SEAFLO (legally SeaFlo USA / SEAFLO North America) is a privately held manufacturer founded in 2004 and headquartered in South Bend, Indiana, specializing in marine, RV, industrial, and agricultural parts and accessories. The company's core product lines include diaphragm pumps across five series (21, 31, 33, 41, 51) offering flow rates of 1.0-6.0 GPM and pressures of 35-120 PSI; bilge pumps (1000-2200 GPH); macerator pumps; bilge blowers (300-500 CFM); and DC submersible deep well pumps with up to 230 feet of lift.

The company employs more than 260 individuals including 16 engineers and operates a semi-automated manufacturing process spanning mold design through production and testing. It holds more than 30 national patents, including a pending Watertight-Gland Quick Disconnect Design, and maintains CE, RoHS, and ISO 9001:2008 certifications along with memberships in the National Marine Manufacturers Association (NMMA) and American Boat and Yacht Council (ABYC). Product differentiation centers on self-priming pumps capable of running dry, built-in pressure switches for automatic demand operation, corrosion-resistant construction, and a 4-year warranty on washdown kits.

SEAFLO distributes products through a vetted authorized dealer network spanning the United States, Canada, Central America, South America, and the Caribbean (Barbados, Puerto Rico, Venezuela), supplemented by direct wholesale accounts. The company does not publish pricing publicly; wholesale access is granted after an application and vetting process.

Leadership consists of CEO John Kosowski, with no other management team details disclosed.
