One of the primary functions of piston pumps in GSE is to provide hydraulic power for equipment such as aircraft lifts, towing tractors, and refueling systems. These pumps are favored in the aerospace industry due to their ability to generate high pressure, reliability, and versatility. Piston pumps can handle a range of fluids, making them suitable for different types of hydraulic systems, including those needed for hydraulic fluid transfer and power generation for various tools and machines used in the maintenance of aircraft.

In the context of GSE, piston pumps are often designed to endure harsh operating conditions. Ground support equipment is required to perform consistently in varied environments, which can include extreme temperatures, dust, and exposure to chemicals. The durability and robustness of piston pumps make them ideal for these applications, as they reduce the risk of failure and ensure the safety and efficiency of ground operations.
Moreover, piston pumps contribute to the overall efficiency of GSE by providing precise control over fluid flow and pressure. This precision is critical when servicing aircraft, as it allows ground crews to execute tasks with accuracy—whether it be during fueling operations or while operating hydraulic lifts. The ability to regulate flow and pressure helps to minimize wasted energy and ensures that operations can be conducted smoothly.
Another important aspect of piston pumps in aerospace GSE is their ease of maintenance. Many modern piston pumps are designed with serviceability in mind, allowing technicians to perform routine inspections and repairs with minimal downtime. This is particularly important in the fast-paced aerospace industry, where quick turnaround times are essential for maintaining flight schedules and operational efficiency.
