What materials are used in the construction of a manual hydraulic pump?

When choosing your manual hydraulic pump, it's important to be aware of the construction materials used. Materials play a vital role in the pump's durability, strength and performance. In this article, we'll explore the different materials of construction commonly used to manufacture manual hydraulic pumps. If you've ever wondered how to choose the right hydraulic pump for your application, understanding the characteristics of these materials will enable you to make an informed choice when buying your hydraulic pump.

What is a manual hydraulic pump?

A hydraulic hand pump is a mechanical device used by its user to generate and deliver hydraulic pressure. It is an essential tool in many areas where hydraulic power is required, offering a versatile and portable alternative where electrical power is limited or non-existent.

To understand the materials of construction used in a hydraulic hand pump, it is important to know its basic components and how they work.

Operation of a manual hydraulic pump

In fact, a manual hydraulic pump generally consists of a main body, a piston, a cylinder, a hydraulic fluid reservoir and a control mechanism. When the operator applies force to the piston or control mechanism, this creates pressure in the hydraulic fluid, which is then used to drive cylinders, motors or other hydraulic devices.

Remember that the main body of the pump plays a crucial role in the construction and strength of the device.

Pump body

The pump casing is the main structure of the hydraulic hand pump. It is generally made from strong, resistant materials to ensure its durability and ability to withstand stress. The materials commonly used for the pump casing are :

- Steel : Steel is a material frequently used for its strength and durability. Steel pump casings are able to withstand high pressures and rigorous working conditions.

- Aluminium : Aluminium is a light, corrosion-resistant material. Aluminium pump bodies offer good resistance to stress while being lighter than those made of steel.

Piston and cylinder

The piston and cylinder are essential components of the hydraulic hand pump, responsible for generating hydraulic pressure. The materials used for the piston and cylinder are :

- Stainless steel : Stainless steel is commonly used because of its corrosion resistance and durability. It is ideal for applications requiring contact with hydraulic fluids.

- Hard Chrome : Hard chrome is a coating applied to the piston and cylinder to improve their resistance to wear and corrosion. This coating increases the life of the components and optimises their performance.

Handle and lever

The handle and lever of the hydraulic hand pump are the parts with which the user interacts to operate the pump. The materials commonly used for the handle and lever are :

- Steel : Steel is often used for its strength and durability. It is comfortable to hold and withstands the stresses of pump use.

- Reinforced plastic : Reinforced plastic is used for its lightness and strength. It can be used for ergonomic handles that offer greater user comfort.

What you need to know about the materials of construction of a manual hydraulic pump

Basically, hydraulic hand pumps are the result of a combination of materials specifically chosen to ensure the strength, durability and performance of the pump.

It is also important to note that the materials of construction may vary depending on the manufacturer and the specific model of hydraulic hand pump. It is therefore advisable to consult the product specifications to find out what materials are used. If you don't want to get confused on this point, have a look at the range of products from Au Comptoir and contact us.
