Consider the level of control you need and choose a power pack that offers the right balance of simplicity and functionality.
Types of Diesel Driven Hydraulic Power Packs
Open Loop vs. Closed Loop Systems
Open loop systems are simpler and more cost-effective, making them suitable for general-purpose applications. They allow the hydraulic fluid to return to the reservoir after use. Closed loop systems, on the other hand, recirculate the fluid within the system, offering better efficiency and control. For tasks like operating a concrete core drill stand, an open loop system may be adequate. However, for precision tasks with portable hydraulic rescue tools, a closed loop system is often preferred.
Fixed Displacement vs. Variable Displacement Pumps
Fixed displacement pumps deliver a constant flow rate, making them ideal for applications with consistent demand. Variable displacement pumps, however, can adjust the flow rate based on demand, offering greater flexibility and energy efficiency. For example, a concrete core drill stand may benefit from a fixed displacement pump, while portable hydraulic rescue tools may require the adaptability of a variable displacement pump.
Mobile vs. Stationary Units
Mobile units are designed for portability and are ideal for fieldwork, such as construction sites or rescue operations. They are typically compact and lightweight, making them easy to transport. Stationary units, on the other hand, are built for fixed installations and are often more powerful.
