Liberty’s XFL50-Series and XFL70-Series explosion proof submersible effluent pumps are designed to move greywater in hazardous locations. The XFL50 Series pumps operate at 1/2 horsepower, with a maximum capacity of 110 gallons per minute and a shut-off head of 39 feet TDH. Liberty’s XFL70 Series pumps operate at 3/4 horsepower, with a maximum capacity of 122 gallons per minute and a shut-off head of 48 feet TDH.
Ideal for effluent transport in refineries, plants, and commercial establishments, these heavy-duty pumps feature cast iron construction, dual shaft seals and a seal fail sensor to ensure reliable performance. Impellers are cast iron except in models marked with “B” which feature bronze impellers. All pumps feature a 2″ FNPT discharge with an option for a 1-1/2″ FNPT threaded discharge flange. Both series are built for operation in Class 1, Division 1 Groups C & D or Class 1, Zone 1 and Groups IIA & IIB hazardous locations.
3-phase models require either ISS-Series or ISD-Series intrinsically safe panels with overloads properly sized for a specific pump model. Be sure to consult our Pump Products team for proper panel sizing.
