Frequently asked questions

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.
