Industry Snapshot
Key metrics for the fluid power pump and motor manufacturing industry.
Industry Definition & Overview
Fluid Power Pump and Motor Manufacturing (NAICS 333996) encompasses establishments primarily engaged in producing hydraulic pumps, hydraulic motors, pneumatic motors, and related fluid power drive components that convert mechanical energy into pressurized fluid flow or convert fluid pressure into rotary mechanical motion. Products include gear pumps, axial piston pumps, radial piston pumps, vane pumps, hydraulic gear motors, piston motors, pneumatic air motors, hydrostatic transmissions, and power units combining pumps with reservoirs and filtration systems.
The U.S. Census Bureau[5] identifies roughly 81 active establishments employing an estimated 9,500 workers. Total industry revenue reached $3.8 billion based on Census data, with annual payroll exceeding $644 million. Import competition remains intense, with $4.3 billion in fluid power pumps and motors entering from Germany, Japan, Mexico, and other nations. Production involves precision gear grinding, piston bore honing, valve plate lapping, housing casting machining, and hydraulic performance testing on dynamometer stands.
Per the Bureau of Labor Statistics[6], key occupations include CNC machinists, grinding machine operators, hydraulic test technicians, and mechanical engineers specializing in fluid dynamics. Cast iron, steel alloy forgings, bronze bushings, precision bearings, and high-pressure shaft seals represent primary material inputs for pump and motor manufacturing operations across this sector. Quality standards require close machining tolerances measured in microns, making production equipment investment a critical factor for competitive positioning.

Key Insight: The SBA[7] assigns NAICS 333996 a size standard of 1,250 employees, among the highest in general purpose machinery manufacturing. This reflects the capital-intensive precision manufacturing required for hydraulic pump and motor production. Many domestic producers operate below this threshold and qualify as small businesses for SBA lending programs[8] supporting CNC machining, grinding equipment, and clean room assembly facility investments. Eligible businesses can access SBA 7(a) loans[9] for working capital, equipment, and acquisition financing, while 504 loans[10] support major fixed-asset purchases including real estate and heavy machinery.

Frequently Asked Questions
Common questions about this industry.
What types of businesses manufacture fluid power pumps and motors?
Manufacturers include global corporations producing broad product lines and domestic firms specializing in specific pump or motor types. Some companies focus on high-pressure axial piston pumps for construction equipment. Others build gear pumps for agricultural and industrial applications. Hydrostatic transmission manufacturers combine pumps and motors into integrated drive units. Remanufacturing operations rebuild worn pumps and motors to factory specifications, serving the aftermarket with lower-cost alternatives to new units.
How is the fluid power pump and motor manufacturing industry structured?
The U.S. Census Bureau[5] reports roughly 81 establishments employing about 9,500 workers with industry revenue reaching $3.8 billion. A few large global manufacturers dominate production of axial piston and vane pump product lines. Smaller domestic firms compete in gear pump, power unit assembly, and rebuild market segments. Import competition is substantial, with $4.3 billion in foreign-made products entering the U.S. market from European and Asian manufacturing centers.
What is the SBA size standard for fluid power pump manufacturers?
The SBA[7] sets the size standard at 1,250 employees for NAICS 333996.
