QUESTIONS & ANSWERS
The EO-30/30-S500B Mini Mule is used to power aircraft hydraulic systems during maintenance and servicing. It allows technicians to operate flaps, cycle landing gear, and perform other hydraulic functions without running the aircraft. This improves safety and efficiency during ground operations. It is ideal for both hangar and field use.
This hydraulic mini mule is designed for use with Skydrol or equivalent phosphate ester hydraulic fluid. Using the correct fluid ensures proper system performance and prevents damage to seals and components. It is specifically built for aircraft that require Skydrol-based systems. Always confirm compatibility before use.
The unit operates using compressed air to generate hydraulic pressure. It connects directly to the aircraft’s hydraulic system through quick disconnects for in-line operation. This allows technicians to safely power aircraft systems without engine operation. A simple setup makes it easy to use in various maintenance scenarios.
The EO-30/30-S500B requires a minimum of 60 PSI of shop air to operate. This air pressure drives the internal pump mechanism to generate hydraulic output. Maintaining proper air supply ensures consistent performance. Higher air pressure can increase output capability within safe limits.
This unit offers an adjustable pressure range from 500 PSI to 3,200 PSI. This flexibility allows it to support a variety of aircraft hydraulic system requirements. Output pressure is controlled by adjusting the air input. Proper setup ensures safe and efficient operation.
The EO-30/30-S500B operates with a 30:1 pressure ratio, meaning the hydraulic output pressure is directly related to the input air pressure. This allows operators to precisely control hydraulic output by adjusting the air supply. The ratio ensures efficient pressure conversion for aircraft maintenance applications. It also helps maintain predictable and consistent system performance.
The Mini Mule can deliver a maximum output pressure of 3,200 PSI when supplied with approximately 108 PSI of shop air. This makes it suitable for high-pressure aircraft hydraulic applications. Operators should always stay within recommended limits. Monitoring pressure helps ensure safe operation.
The unit delivers a maximum flow rate of 2.5 gallons per minute at 300 PSI. As system pressure increases, the flow rate decreases accordingly. This is typical for air-powered hydraulic pumps. The design balances flow and pressure for efficient performance.
As with most air-powered hydraulic pumps, flow rate decreases as output pressure increases. This is a normal characteristic of the system and helps maintain stability under higher loads. The Mini Mule is designed to balance flow and pressure for efficient operation. Understanding this relationship helps operators optimize performance during different maintenance tasks.
This hydraulic pump is compact and lightweight, weighing approximately 28 lbs. Its portable design allows for easy transport between aircraft and work areas. This makes it ideal for both hangar maintenance and field servicing. Technicians can quickly deploy it wherever needed.
No, the unit does not require an inlet air valve, air regulator, or air lubricator. Its integrated design simplifies setup and reduces the need for extra equipment. This helps streamline operations and minimize maintenance. It is ready to use with a proper air supply.
An internal oil accumulator helps reduce pulsation within the hydraulic system. This results in smoother fluid delivery and improved control during operation. Consistent flow enhances system performance. It also helps protect connected components.
Yes, the unit features sparkless operation, making it safe for use around aircraft and sensitive environments. It is built with durable materials, including polymeric seals for long life and efficiency. These features support safe and reliable operation. Proper use further enhances safety.
Polymeric seals provide durability, efficiency, and resistance to wear. They help maintain consistent pressure and reduce internal leakage. This contributes to longer service life and reliable operation. High-quality seals are essential for demanding aviation applications.
Yes, the unit features an integral subplate-mounted air regulator for controlled operation. This allows operators to adjust air input and manage hydraulic output pressure. Integrated components simplify system setup. This improves usability and performance control.
This unit requires hydraulic hoses rated for at least 3,000 PSI working pressure and compatible with phosphate ester (Skydrol) hydraulic fluid. Hoses should be equipped with -8 AN ends, as the mule features 1/2" NPT female ports. Using properly rated hoses ensures safe and reliable operation. Always verify compatibility before use.
