Gear pumps in hydraulics – the first choice for many standard applications<\/h1>

Hydraulic system<\/a>s require a pressure generator. The higher the required pressure, the more powerful the pump used must be. For structural reasons, it is not possible to use the same pumping system for all applications. Available solutions only ever operate optimally within a specific pressure range. The gear pump is particularly advantageous for several reasons. This makes it the pressure generator of choice for many standard applications. <\/p>

Pressure ranges of gear pumps<\/h2>

Gear pumps<\/a> used as pressure generators in hydraulic system<\/a>s operate in a range of 100 – 300 bar. With this performance, they are sufficiently powerful for many stationary and mobile applications. <\/p>

In the brochures of some manufacturers, pressures of up to 500 bar are specified as peak performance. However, this value is irrelevant for the design of a gear pump. Gear pumps<\/a> operated constantly at peak load have only a short service life. The “working performance” is therefore the relevant value. <\/p>

How gear pumps work<\/h3>

The gear pump essentially consists of three parts: the housing and two gears. <\/p>

The volume flow is simply guided through the housing and further conveyed by the two gears. The pump can be driven by any means. Most gear pumps<\/a> are driven by an electric motor or a power take-off (PTO). <\/p>
