Common types of Yuken Hydraulic Pumps

What is a Hydraulic Pump?

The hydraulic pump is a very common device in several spaces, especially industries, as it provides the transformation of potential energy into kinetic energy. It seems confusing, but its use and operation are simpler than people imagine when maintenance care is kept up to date.

Hydraulic pumps are considered as fluid machines because their mechanical system can exchange energy with the fluid they contain. Some common examples of Hydraulic pumps are compressors, water turbines, fans, and steam turbines.

What is a Yuken Hydraulic Pump?

Founded over 90 years ago, Yuken started in an automobile repair shop founded in 1929 by Uichi Yuki in Tokyo. By 1940 the repair shop had become a successful manufacturer of hydraulic equipment, producing hydraulic honing machines, hydraulic vane pumps, and hydraulic control valves. For this reason, Yuken is a worldwide leading brand in the production of Yuken pumps. Yuken is one of the most highly professional and experienced companies for the sale and installation of hydraulic pumps all over the world.

Yuken hydraulic pump is powered by some source of energy, such as gas or even electricity, but this varies and it depends on the type of equipment used. Therefore, it is certain that the Yuken hydraulic pump can benefit several industrial sectors when chosen according to the needs of the same.

Types of Yuken hydraulic pumps

Each type of Yuken pump has its own advantages and disadvantages. These pumps contain some components that are common in all hydraulic pumps. Each type is manufactured to work within a specific pressure range. When using hydraulic pumps, precautions must be taken to reduce the risk of injury.

Many different types of hydraulic pumps are available to consumers. The most commonly used types of Yuken hydraulic pumps are gear, vane, axial piston, radial piston, and gerotor pumps.


Several components are part of any hydraulic pump. These main components are the reservoir, valves, pumps, and actuator. The major functions of a hydraulic reservoir are to maintain a given volume of liquid, transfer heat, allow contaminants to settle, and facilitate the release of air and moisture from the liquid. Pumps displace the volume of liquid against resistant loads or pressures. The valves start and stop the device as well as direct the flow of liquid. Actuators convert hydraulic energy back into mechanical energy.

Benefits of Yuken Hydraulic Pumps

Each type of Yuken pump offers several benefits. Gear pumps and vane pumps are generally considered simple and inexpensive. Vane pumps are good for higher flow, and low output pressure. Axial piston pumps include a variable displacement mechanism that allows you to automatically control pressure control. Radial piston pumps are typically used at high pressure and low flow. The gerotor pump is very efficient at medium pressure.


Let’s consider some aspects of Yuken hydraulic pumps before putting them to use. Vane pumps are the least efficient as they work at a constant displacement. Axial piston pumps are at a disadvantage as they are more sensitive to oil contamination than many other Yuken pumps.


Different Yuken pumps are manufactured to produce a maximum level of pressure. The “bar” is a unit of measurement used to measure pressure, 1 bar is equivalent to 100,000 newtons per square meter. Gear pumps and vane pumps are suitable for producing pressures above 200 bars. Axial piston pumps can produce pressures of around 350 bars. Radial piston pumps can produce pressures of up to 650 bars.


Yuken is a well-recognized company in the world. They are known for high-quality products and top-notch service. When it comes to the hydraulic pump, Yuken Pumps catalog is composed of models that serve several establishments and, above all, all equipment has a guarantee of efficiency. So, if you want to buy a hydraulic pump purchase it from Yuken hydraulic pump.
