A4% SUBMERSIBLE PUMPING SYSTEMS ^Franklin Fueling Systems I SUBMERSIBLE TURBINE PUMPS Variable Speed Submersible Turbine Pumps Introduced in 1995, FE Petro""brand variable speed submersible turbine pumps (STPs)were the first of their kind for the petroleum equipment industry.With faster fill times during peak hours and power savings during non-peak hours, FE Petro'"brand variable speed STPs allow you to maximize profits while minimizing operating expense.These benefits are something only FE Petro""brand variable speed STPs,the industry's highest performing 4"diameter STPs, can provide. .ems Highlight Higher Flow Rates Minimize Hydraulic Hammer Variable speed systems ramp up the system's Hydraulic hammer is defined as a sudden pressure spike horsepower as needed to provide optimal flow rates at that is the result of a sudden stoppage in flow in a fueling points.This results in faster and more consistent pressurized piping system. Hydraulic hammer can be flow rates at peak business times compared to fixed exaggerated in a system that utilizes a high pressure fixed speed systems. Benefits include: speed STP. • Faster and more reliable flow rates than fixed speed •A fixed speed pumping system is incapable of changing systems resulting in higher throughput at virtually the the flow rate dependent upon demand and as a result, same total cost of ownership. hydraulic hammer is likely to result when flow is • Ramps pressure up and down making nozzles easier to interrupted. squeeze for consistent customer user experience. • Hydraulic hammer may result in system fatigue and • Ramping up and down reduces system wear from line intensified wear to system components such as shock, promoting a longer overall system lifetime. diaphragm valves in multiproduct dispensers, leak detectors or hanging hardware. Efficient Energy Consumption •A variable speed STP will ramp up and down to provide Because a variable speed system is constantly providing only the pressure required to meet demand significantly only the necessary horsepower to achieve desired flow minimizing the effects of hydraulic hammer. rates,the system only consumes as much energy as is needed. Benefits include: Meet Your Flow Rate Needs • Energy savings during non-peak business hours and The STP can be adjusted at installation to perform at a increased flow during peak hours. maximum per-nozzle flow rate of 10 gpm (38 Ipm) based on the specifications of your piping and dispensing system. • Potential for reduced energy costs without sacrificing a faster customer refueling experience. • Depending on peak business requirements, choose from either 2 Hp or 4 Hp variable speed models to meet your desired flow rates. •2 Hp pumps provide constant 10 gpm (38 Ipm) for up to eight fueling positions operating simultaneously. •4 Hp pumps provide constant 10 gpm (38 Ipm) for up to 12 fueling positions operating simultaneously.
