Internal Gear Pump Market Report 2026

The internal gear pump market size has grown strongly in recent years. It will grow from $0.67 billion in 2025 to $0.71 billion in 2026 at a compound annual growth rate (CAGR) of 6.3%. The growth in the historic period can be attributed to industrial fluid transfer needs, reliance on gear pumps, growth of chemical plants, marine application demand, steady oil and gas operations.

The internal gear pump market size is expected to see strong growth in the next few years. It will grow to $0.89 billion in 2030 at a compound annual growth rate (CAGR) of 5.7%. The growth in the forecast period can be attributed to process automation growth, energy efficiency requirements, hygienic pump demand, expansion of specialty chemicals, equipment modernization. Major trends in the forecast period include demand for high-viscosity fluid handling, adoption in chemical processing, expansion in food and beverage applications, focus on energy-efficient pumps, customization for industrial use.

The growing demand in the oil and gas sector is expected to drive the growth of the internal gear pump market. The oil and gas industry encompasses activities such as exploring, extracting, and refining petroleum products from underground or underwater resources. Growth in this sector is fueled by rising energy demand, geopolitical factors, and technological innovations. Internal gear pumps are critical for the oil and gas industry due to their ability to handle fluids of varying viscosities and temperatures efficiently. Their robust performance and low maintenance requirements ensure reliable fluid transfer in remote and challenging environments, supporting continuous operations across exploration, production, and processing. For example, in December 2025, according to the U.S. Energy Information Administration (EIA), the U.S. had 918,068 producing oil and natural gas wells at the end of 2023. Therefore, the increasing demand in the oil and gas sector is driving growth in the internal gear pump market.

Leading companies in the internal gear pump market are prioritizing the development of innovative solutions, such as the 4-quadrant internal gear pump, to secure a competitive advantage. A 4-quadrant internal gear pump is a type of gear pump with internal gears engineered to function across four distinct phases or quadrants, ensuring steady fluid flow, reducing pulsations, and enhancing efficiency in various industrial settings. For example, in October 2024, Moog Inc., a U.S.-based manufacturing firm, introduced the EPU-G. Moog's EPU-G includes a newly developed 4-quadrant internal gear pump combined with a high-dynamic servomotor, delivering flow rates from 20 to 85 l/min and supporting pressure levels up to 345 bar. Its variable speed, energy-efficient design, and compact structure simplify operation and maintenance while improving machine performance overall.

In December 2023, Atlas Copco Group, a Sweden-based industrial equipment provider, acquired KRACHT GmbH for an undisclosed amount. The acquisition expands Atlas Copco’s industrial pumps portfolio and strengthens its technical capabilities across positive displacement pump technologies, reinforcing its position in fluid handling markets across chemical, petrochemical, and manufacturing sectors. KRACHT GmbH, based in Germany, manufactures high-quality external gear pumps and related fluid handling and dosing systems for industrial applications.
