Main Factors In Hydraulic Pump Failure And What You Can Do About Them

Hydraulic Pump Failure

Hydraulic pumps are used in skid steers and tractors and other farm equipment. The primary role of a hydraulic pump is to produce the energy required by the system for performing different tasks.

Like other machines, hydraulic pumps can develop problems over time and stop working. If you’re noticing a drop in your hydraulic pump’s performance and other signs of hydraulic pump problems, have a professional inspect the device and perform necessary repairs.

Every hydraulic pump owner should know about these common causes of hydraulic pump failure.

Contamination

Airborne particles, debris, and metal parts can enter the hydraulic fluid, contaminating it. Contaminated hydraulic fluid can damage hydraulic pump components and cause them to deteriorate faster. If the hydraulic fluid appears cloudy or milky, water contamination has occurred.

Water in your hydraulic pump can create a corrosive environment, wearing out hydraulic pump components prematurely. Also if air from outside enters your hydraulic pump (aeration) through leaks and loose connections, it can damage the parts of the device.

Overheating

There are several causes of hydraulic pump overheating-from a blocked or clogged filter to low reservoir fluid and lack of maintenance. Regardless of the cause, overheating can lead to oxidation of the hydraulic fluid (which only makes matters worse). It can cause thermal expansion of hydraulic pump components, leading to excessive wear.

Cavitation

Air bubbles can form and eventually implode in the hydraulic fluid, causing cavitation, which can lead to pitting of the pump’s surface. Low hydraulic fluid levels and restricted fluid flow can also lead to cavitation.

Poor Quality Hydraulic Fluid

The wrong type of hydraulic fluid can affect hydraulic pump performance and ultimately lead to pump failure.

Improper System Design

A wrong-size hydraulic system can lead to overloading and premature failure. Incompatible pump components can affect system performance and lead to excessive wear and tear.

Tips to Prevent Premature Hydraulic Pump Failure

Follow these tips to increase the service life of your hydraulic pump.

  • Regularly check the hydraulic fluid to make sure it is clean and free from contaminants. Use high-quality filters to keep debris and dust out of the system
  • Low hydraulic fluid levels can lead to cavitation. Check fluid levels at regular intervals and top up as required
  • High hydraulic fluid temperature can damage the pump components. Ensure good airflow around your hydraulic pump and use coolers if necessary to prevent hydraulic pump overheating
  • Use the hydraulic fluid recommended by the pump manufacturer
  • Periodically check the system’s pressure using gauges. Replace damaged or worn out seals
  • Visually inspect your pump for signs of damage such as leaks. Lubricate components and replace clogged filters

Cessna Hydraulic Pump Identification Guide

Oliver Tractor Cessna Hydraulic Pump

Cessna hydraulic pumps are known for their reliability and superior performance. There are three types of Cessna pumps – gear pumps, piston pumps, and vane pumps. Gear pumps utilize meshing gears, whereas Cessna piston pumps use a series of pistons to pump hydraulic fluid. Vane pumps use a rotating vane (located inside a cavity) to move hydraulic fluid. They produce less noise and handle low-viscosity fluids better.

Over the years, many Cessna parts have been redesigned or replaced. If you own an old Cessna and are having trouble identifying the Cessna hydraulic pump model that powers it, you have come to the right place. Here are some ways to find out the model of your Cessna hydraulic pump.

Locate and Read the Identification Plate

Every Cessna hydraulic pump has an identification plate that contains important information about it, including the model number, a unique serial number (read the serial number of your hydraulic pump to find out its manufacturing date and batch number), and sometimes operational specifications. This information can be used to track the pump’s service history.

Check the Model Number

Every Cessna hydraulic pump is assigned a unique model number according to its capabilities and suitable applications. The model number of your pump can tell you about its flow rate, pressure capacity, and whether it is designed for a light recreational aircraft or a heavier commercial airplane.

Refer to the Manual

Your hydraulic pump owner’s manual contains important information such as pump specifications, usage guidelines, and maintenance recommendations, which can help you assess the pump’s suitability for a specific application.

Examine Physical Characteristics

Cessna hydraulic pumps come in a variety of shapes and sizes. The configuration of ports and connectors of a pump can be very different from that of other models. Smaller pumps are usually designed for single-engine aircrafts. They are less complex than the ones used in larger twin-engine aircrafts. If the identification plate is missing or illegible, observe these physical characteristics to determine the model and type of your hydraulic pump.

Seek Professional Help or Check Online Databases

Contact Cessna’s technical support team or consult a trusted distributor. You can also check an online database or catalog. All you need to do is enter your pump’s serial number to get important information about it. Alternatively, you can refer to online documents (especially if some of your pump’s features are distinctive to it) to learn more about your pump.

Hydraulic.net offers a full range of hydraulic pumps from leading manufacturers, including Cessna, Rexroth, and Dowty. Our products are designed to work in testing operating conditions. To place your order, call (630) 543-7630.

6 SIGNS YOUR HYDRAULIC PUMP NEEDS REPAIR

HYDRAULIC PUMP

Hydraulic pumps are one of the main parts of hydraulic systems. They are known for their durability and ability to work in challenging environments. While hydraulic pumps are complex, their maintenance is straightforward.

Over time, Webster hydraulic pumps can become damaged, affecting system performance. Some common causes of pump damage include lack of maintenance, cavitation, hydraulic fluid contamination, aeration (occurs when air mixes with the hydraulic fluid), mechanical failures, and normal wear and tear.

Why You Should Not Ignore a Damaged Hydraulic Pump

A damaged ultra hydraulic pump may produce more noise or vibrate more violently than usual as it operates and can cause friction to increase. Increased friction can lead to overheating, causing different components to deteriorate faster. A failing pump can lead to further contamination of the hydraulic fluid. Contaminated hydraulic fluid can affect valves, actuators and other pump components.

Warning Signs Your Hydraulic Pump is Failing and Needs Repairs

Hydraulic pumps are usually reliable, but like other machines, they can develop problems over time. It is important to regularly inspect your hydraulic pump and watch out for signs of damage.

If you notice one or more of these signs of pump damage, consult a professional immediately.

  • Unusual Sounds: Strange grinding, whirring or banging noises coming from your hydraulic pump could indicate problems, such as cavitation or bearing failure, affecting internal components.
  • Performance Dip: If your hydraulic system runs slower than usual, one or more of the internal components may have worn out.
  • Overheating: If your hydraulic pump gets too hot as it runs, it could be overloaded. Some other common causes of overheating include inadequate lubrication and a clogged filter. If the fluid in the pump gets too hot, it can become thin, which can cause leaks to occur.
  • Increased Power Consumption: A damaged hydraulic pump may be forced to work harder than usual to maintain pressure and may use more power.
  • Vibrations: Excessive vibration is a sign that the parts of the pump are misaligned or have worn out. Vibrations can also be caused by vapor bubbles that form in the hydraulic fluid.
  • Milky or Foamy Hydraulic Fluid: This may indicate that air has entered the system.

Hydraulic Pump Maintenance Tips

Why wait for your hydraulic pump to develop a problem and then hire a professional to fix it when you can prevent pump problems with proactive maintenance in the first place? Proactive hydraulic pump maintenance is more cost-effective than reactive maintenance and keeps your pump working at its optimum efficiency.

Follow these tips to keep your hydraulic pump in good working order.

  • Regularly check your pump for leaks, unusual noises and vibration.
  • Periodically inspect and change hydraulic filters.
  • Make sure the cooling system is working correctly to prevent overheating.
  • Check the pump and its drive to ensure they’re properly aligned.
