Applications in Heavy Equipment

Main hydraulic pumps are essential for powering critical machine functions such as lifting, digging, and driving. Imara’s aftermarket and OEM pumps are trusted in industries including construction, mining, agriculture, and infrastructure. By maintaining optimal hydraulic pressure, our pumps keep your machinery efficient, reliable, and productive under the toughest workloads.

Main hydraulic pumps operate by moving oil and other fluids through the system to provide the necessary force for heavy machinery. The quality and characteristics of these fluids, such as viscosity, are crucial for proper lubrication and performance. Seals and bearings are key components that help maintain pump efficiency, prevent internal leakage, and reduce wear and contamination. Regular inspection and maintenance are required to ensure all components—including seals, bearings, and other internal parts—are functioning properly, especially in demanding industrial applications like paper mills, steel mills, recycling plants, oil & gas, and mobile equipment. This helps extend equipment lifespan and maintain optimal efficiency.

Order with Confidence

When you choose us, you get more than just main hydraulic pumps — you get peace of mind. All our pumps are rigorously tested for durability, backed by fast worldwide shipping, and supported by dedicated technical experts. Place your order today and keep your fleet running at peak performance.
