High Performance - FE Petro's 2-stage centrifugal pump design coupled with reliable Franklin motors provides higher heads, faster fuel distribution and lower cost operation. The motors are three-phase operation when the fault is low, and can work at a variety of different voltages. The pump comes standard with a 6" support riser to install the pump into the tank.

Easy maintenance - FE Petro all products are designed with maintenance services in mind, allowing operators to resume operations as quickly as possible during equipment maintenance. The repair of the submersible pump motor assembly can be carried out without an on-site electrician, as no wires are broken. When the extraction part of the pump is moved, large wire diameter pins and sockets provide automatic opening and disconnection of the line. The cam lock without any difficulty has been opened. Easy removal of bolts allows the pump motor to be extracted. Maintain proper clearance to pull out the motor without breaking the submersible pump drain pipe. The pump motor assembly is easily removed from the discharge head by removing the 4 bolts using the standard push bolt head. Replacement submersible motor assemblies can be used with existing Tolken and Red Jacket submersible pumps of the same size.

Reliability - Quality engineering and simple hand-to-hand design work ensure that each high-capacity pump will operate reliably for many years. Continuous-working, three-phase Franklin motors with carbon bearings and stainless steel housing became the industry standard. Molded acetal impellers and hard aluminum-coated diffusers and stainless steel pump shafts ensure unobstructed motor operation when refueling. Dual (180° opposite) 3" transverse drains make installation easy, and two built-in line check valves reduce installation costs. Two line pressure relief valves protect the dispenser, meter and oil line from abnormal pressure under thermal expansion. The pump inlet filter prevents large particles of impurities from entering and the FE Petro high capacity submersible pump is suitable for existing high volume leak detection technology. The new high-capacity submersible pump makes it easy to connect wires in the field without having to disassemble the submersible assembly.

Satisfaction - Every FE Petro submersible pump is rigorously tested and inspected before leaving the factory. Each high capacity pump is performance tested for your tank and buried characteristics and complete assembly to ensure your needs are met. All high capacity pumps are UL listed and meet UL 79 listed requirements.
