The external gear pump market size was valued at US$ 8.3 billion in 2024 and is expected to reach US$ 11.3 billion by 2031; it is estimated to record a CAGR of 4.8% from 2025 to 2031.

The external gear pump market is segmented into five major regions-North America, Europe, Asia Pacific (APAC), the Middle East & Africa (MEA), and South & Central America. Asia Pacific dominated the market in 2024, followed by Europe and North America and, respectively.

The 100 to 300 bar pressure range represents medium-pressure applications, frequently utilized in industrial hydraulics, chemical processing, and certain high-performance fluid transport systems. This segment demands more robust engineering to withstand increased mechanical stresses, with materials and components specifically selected for durability and corrosion resistance. Pumps, valves, and piping systems in this range must comply with stringent safety standards due to the higher energy content, which increases the risk of equipment failure if mismanaged. Operationally, this pressure range enables more powerful and precise machinery, supporting advanced manufacturing, injection molding, and pressurized chemical processes. Maintenance and monitoring become more critical, requiring trained personnel to ensure system integrity and prevent leakage or rupture. The 100-300 bar segment strikes a balance between performance and complexity, providing higher efficiency and functionality without the extreme technical challenges and costs associated with ultra-high-pressure systems.

External gear pump market future trend: Increasingly, pump manufacturers and end-users are embedding IoT sensors, real-time monitoring systems, and predictive maintenance capabilities into gear-pump designs. This shift allows pumps to communicate operational parameters such as pressure, flow, temperature, vibration, and more - enabling real-time diagnostics, early anomaly detection, and condition-based maintenance, rather than relying on fixed timetable servicing. External gear pumps become "smart pumps," delivering more than fluid movement: they offer ongoing data about equipment health and performance. This trend delivers tangible benefits - reduced unplanned downtime, lower maintenance costs, and extended equipment lifespan.

The ability to perform remote monitoring and diagnostic checks is valuable for distributed installations, difficult-to-access sites, or large-scale industrial installations where manual supervision would be costly or impractical. In recent years, there have been launches of external gear pump series equipped with digital monitoring interfaces, designed for seamless integration into automated industrial systems and smart factory setups. This trend indicates that what was once a fringe enhancement - adding sensors and smart monitoring - is becoming a standard expectation in pump procurement, especially in sectors with high-demand fluid handling (e.g., chemicals, oil & gas, manufacturing, water treatment).
