Understanding Fluid Pumps: The Heart of Hydraulic Systems

In today’s industrial world, fluid pumps are essential components that power a wide variety of machines and systems. From manufacturing lines to heavy-duty construction equipment, fluid pumps ensure the precise and reliable movement of hydraulic fluid. At AAH Fluid Power, we understand the critical role these pumps play in keeping operations running smoothly, which is why we offer a wide range of new and remanufactured hydraulic pumps from leading brands.

What Are Fluid Pumps?

Fluid pumps are mechanical devices designed to move hydraulic fluid within a closed-loop system. These systems rely on fluid pressure to transmit force and perform work. The pump acts as the heart of the system—drawing in fluid, pressurizing it, and pushing it through valves, cylinders, or motors to generate movement or force.

There are two primary types of fluid pumps used in hydraulic systems: positive displacement pumps and dynamic pumps.

• Positive Displacement Pumps: These pumps move a fixed amount of fluid with each cycle, offering consistent flow and high-pressure capabilities. Common types include gear pumps, vane pumps, and piston pumps.

• Dynamic Pumps: These use velocity to move fluids and are less common in hydraulic systems due to their lower pressure capabilities.

At AAH Fluid Power, we specialize in supplying positive displacement pumps because of their efficiency, reliability, and suitability for demanding industrial applications.

Key Types of Fluid Pumps We Offer

1. Gear Pumps
   These pumps are compact, simple, and ideal for low-to-medium pressure systems. They’re often used in mobile equipment and industrial machinery.

2. Vane Pumps
   Known for their quiet operation and smooth flow, vane pumps are excellent for applications requiring low noise and moderate pressure.

3. Piston Pumps
   Piston pumps are the go-to choice for high-pressure applications. They come in axial and radial designs and offer precision and durability for heavy-duty use.

Whether you’re replacing an outdated unit or upgrading for better performance, AAH Fluid Power provides both new and remanufactured pumps from top brands like Rexroth, Vickers, Denison, Parker, and more.

Why Choose Remanufactured Pumps?

Choosing a remanufactured pump from AAH Fluid Power means you get OEM-quality performance at a fraction of the cost. Each reman unit is completely disassembled, cleaned, inspected, and rebuilt using original parts—or better. Our technicians test every unit to meet or exceed factory specifications, so you can trust your equipment will perform like new.

Remanufactured pumps are a cost-effective, eco-friendly solution that helps minimize downtime without sacrificing quality.
