Issues Caused by Contamination in a Hydraulic System

Issues caused by contamination in a hydraulic system are generally considered to be of two types: first, the particulate matter that has been picked up and tracked along the system path over time; and second, the actual particulates found in the path of the system. The first type is more common (since it is not as easy to track and remove particulates) but can cause issues as the operator does not always know exactly where things are located in the hydraulic system path. The second type can cause real problems if it is not cleaned up promptly – particulates in the path of a hydraulic system can build up bacteria, algae, and other organic compounds, which can break down and enter the water supply over time, causing a potentially devastating loss of water pressure or the need for expensive chlorine purification.

Contamination of a hydraulic system can also occur when materials, such as cement, are added to the system. This can cause a build-up of lime and reduce the effectiveness of the system. Also, an improperly installed flange or sealing surface on the inside of a pipe can cause the flow of the water to be reduced or stopped completely. For a Hydraulic Power Pack, go to

There are a number of preventative measures that can be taken to reduce contamination of a hydraulic system. These include reducing the amount of debris that can build up in and around the system, including near where the equipment is stored or operated. Contamination of a hydraulic system can often be found by looking for discoloured or murky water; black or dark green stains on the floor near where the equipment is located; or strange noises or smells.
