient hydraulic components are required. Demands in these sectors are high – and our products fulfill them with technical precision.

Frequently asked questions:

What distinguishes a gear pump from a centrifugal pump?
Gear pumps operate according to the positive displacement principle and transport media with a uniform flow rate – even at high viscosity. Centrifugal pumps, on the other hand, rely on centrifugal force, are suitable for high delivery rates, but quickly reach their limits when dealing with viscous media. The choice therefore depends to a large extent on the medium and the intended application.
Which gears are used in pumps?
Gear pumps typically use spur gears or helical gears. Spur gears are more robust, while helical gears are quieter. Internal gearing or other special variants are also used in specialized applications – for example in vacuum pumps – when space and low noise are critical.
What types of pumps are commonly used in industry?
In addition to gear and centrifugal pumps, there are piston pumps, screw spindle pumps, diaphragm pumps, and side-channel pumps. The choice depends on the medium to be conveyed, the pressure range, and purity requirements. Abrasive or chemically aggressive liquids require different solutions than clean water or oil.
What role do gears play in vacuum pumps?
Gears ensure the precise synchronization of the rotors in many vacuum pumps – especially in rotary piston or screw pumps. Even the slightest deviations in tolerance can lead to performance loss or damage. Precise gearing is therefore critical for consistent performance in continuous operation.
What are the key factors when it comes to lubricating gear pumps?
In gear pumps, lubrication does more than just protect against friction – it directly affects the seal between the gears. In many cases, the pumped medium also serves as a lubricant. This requires perfect coordination between materials, clearances, and temperature characteristics, as otherwise the pump efficiency suffers.
How important are low manufacturing tolerances in pump gears?
High-precision tolerances determine efficiency and service life especially in applications with a long lifespan or critical vacuum technology. Cleanly machined gear flanks minimize flow losses and vibrations. Cutting corners here will cost more later in lost productivity or inaccurate processes.
