The manual hydraulic pump

If you're looking for a portable, versatile solution for working independently, you might be interested in hand-held hydraulic pumps. Although there are various types of manual hydraulic pumps, the hydraulic hand pump is particularly popular for certain types of work. Would you like to buy a manual hydraulic pump for your work, but don't know what to choose? In the rest of this extract, we'll review what you need to know about the special features of manual hydraulic pumps.

What is a hand-operated hydraulic pump ?

Useful in situations where electricity is not available, or a power supply may be dangerous, a manual hydraulic pump is a tool that converts mechanical force into hydraulic pressure to generate hydraulic power.

Hydraulic hand pumps are used in a variety of fields, such as agriculture, construction, mechanical engineering and marine, to provide the hydraulic power needed to perform specific tasks. For example, they can be used to operate cylinders, lift heavy loads and activate hydraulic equipment.

How does a manual hydraulic pump work ?

The operation of a manual hydraulic pump is fairly straightforward and is based on the principle of force exerted by the user. The user has to operate the pump lever several times to generate sufficient hydraulic pressure to perform a given task.

When the user applies force to the lever, it actuates a piston that draws hydraulic fluid into the pump cylinder. Then, when the user releases the lever, the piston pushes the hydraulic fluid to where the pressure is required. This creates hydraulic pressure that can be used to power a variety of applications, such as hydraulic cylinders or cutting tools.

Hydraulic hand pumps can be fitted with different types of piston to generate different levels of hydraulic pressure. Pistons can be single, double or multiple to generate more pressure.

What are the different types of manual hydraulic pumps?

There are several varieties, including single-acting, double-acting and radial piston hand pumps.

- Single-acting hand pumps

They can only be used to exert pressure in one direction, i.e. to move a piston forward, for example. When the user releases the lever, the piston returns to its initial position by gravity.

- Double-acting hand pumps

They allow pressure to be exerted in both directions, enabling a piston to be moved forwards or backwards. This makes them particularly useful for lifting and pushing tasks.

- Radial piston hand pumps

They have a rotating piston that creates hydraulic pressure. They are often used for high-pressure applications and require less effort to operate.

All these hand pumps are available in different pressure and flow capacities, so they can be used in a variety of applications.

What parameters affect the operation of a manual hydraulic pump ?

Several parameters affect the operation of a manual hydraulic hand pump. These include piston size, pump flow rate, maximum pressure, piston stroke and the type of hydraulic fluid used.

The most important is the size of the piston, which determines the pressure the pump can generate. The pump's flow rate is also important, as it determines how much hydraulic fluid the pump can deliver per unit of time. The maximum pressure is the force the pump generates when it compresses the fluid, measured in bars. The piston stroke is the distance the piston travels when the lever or handle is operated.

In fact, when using a hand-held hydraulic pump, it is important to ensure that the pressure and flow rate are appropriate for the task in hand. Too much pressure can damage hydraulic components, while too little pressure may not be sufficient for the task in hand. Similarly, if the flow rate is too low, it can slow down the work process, while an excessive flow rate can cause leaks or loss of fluids.

Other factors such as the temperature of the hydraulic fluid, the quality of the fluid and the level of wear on the pump can also affect pump operation.

What fluid is used in the hydraulic pump?e manual ?

Hand-operated hydraulic pumps can work with a variety of hydraulic fluids such as mineral oil, synthetic oil and water-based emulsions.

In any case, the appliance manual contains information to help you choose the right fluid according to operating temperature, maximum pressure and application requirements.

Oil is preferable for industrial tasks because of its load-bearing capacity and resistance to high temperatures, while water is better suited to light tasks because of its ease of handling.

It is vital to ensure that the fluid used is compatible with the pump, as using the wrong fluid can lead to leaks, loss of pressure and damage to hydraulic components.

How to choose a manual hydraulic pump ?

Choosing the right hydraulic hand pump will depend on the specific application and job requirements. Factors to consider include required operating pressure, pump flow rate, pump size and durability.

Hydraulic hand pumps are available in different pressure ranges, so it's important to choose the pump that can deliver the pressure needed to do the job effectively.

Next, consider the pump's flow rate. You need to make sure that the volume of hydraulic fluid that can be moved by the pump per unit of time is sufficient for the task you want to perform.

Pay particular attention to the size of the pump. Hydraulic hand pumps are available in different sizes to meet the specific needs of each application. Make your choice according to the task you want to perform.

Finally, durability is an important factor to consider when choosing a hydraulic hand pump. Make sure you choose a top-quality pump that will last a long time and withstand regular use.
