Maintenance and servicing of manual hydraulic pumps

Pompes : quand la maintenance redessine la relation client... - La Revue EIN

If you use a manual hydraulic pump for your day-to-day work, you know how important it is to provide reliable and efficient hydraulic pressure to hydraulic cylinders, cutting and punching tools and lifting equipment. However, without regular maintenance, your pump can suffer premature wear and breakdowns, which can lead to costly delays and problems in your day-to-day work. That's why it's vital to have an idea of the steps you need to take to maintain and service your manual hydraulic pumps, to ensure they work properly and extend their service life. Find out what you need to remember in this extract.

What are the different parts of a hydraulic pump ?

The hydraulic pump is a tool that produces hydraulic energy through piston movement. In fact, before overhauling and maintaining any piece of equipment, it is important to know the various parts that make it up.

When we dismantle this machine, we see that it consists mainly of the pump body, the piston, a spring and valves.

- The pump body

The pump casing is the main part of the pump. It contains the various compression and suction chambers that enable the pump to operate. Generally made of metal, it is fitted with an oil reservoir.

- The piston

The piston is the moving part of the pump. It is the element that is activated by the user to create energy. Often made of metal, it moves inside the body of the pump and is held in place by a spring.

- The spring

This mechanism ensures that the piston returns to its initial position. When the user releases a force on the piston, the spring pushes it back to its initial position. This causes the piston to move back and forth, generating pressure.

- Valves

Valves are the components that enable your equipment to compress and draw in oil. Available in several types, they also regulate the flow of oil through the pump and create the power needed to operate hydraulic equipment.

What tools are needed to maintain manual hydraulic pumps ?

Once you know the main components of hydraulic pumps, it's essential to make sure you have the right tools.

Common tools needed to service non-electric pumps include torque spanners, hydraulic cylinders, pump repair kits, pressure gauges, spare pistons and hose connection spanners.

You can buy these tools in shops selling hydraulic components.

Why maintain and service your hydraulic pump ?

Like any appliance or machine, a hydraulic pump needs care and maintenance to keep it running for a long time. Properly maintained, they can last longer and operate more efficiently than those that are not.

What's more, preventive maintenance can also help you save money by avoiding not only breakdowns, but above all unplanned downtime, high repair costs and reduced productivity.

How do I maintain a manual hydraulic pump ?

To maintain your appliance effectively, it is essential to first take safety precautions to avoid accidents. Make sure it is switched off and that the pressure has been released. Wear safety gloves to avoid injury.

Now that you're in the right frame of mind, you're probably wondering how to maintain a manual hydraulic pump. Well, it's a set of tasks that includes cleaning, lubricating, checking fluid levels and pressures. These tasks may or may not be carried out in succession.

- Cleaning the pump

If you want to keep your machine in good shape for a long time, you'll need to clean it carefully to remove dust, dirt and debris before each use. These can damage internal components or cause oil leaks.

A very effective tip for maintaining your appliance is to use a clean, dry cloth or a soft bristle brush to remove any dirt or debris.

However, take care to avoid using water or solvents to clean your machine, as this could damage its water-sensitive components.

- Lubricating the pump

The smooth running of your machine is nothing other than the result of the quality of the lubrication you apply to it. Mechanical experts agree that lubrication reduces wear on internal components and ensures smooth pump operation. Most new models of non-electric hydraulic pumps require regular lubrication.

If you want to extend the life of your machine, be sure to lubricate the seals, gears, pins and levers according to the manufacturer's lubrication recommendations.

- Checking and adjusting hydraulic fluid levels

Did you know that checking and adjusting your hydraulic fluid levels regularly is essential to ensure the smooth operation and longevity of your pump ?

This is because the liquid is the medium that enables your engine to generate the pressure needed to lift or move a load. If the fluid level is too low, this can not only lead to damage to the pump, but can also affect the overall efficiency of your equipment.

Wondering how to check the fluid level? Well, all you have to do is remove the filler cap on the pump and use a dipstick to measure the fluid level. If the level is below the recommended level, you'll need to top it up until the level is correct.

However, it is vital to use only the type of fluid recommended by the manufacturer, as using the wrong fluid can damage the pump's internal components.

- Replacing hydraulic fluid

Hydraulic fluid is the substance used to power your engine. Like all fluids, it degrades over time and must be replaced regularly to keep your machine running smoothly.

In general, each pump manufacturer gives specific recommendations for the frequency of replacement of this fluid, depending on the pump model. Most pump manuals state that this fluid should be replaced every 12 months or 1,000 hours of use.

When it's time to replace the fluid in your pump, first check the manufacturer's manual for the recommended type of fluid, and drain the fluid reservoir completely. Then slowly add the new fluid using a clean funnel, following the manufacturer's specific instructions. After filling the tank to the recommended level, replace the cap and wipe up any leaks. Finally, start your machine and check that it's working properly.

Once again, we would like to draw your attention to the fact that it is important to follow the manufacturer's instructions to avoid costly mistakes or accidents when replacing the hydraulic fluid in your engine. However, if you are unsure of how to proceed, please call in a professional mechanic to carry out this task.

How do I solve oil leaks on a manual hydraulic pump ?

Seals uif there are any cracks in the pump casing or damage to the hoses and connections, oil may leak into your appliance. It is therefore important to know how to solve oil leaks on a manual hydraulic pump.

If you want to minimise the risk of oil leaks and extend the life of your appliance, make sure you follow the manufacturer's instructions for use. This includes changing the oil regularly and using the correct type of oil.

We also recommend that you handle your hydraulic motor with care to avoid physical damage. This means not exceeding the maximum load capacity and not subjecting the pump to extreme or inappropriate conditions.

Parts to be replaced on a manual hydraulic pump

Maintaining your machine also means regularly checking its various parts and replacing them if necessary. Parts to be replaced on a manual hydraulic pump include seals, oil filters, pressure valves and non-return valves.
