Internal Gear Pump Market is expected to reach US$ 4.0 Billion by 2031

Global Internal Gear Pump Market Forecast to 2031: Key Insights

According to our latest study on "Global Internal Gear Pump Market – Global and Regional Share, Trend, and Growth Opportunity Analysis – by Type, Application, and Geography," the market was valued at US$ 2.9 billion in 2024 and is expected to reach US$ 4.0 billion by 2031. The Internal Gear Pump market size is estimated to register a CAGR of 5.2% during 2025–2031. Surge in materials innovation and fluid compatibility are driving the internal gear pump market trends. 

The majority of the market share is attributable to chemical manufacturing, oil & gas, marine, food & beverage (the fastest growing), and industrial sectors, which require precise placement of solvent, polymer, lubricant, and shear-sensitive Fl-Viewer artificial intelligence interface system [or] fluid pumps.  Technological advancements are aimed at cavitation reduction, IoT, enabled monitoring, hybrid smart designs, corrosion, resistant materials, and compact formats for high, density spaces, along with sustainability through low, emission components and recyclables. Consequently, heavier, duty variants for offshore and hydrogen applications, hygienic stainless, steel models for food/pharma, and digital twins for real, time diagnostics are the trends that dominate to lessen downtime in harsh environments.

Industrial Expansion in Oil & Gas, Petrochemicals, and Chemicals: Global Internal Gear Pump Market Growth

Internal gear pumps handle viscous crudes from shale and deepwater plays without cavitation issues generally associated with centrifugal pumps. Their ability to provide a continuous flow of oil without interruption to producers in the Permian and Vaca Muerta areas has allowed these areas to remain consistently productive. Multiple units of internal gear pumps found in midstream pipeline boosting stations provide pressure to control long-distance transport of heavy and viscous blends of bitumen and dilbit in Canada and Russia. The companies responsible for the production of such products have incorporated internal gear pumps into their operations due to the need for consistent pressure along the length of their pipelines. At the downstream end of the pipeline, internal gear pumps are used in the refinery industry for the transfer of vacuum residuum, asphalt flux, and visbreaker bottoms. As the demand for crude oil is increasing, the demand for internal gear pumps is growing and is the most efficient means for providing feedstock to the hydrotreaters and crackers located at most refineries. With global energy needs increasing, the demand for oil and gas exploration and production is surging, and the IEA expects a substantial increase in oil and gas through 2025. Oil demand is expected to increase by 840 kb/d from 2023 to 2024 to 1.1 mb/d in 2024. Oil consumption is expected to increase to 103.9 mb/d in 2025. Daily refinery throughput and average crude runs will peak at 84.3 mb/d in December 2025 and approximately 3 mb/d higher than at the end of October due to maintenance and the economic downturn during the latter part of 2023. For the two periods, the increase in crude runs per day will be 520 kb/d and 620 kb/d, respectively.

Global Internal Gear Pump Market: Segmental Overview

By pressure, the market is segmented into up to 100 Bar, 100 to 300 Bar, and above 300 Bar. The up to 100 Bar segment held the largest internal gear pump market share, whereas the 100 to 300 bar segment accounted for the second largest internal gear pump market share.

Pumps that operate at a maximum pressure of 100 bar are commonly used in low-pressure industrial, commercial, and utility applications. These pumps are specifically designed for the continuous and smooth movement of lubricants, fuel oils, coolants, and food-grade liquids. They are used primarily in the lubrication cycle, for circulation purposes, and low-pressure hydraulic applications. Reliability and low-noise levels are critical factors in these uses. Internal gear pumps have many advantages due to their compact design, self-priming capability, and ability to handle various viscosity ranges in continuous duty applications under normal operating conditions. Internal gear pumps are manufactured from low-cost materials that provide excellent resistance to corrosion and have long service life, with minimum maintenance requirements. As a result of their forgiving characteristics of operation, systems with pumps that have a maximum pressure of 100 bar offer flexibility in terms of the installation and material options available and have been adopted across a wide range of industries where operational simplicity and cost efficiency are more important than high-pressure capabilities.
