Explosion proof pumps are designed to operate in potentially hazardous environments such as chemical plants, mines and oil rigs. Motors and other vulnerable parts are insulated to prevent combustible elements from igniting vapor and causing internal/external explosions. Hazardous locations are defined by the NEC (National Electric Code) and NPFA (National Fire Protection Association). All pumps listed here meet the requirements set by those agencies. Pump Products carries explosion-proof pumps from manufacturers such as Liberty, Zoeller and Goulds.
