Hydraulic Components: Impact of Contaminants in Hoses & Pumps

Blog | February 23rd, 2023

Hydraulic pumps offer the required power to run various industrial gear. A faulty hydraulic pump might mean trouble for your business. One of the most prevalent reasons for hydraulic pump failure is contamination. Awareness of the many forms of pollution that might afflict your hydraulic pump is critical. This information enables you to identify contaminants and invest in repairs before your pump suffers irreparable harm.

Contamination from Within

Contamination within your hydraulic pump happens throughout the manufacturing process. Each mechanism and component of a hydraulic pump is machined separately before being assembled by the manufacturer. When burrs or chips left over during machining become free, they cause built-in contamination. Loose burrs and chips will move through your hydraulic pump, cutting the internal pump walls and ruining the sensitive pump seals. A high-quality filtering system connected to your hydraulic pump will readily protect it from harm caused by built-in contaminants. Small burrs and chips that come loose filter out of your pump’s hydraulic fluid before they do irreparable harm.

Contamination That Has Infiltrated

Regular oil changes maintain your hydraulic pump in good working order. Oil changes, however, can also be a cause of pollution. If the fresh oil you put in your pump already has dirt, water, or debris particles, these pollutants will ultimately make their way into your hydraulic pump. Ingressed pollution will damage internal seals and create scoring on your hydraulic pump’s rods and motors. Scoring can potentially reduce your pump’s efficiency, resulting in early failure. Dirt and moisture can enter your hydraulic pump through damaged or loose seals. If you wish to minimise the detrimental consequences of ingressed contamination, only skilled specialists capable of avoiding exposure to outside pollutants should be authorised to execute oil changes or repair defective seals inside your hydraulic system.

Contamination Due to Aeration

Your hydraulic system and air do not mix. Aeration happens when the air becomes trapped inside your machine’s hydraulic hoses and components. This sort of pollution can have disastrous effects on the functioning of your hydraulic gear. Aeration causes the seals in your hydraulic system to dry up and break. Hydraulic fluid leaks caused by damaged seals cause your machines to lose power. The pistons in your hydraulic system are also affected by aeration. Aeration causes the piston heads to round and the pump to become easily damaged. Visual checks regularly can help avoid air pollution. During a visual check, an experienced repair expert can locate any connections inside the hydraulic system that may enable air to enter. A professional can prevent air from entering the hydraulic system through loose or broken intake connections by applying a grease lubricant around these connections at regular intervals.

Contamination by Moisture

Not only may air damage your hydraulic system. Moisture may do the same. Moisture contamination is a risk for industrial hydraulic machinery functioning in a humid work environment. Moisture in your hydraulic system changes the viscosity of the oil. Cavitation or premature pump failure will occur if the oil viscosity is too high or too low. The simplest approach to minimise moisture contamination is to inspect the breathers on your gear frequently. Any moisture in the surrounding environment will be drawn into the hydraulic system by the breathers. Visual examinations of these components regularly allow you to detect moisture issues before they interfere with oil viscosity.

Contamination may be disastrous to your hydraulic system. When servicing your hydraulic equipment, you must be cautious for indications of built-in contamination, ingressed contamination, aeration contamination, or moisture contamination.
