The growth in the historic period can be attributed to increasing environmental awareness, the development of the energy sector, the widespread adoption of hydraulic systems, the global expansion of the oil and gas industry and the rapid growth of the automotive industry.

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 2029 at a compound annual growth rate (CAGR) of 6.9%. The growth in the forecast period can be attributed to rapid industrialization, increased infrastructure projects, the need for hygienic and precise pumping solutions, the focus on reducing operational costs and maintenance downtime in various industries, and stringent regulations and standards for fluid handling systems. Major trends in the forecast period include the growing trend towards offering customizable internal gear pumps, the integration of digital technologies, the need to upgrade and retrofit existing systems, the development and advancement of compact internal gear pumps, and technological advancement in materials.

The increasing demand within the oil and gas sector is anticipated to drive the growth of the internal gear pump market in the coming years. The oil and gas industry is vital, encompassing activities such as exploration, extraction, and refining of petroleum products from underground and underwater sources. Growth in the sector is fueled by factors like rising energy demand, geopolitical factors, and technological advancements. Internal gear pumps play a key role in the oil and gas industry due to their capability to manage various fluid viscosities and temperatures effectively. Their durability and low maintenance requirements are essential for ensuring continuous operations in remote and challenging environments, facilitating reliable fluid transfer across exploration, production, and processing stages. For example, in December 2023, the U.S. Energy Information Administration, a government agency, reported that U.S. oil production was at 11.7 million barrels per day (b/d) in December 2021, with natural gas production (gross withdrawals) at 120 billion cubic feet per day (Bcf/d). By December 2022, oil production rose to 12.1 million b/d, and natural gas production increased to 121.1 Bcf/d. Consequently, the expanding 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 2022, Dover Corporation, a US-based industrial products manufacturer, acquired Witte Pumps and Technology GmbH. This acquisition strengthens Maag's product portfolio in gear pumps, enhancing its ability to cater to diverse industry needs. Witte Pumps and Technology GmbH, headquartered in Germany, specializes in manufacturing gear pumps and related spare parts, further bolstering Maag's market presence.

An internal gear pump is a type of positive displacement pump that operates by the meshing of internal gears. Typically, it consists of two gears, one with external teeth (the rotor) and another with internal teeth (the idler). These pumps are renowned for their capability to handle a wide range of viscosities and maintain efficiency across varying pressure conditions.

The primary product types of internal gear pumps include steel pumps, cast iron pumps, and other variations. Steel pumps are constructed from steel, known for their superior strength and durability. They are particularly suitable for applications involving abrasive or corrosive fluids, as steel provides excellent resistance to wear and corrosion. These pumps operate at different pressure ranges, including less than 100 bar, 100-300 bar, and above 300 bar. They find use across various industries such as chemicals, marine operations, oil and gas, food and beverage processing, and other industrial applications.
