Introduction to the hydraulic hand pump

Since it first appeared many centuries ago, the manual hydraulic pump has revolutionised many sectors by enabling fluids to be transferred by generating pressure. This ingenious mechanical tool has evolved over time to become an essential element in many modern industrial applications. Want to find out more about the history of the hydraulic hand pump? The essentials, in more detail.

What are the origins of the hydraulic pump ?

The first hydraulic pump was invented by Archimedes in ancient Greece.

He discovered that water could be used to move heavy loads using a lever pump system.

A lever-operated pump that allowed mines to be drained more quickly and efficiently, contributing to the boom in the mining industry.

How has the manual hydraulic pump evolved over time ?

Since Archimedes' invention, the manual hydraulic pump has undergone many improvements over time.

In the 17th century, the manual piston pump appeared. This pump was more efficient than lever pumps, as it used a moving cylinder to compress and pump the liquid.

In the 19th century, the manual gear pump was introduced. It used a system of gears to transfer the liquid from one side of the pump to the other.

At the beginning of the 20th century, the manual diaphragm pump was developed. This pump used a flexible diaphragm to compress and pump the liquid.

Nowadays, hand pumps have been modernised to include pressure regulation and remote control systems.

What was the manual hydraulic pump used for ?

The hydraulic hand pump has been used in a variety of fields throughout history to power a multitude of tools and mechanical equipment.

In the Middle Ages, this type of pump was used in agriculture to increase land productivity. Water mills, powered by hydraulic pumps, enabled grain to be ground more quickly and efficiently, contributing to the development of agriculture in Europe.

In the 17th century, the hydraulic hand pump was used to supply drinking water to towns and cities. The first water distribution systems were created in London and Paris, using piston pumps to transport water from rivers and wells to the towns' inhabitants.

During the industrial era of the 19th century, the hydraulic pump encouraged the development of drilling machines.

What are the most common applications for a manual hydraulic pump?

Today, these pumps are used in a wide variety of fields.

However, the common applications for a hydraulic hand pump these include the oil and gas industry, mining, precision agriculture, building construction and the marine industry.

In addition, with the advent of advanced technologies such as pressure regulation systems and remote control systems, hydraulic pumps continue to evolve to meet the needs of modern industries.

What are the different types of manual hydraulic pumps ?

Depending on the type of pump action, pumping mechanism, capacity or even application, there are a variety of manual hydraulic pumps.

These include single-acting manual pumps, double-acting manual pumps and lever-operated manual hydraulic pumps.

- The single-acting manual hydraulic pump

Single-acting manual pumps push hydraulic fluid in a single direction. They use a actuator a linear actuator with a single pressure face for pushing hydraulic fluid out of a reservoir and into a hydraulic system.

This type of pump is often used in applications where force is required in only one direction, such as lifting or moving an object.

The double-acting manual hydraulic pump

Double-acting hand pumps can push hydraulic fluid in two directions, using a piston with two pressure faces.

The piston pushes hydraulic fluid out of a reservoir into the hydraulic system when pressure is applied to one side of the piston, and can also push fluid in the other direction when pressure is applied to the other side.

Double-acting pumps are often used in applications such as advancing and retracting a hydraulic cylinder.

The manual hydraulic lever pump

This is a hand pump that uses a lever operated up and down to create hydraulic pressure. The lever is usually attached to a linear actuator that moves inside a cylinder.

When the lever is lowered, the linear actuator moves downwards, drawing hydraulic fluid into the cylinder, while when it is raised, the movable cylinder moves upwards, compressing the hydraulic fluid and producing pressure.

This pressure can be used to operate hydraulic cylinders or motors to perform mechanical work.

How does a manual hydraulic pump work ?

You're wondering how a manual hydraulic pump works ? No need to panic! There's nothing complex about the way it works.

The process of operating a hydraulic hand pump begins by filling the pump body with the liquid to be pumped, such as water or oil. The user then starts pumping, which causes the piston to move in the cylinder.

When the piston moves downwards, it creates pressure in the liquid contained in the cylinder. This pressure pushes the liquid through the pump's outlet valve and into the destination pipe or tank. As the user continues to pump, the piston moves upwards, creating a low-pressure zone that draws liquid through the inlet valve and into the cylinder.

What are the advantages and disadvantages of a manual hydraulic pump ?

The advantages and disadvantages of a manual hydraulic pump are evaluated according to the user's needs, particularly in terms of the pumping power required, ease of use and maintenance, and cost.

Nevertheless, this type of hydraulic pump is useful for users who need a portable pump that is easy to maintain and requires no power source. However, it requires a great deal of physical strength to operate, and its pumping power is limited compared with more powerful electric hydraulic pumps.
