Hydraulic Pumps and Motors

Heavy equipment relies on hydraulic systems to operate different components like the tracks on a backhoe or the bucket on a loader. When a hydraulic unit’s pump or motor becomes faulty, your job site operations and productivity can fall. When you’re in need of fast and reliable Cat® hydraulic parts, Thompson Tractor has what you need to keep your machines running, including.

The Role of Hydraulic Pumps and Motors in Heavy Equipment

A Cat hydraulic system is a fluid-based operation that drives the lifting parts of your heavy equipment. For example, when an operator slightly moves the machine’s joystick in any direction, the hydraulic unit moves attachments like buckets, backhoes, and augers. Hydraulic pumps and motors create enough force and power to operate different lifting parts and even the brakes on certain machines.

Your equipment’s engine drives the hydraulic pumps to transfer fluid through various control valves to the equipment’s actuator. From there, these actuators become pressurized in accordance with the amount of resistance. Pressurized fluid, usually in the form of oil, is forced from one point to another to create motion. The pressure exerted from the oil that moves from one area to the next moves a piston, which moves whatever part it’s linked to.

The Importance of Properly Functioning Hydraulic Parts

Heavy equipment, whether it’s a tracked skid steer loader or a dump truck, fully relies on the hydraulic system to operate at optimum levels. The whole system increases the output of work a machine can perform, helping you complete tasks that would otherwise take days or weeks if performed solely through manpower. Hydraulics have a higher power to force ratio, meaning the force your operators put onto a joystick or other device is minimal compared to the output that can move several thousand pounds.

Cat hydraulic pumps and motors create versatile systems that can operate in multiple directions, giving a single machine many operations, such as lifting, moving, turning, or braking.

Each unit needs a closed and contaminant-free system for reliable operations, so immediate repairs or replacements are vital if your Cat hydraulic motor or pump has a faulty operation, undergoes excessive heat, has poor oil flow, makes odd noises, or reads incorrect pressures. Without a properly functioning hydraulic system, your equipment won’t operate effectively.

We know that safety, uptime, and costs are at the forefront of any heavy equipment operation. Sourcing high-quality hydraulic parts can have a significant effect on your company’s bottom line. Thompson Tractor is here to support you in maximizing your fleet’s uptime while controlling the costs of daily operations.

Types of Hydraulic Parts

Thompson Tractor is here for your entire fleet of heavy machinery, whether you have dozers, excavators, and backhoes, or need grader, wheel loader, or Cat skid steer hydraulic parts. After our solutions are designed and manufactured to fit your Cat equipment, each is tested to meet Caterpillar performance requirements. This ensures Cat equipment meets reliability, productivity, durability, and operating costs requirements. 

The following are types of Cat hydraulic parts you may need for your fleet:

1. Axial and Radial Pistons

Hydraulic piston pumps are what create pressure to push the liquid within a system. Powered by the hydraulic drive, these pistons distribute the energy created by the pressure, causing the fluid cylinder to become pressurized.

An axial piston pump pushes the fluid in a spiral motion like a propeller, while a radial piston generates high pressure by pushing the fluid outward. We offer and can service Cat hydraulic piston pumps.

2. Fluid End

A fluid end’s purpose is to produce a steady pressure of fluid when required by the hydraulic system. They are most subject to stress from the high-pressure environment, so it’s important to maintain, repair, and replace fluid end parts as necessary.

3. Gear

A hydraulic gear pump mechanically delivers a smooth flow of fluid in relation to the speed of the system’s gears. By closing in a fixed volume of fluid, it uses a cyclic pumping movement. A gear pump is a positive displacement pump. We offer Cat hydraulic gear pumps and can perform various services for them.

4. Vane

Vane pumps are like a combination of piston and gear pumps. While they have a limited pressure rating, they operate at a lower pulsation to reduce noise levels.

Electronic controls within the hydraulic pumps and motors allow you to switch between three modes — pressure control, load sense, and flow control. The rugged designs of our piston, fluid end, gear, and vane parts deliver excellent performance and extended life in your heavy equipment operations.
