NATO Supply Group 43: All About Pumps and Compressors
What is it?
NATO Supply Group (NSG) 43, also known as Federal Supply Group (FSG) 43 in the United States, is a standardized classification system for pumps and compressors used in various applications. It categorizes these essential equipment pieces based on their design, function, and intended use.
What does it include?
NSG 43 encompasses a wide range of pumps and compressors, but it excludes certain types specifically designed for individual equipment. Here's a breakdown of what's included:
- Pumps: These mechanical devices use various operating principles to move fluids from one place to another. NSG 43 covers various pump types such as:
- Centrifugal pumps: Utilize rotating impellers to generate centrifugal force, moving fluids radially outward.
- Positive displacement pumps: Enclose a fixed volume of fluid and then displace it, forcing it through the system. Examples include piston pumps, gear pumps, and diaphragm pumps.
- Submersible pumps: Designed to operate while submerged in a liquid, often used in applications like well drilling or wastewater treatment.
- Compressors: These machines increase the pressure of a gas by reducing its volume. NSG 43 includes various compressor types, such as:
- Reciprocating compressors: Use pistons to compress gas in a cylinder.
- Rotary screw compressors: Utilize rotating screws to trap and compress gas.
- Centrifugal compressors: Employ high-speed impellers to increase gas pressure

- When did the transition from Federal Supply Groups (FSG) to NATO Supply Groups (NSG) occur?
- The transition from Federal Supply Groups (FSG) to NATO Supply Groups (NSG) occurred on January 1, 1997. This change was implemented to align the classification and coding systems used by NATO member countries for military supplies and equipment. Federal Supply Groups (FSG) are now obsolete.
Top 20 Supply Items Included in Federal Supply Group 43
- What is a Reciprocating Compressor? 2307 Items
- A Reciprocating Compressor (COMPRESSOR,RECIPROCATING) is a positive displacement compressor designed to compress air or gas from an initial intake pressure to a higher discharge pressure by means of reciprocating piston(s) in cylinder(s). It is designed to be driven by an independent power source, such as an electric motor, gasoline or diesel engine, or the like. It does not include the prime mover, air storage tank, and the like. It may include various peripheral components, such as drive pulley, unloader, and the like.
- What is a Piston Ring? 3110 Items
- A Piston Ring (RING,PISTON) is a circular, single or multipiece item, metallic or nonmetallic in composition, designed to be fitted in a circumferential groove in a piston and to spring outward against the cylinder wall to function as a seal or wiper. It is supplied in various cross-sectional shapes and is cut through at one point to allow for installation in the piston ring groove. It may include an expander. Excludes PACKING, PREFORMED; RETAINER, OIL SEAL; RETAINER, PACKING; RING, RETAINING; RING WIPER; and SEAL RING, METAL.
- What is a Fluid Filter? 8592 Items
- A Fluid Filter (FILTER,FLUID) is a filter having inlet and outlet connections and designed to be connected in a pipe, tube or hose line. For spin-on, base-mounted filtering devices with integral outer casings, see FILTER ELEMENT, FLUID. Excludes AIR CONDITIONER.
- What is a Fluid Filter Element? 14344 Items
- A Fluid Filter Element (FILTER ELEMENT,FLUID) is a replaceable device designed to remove solid particles from fluids ranging in density from heavy liquids to gases. The removal of particles is accomplished by porous material (metallic or non-metallic), stacked disks, wound wire, or the like, constructed so the fluid can flow through the device while the solid particles are retained. It may be designed to fit into a FILTER, FLUID (or similar cavity), or it may have an integral outer casing and mounting facilities and be designed to connect directly to an engine, compressor, or the like. The degree of removal of particles must be nominally rated at less than 50 microns or absolutely rated at less than 75 microns. Excludes FILTER ELEMENT, AIR CONDITIONING. See also STRAINER ELEMENT, SEDIMENT.
