HYDAC Gear Pump Product Catalog
HYDAC Gear Pump Product Catalog (English)
Overview
HYDAC offers a comprehensive range of high-quality gear pumps designed for diverse hydraulic applications, categorized into External Gear Pumps (PGE Series) and Internal Gear Pumps (PGI Series). Both series feature robust construction, low noise operation, and high efficiency, suitable for industrial, mobile, and specialized hydraulic systems.
1. External Gear Pumps (PGE Series)
HYDAC PGE series external gear pumps are available in multiple sizes with narrow-stage specific displacement options and various flange/shaft configurations. They can be combined as multiple pump units (PGE104) for complex applications.
