Liberty Explosion Proof Pumps
Hazardous locations classified under NEC Article 500 (Class I, Division 1 or Division 2) require pumps with explosion-proof ratings to prevent ignition of flammable gases, vapors, or dust. Liberty X-Series explosion proof pumps meet these requirements for sewage and grinder pump applications in gas stations, fuel storage facilities, chemical plants, and industrial sites where volatile atmospheres are present.
Standard pump motors can generate sparks during operation — a serious ignition risk in classified areas. Explosion proof pumps enclose the motor in a housing designed to contain any internal spark or explosion and prevent it from reaching the surrounding atmosphere. Liberty X-Series pumps carry UL listings for the specific hazardous location classes they are rated to operate in.
Before selecting an explosion proof pump, identify the exact hazardous location classification (Class, Division, and Group) from your facility's electrical engineer or site assessment. The pump rating must match or exceed the area classification. Also confirm voltage, phase, solids handling requirements, and discharge size for the sewage or grinder application.
