Parts to be replaced on a manual hydraulic pump

Hydraulic hand pumps are used in many applications, including construction, agriculture and industry, due to their ease of use and efficiency. However, like any other piece of mechanical equipment, some parts of the hydraulic hand pump may end up needing repair to keep it working properly. This is why the maintenance and servicing of manual hydraulic pumps are essential to ensure they operate at optimum efficiency. Wondering which parts to replace on a manual hydraulic pump to keep its performance at an optimum level? Find out in the rest of this extract.

How does a manual hydraulic pump work ?

A manual hydraulic pump works by using the manual force of an operator to generate hydraulic energy.

When the operator manually activates a handle or crank, this creates a mechanical back-and-forth or rotary movement, depending on the type of pump.

This mechanical movement drives one or more pistons inside the pump, compressing a hydraulic fluid inside a pump chamber. Compressing the hydraulic fluid increases its pressure, creating hydraulic energy in the form of pressure.

Once the fluid pressure reaches a sufficient level, the fluid is distributed through a system of pipes and valves to a cylinder, hydraulic motor or other hydraulic device to perform a specific mechanical task, such as lifting a load, moving an object or operating a tool.

After it has done its job, the hydraulic fluid is generally returned to the hydraulic hand pump to be compressed again and reused in the process.

Furthermore, hydraulic hand pumps can vary in design and operation depending on the model and the specific application. It is therefore important to refer to the manufacturer's user manual to fully understand the operation of the hydraulic hand pump at your disposal.Top of the form

What parts need to be replaced on a manual hydraulic pump ?

Manual hydraulic pumps are often designed with interchangeable spare parts to facilitate repairs.

And so, it may be necessary to replace certain parts, such as seals, valves, springs, pistons or valves, to ensure that the hydraulic hand pump operates correctly and to avoid potential breakdowns.

The pistons

Pistons are important parts of the hydraulic hand pump. They are responsible for creating the hydraulic pressure needed to pump hydraulic oil. If these pistons are worn or damaged, they can affect the pressure of your pump and make it ineffective. That's why it's important to replace them as soon as you see signs of wear.

The pump body

The pump casing is the part of the pump that contains the pistons and valves.

In fact, the pump casing is an essential component of the hydraulic pump that must be kept in good condition for the pump to work properly.

If it is damaged, it can cause leaks and reduce the pressure of your pump.

Therefore, if you notice any signs of damage to the pump body, it should be replaced.

The tank

The reservoir is one of the essential parts of the hydraulic hand pump. It acts as a container for the hydraulic oil that circulates in the system.

This tank is fitted with a filter to remove impurities from the hydraulic oil.

However, if this reservoir is damaged, your hydraulic pump may not work properly.

So you need to keep it in good condition, or replace it if you find it is damaged.

O-rings

O-rings are small rubber seals found on pump pipes and fittings.

Seals are used to prevent oil leaks. When these seals are damaged or worn, oil can leak out and affect other parts of the pump.

Don't hesitate to replace them when they start to show signs of damage or wear.

Non-return valves

Non-return valves are small devices that prevent oil from flowing backwards through the pump.

Valves are used in many hydraulic applications to prevent leaks and back pressure.

However, when they are damaged or worn, oil can leak out of the pump and can cause your hydraulic pump to malfunction.

The springs

Springs are used in the hydraulic pump to help maintain pressure and piston movement. Weak or broken springs can lead to reduced pump performance, insufficient pressure or malfunctioning pistons, which can affect pump output.

Valves

Valves are components that control the flow of hydraulic fluid within the pump and hydraulic system. Faulty valves can cause disturbances in the flow of fluid, resulting in loss of performance, pressure variations or malfunction of the hydraulic system.

How do I replace the parts in my manual hydraulic pump ?

Replacing hydraulic hand pump parts must be done with care and precision.

If you want to replace the parts of your manual hydraulic pump, you need :

- Switch off the pump and disconnect the power supply ;

- Empty the water tank and clean the pump casing with a clean cloth ;

- Remove worn or damaged parts from the pump by following the instructions in the user manual or by referring to online tutorials ;

- Installing new replacement parts ;

- Fill the water tank to the recommended level ;

- Check the hydraulic pressure with the dial gauge to ensure that the pump is operating correctly.

It's important to note that replacing hydraulic hand pump parts can be complex and require advanced technical skills. If you're not sure you can replace the parts yourself, it's a good idea to contact a qualified professional.

How do I maintain my hydraulic hand pump ?

Regular inspection of its parts and proper maintenance can help extend the life of your manual hydraulic pump. Here are a few tips for proper maintenance:

- Lubricate the pump's moving parts regularly to prevent premature wear ;

- Check the water level in the tank regularly and add water if necessary ;

- Check the hydraulic pressure regularly with a dial gauge to ensure that the pump is operating correctly ;

- Clean the pump casing regularly with a clean cloth to prevent the build-up of dirt and debris ;

- Keep the pump in a dry place, away from dust and moisture.
