Hydraulic Repair Services

Often it can be easy to tell when your hydraulic system is failing with high temperatures, low pressure readings, and slow operation, but what are the causes of these problems?

• Air and water contamination – faulty pumps, system breaches, or temperature issues can cause both types of contamination.
• Temperature problems – hydraulic systems that operate too hot or too cold can cause severe problems over time. Poor heat dissipation is the usual reason for heat build-up, and environmental factors often cause systems to be too cold.
•  Fluid levels and quality – low fluid levels and inappropriate filtration can lead to air contamination, whilst fluid contamination can cause temperature issues. Using the right type of fluid is essential as certain hydraulic oils are compatible with specific applications.
• Human error – faulty installations, incompatible parts, and improper maintenance or use can result in your hydraulic pump not building pressure.

   

A high standard of care in all aspects of your hydraulic system is key to maximising operational efficiency and reducing your overall costs. A hydraulic repair can be expensive depending on the issue, but it can be avoided with regular maintenance of your parts.

Pumps and motors can sometimes look alike, but a major difference between them is the shaft seal. The low-pressure suction chamber of a pump provides an ideal place to drain pressure away from the inside of the seal. Therefore, most pumps have very low-pressure shaft seals, whereas hydraulic motors usually require higher pressure shaft seals.

If you are experiencing any problems with your pump or motor get in touch with us as soon as possible. When we have evaluated your unit, we can provide a fast and efficient hydraulic repair service to get your system back up and running as quickly as possible to avoid an extended down time in your operation.

The filter should be changed when the pressure drop through it reaches 10-15 PSI. If you don’t have an indicator the typical guide is to change it every 6 months to a year, depending on how much you use it.

The oil should be changed if it starts to look milky due to water contamination, starts to break down (varnish deposits, overheating), or smells like it has burned. Typically, the oil in a hydraulic system can be good for a long time, possibly years, because it isn’t exposed to burning heat like oil in an engine. It is much more important to change the filter regularly, but you can send a sample of your oil to your supplier to find out if your oil is contaminated or worn out.

Friction in the pump, and internal leaking in the pump, valve, or cylinder can all create some heat. Also, the power needed to push oil through various passages and holes in the valve, hoses, and fittings makes it hotter. Hydraulic motors running constantly usually generates a lot of heat as well, so there are a few things to be mindful of when you think your system might be overheating. 

As any plant owner or user of hydraulic plant equipment knows, when equipment fails every minute it is out of operation is potential revenue lost and the problem must be addressed as fast as possible. Due to the complexity of the equipment user repairs are impossible and should only be attempted by experts to avoid the chance of further damage to the equipment, putting it out of service for even longer and costing even more in lost revenue and repair costs. Also attempting repairs without the necessary training and technical equipment is extremely dangerous and could put the individual at risk of severe physical injury or even death, an outcome no employer wants to risk. 

Efficient 

Arranging the transport of broken or damaged hydraulic unit from the worksite to a repair firm can be inconvenient to arrange, especially if the worksite is remote or difficult to access area. For example, in forestry work, quarrying, mining and similar work the worksite will by its very nature be off the beaten track and have no local repair firms. Metalworking plants, scrap metal and recycling companies or any large warehouse or factory will often have large fixed pieces of machinery that cannot be removed.  This adds to downtime and as even one piece of equipment rendered inactive can slow down the entire team or bring work to a complete stop, time is of the essence. 

Cost Effective 

As many repair services will then need to source spare parts before repairs can start or replacement parts if a unit is damaged beyond repair, further time can be lost. Even if a qualified and experienced engineer who can perform the necessary repairs is present, sourcing and acquiring specialist parts as quickly as possible with the minimum cost to the business is paramount and a reputable repair company will be able to offer advice on whether this is best course of action. Ideally the repair service will maintain a stock of parts to avoid this or even offer service exchange units or reconditioned and new units to make the process smoother and more efficient even when equipment is beyond repair.  

Experienced

Obviously, any customer will want to use a professional company with a proven track record and competent, highly trained staff who can guarantee the quality of their work and provide quality aftercare service for peace of mind should any further problems arise. Assurances that any repairs bring the plant or equipment back up to OEM standards should also be sought so the customer can be sure their equipment is functioning to the most safe and efficient standards.

Free inspection –  

Once your part arrives, it will be carefully dismantled and inspected and wear tolerances will be measured and compared to manufacturers specifications at no cost. 

No obligation quote –  

Following our inspection and evaluation we provide the customer with a report of our findings and a competitive quote for repairs with no obligation to accept. 

Second inspection –  

Once our quote is accepted by the customer, all parts are meticulously cleaned first with a machine hot wash then by hand to ensure total cleanliness. This also allows a second inspection by experienced repair staff to ensure no damage has missed. 

Comprehensive repair process – 

Once we are sure the unit and all its components have been inspected as fully as possible, all damaged and worn parts are replaced. All O-rings, seals and bearings are also replaced and the unit is completely rebuilt. 

Full post repair testing –  

All hydraulic pumps are then tested to ensure they function fully to manufacturers specifications. 

Custom testing rig –  

To ensure our customers receive the optimum performance from their equipment on its return we have invested in custom built hydraulic testing equipment unique to our facility to be certain we deliver the best results. This means our hydraulic testing can be performed at various speeds and pressures to simulate the actual working conditions the part will be subjected to when working in line with OEM standards. All fluids used are filtered to ensure purity and prevent any contamination at the last stage. 

Full warranty –  

Once work is completed, we offer a twelve month written warranty giving worldwide cover and excellent after sales care to guarantee customer satisfaction.
