Hydraulic hammer is defined as a sudden pressure spike that is the result of a sudden stoppage in flow in a pressurized piping system. Hydraulic hammer is exaggerated in a system that utilizes a high pressure fixed speed submersible turbine pump.
A fixed speed pumping system is incapable of changing the flow rate dependent upon demand and as a result, hydraulic hammer is likely to result when flow is interrupted. Hydraulic hammer may result in system fatigue and intensified wear to system components such as diaphragm valves in multi-product dispensers, leak detectors or hanging hardware.
A variable speed submersible turbine pump will provide soft starts and only the pressure required to meet demand which significantly minimize the effects of hydraulic hammer.
The advantages you gain from upgrading from fixed speed to variable speed are undeniable. With Franklin Fueling Systems Variable Speed Conversion Kits you can achieve higher, consistent flow rates, in turn boosting your profits, while eliminating the wear and tear hydraulic hammer can cause.
“Customers expect quick and convenient refueling of their vehicle. FE Petro™ Variable Speed technology provides constant product flow without high pressure and hydraulic hammer. Constant flow means to fill cars faster and a consistent refueling experience at every nozzle,” said Leon Schuster, Product Line Manager for Submersible Pumping Systems.
Installation is easy as each kit comes complete with a variable speed pump motor assembly, MagVFC™ variable frequency controller and four-wire contractor’s plug. All in one variable speed kits are compatible with both FE Petro™ brand 4" Submersible Turbine Pumps, as well as other competitive systems.
The MagVFC™ works with the existing system to increase flow as more fuelling points go live, delivering the flow you need as you need it. Your customers will know the difference between sites that provide steady flow and faster fuelling during peak business hours and those sites that don’t.
