47 SUBMERSIBLE PUMPING SYSTEMS SUBMERSIBLE PUMPING SYSTEMS MLD+ MECHANICAL LEAK DETECTORS FE PETRO ® brand MLD+ mechanical leak detectors provide precise leak detection for standard fuel and biofuel applications on 4" submersible turbine pumps (STPs). This lineup of advanced mechanical leak detectors features reliable line leak detection capabilities and maximum product flow rates. The MLD+ features a compact, yet rugged design to reduce installation height and provide accurate, hassle-free operation. SPECIFICATIONS HIGHLIGHTS • Two models to meet the needs of your standard fuel applications include the MLD+G (blue cover, copper vent tubing) for gasoline with up to 10% Ethanol and the MLD+D (gold cover, copper vent tubing) for diesel with up to 5% Biodiesel. • Two models to meet the needs of your biofuel applications include the MLD+AG (blue cover, stainless vent tubing) for gasoline with up to 85% ethanol and the MLD+BD (gold cover, stainless vent tubing) for diesel with up to 20% Biodiesel or 100% Biodiesel. • Piston style construction with reduced volume allows the MLD+ to react quickly and provide more accurate leak detection capabilities. • A specialized metering pin unique to only the MLD+ provides precision leak detection for any type of pipework system including flexible, rigid or a combination of the two. • Burnished piston chamber provides smooth operation and long service life. • Color coded covers easily identify the model to the application (gold for diesel and blue for gasoline). • Opens completely to allow maximum product flow during fueling operation and remains open with discharge pressure as low as 1 psi (0.07 bar). • Compatible with FE PETRO ® brand STPs, as well as competitive STPs and line leak detector housings. • cULus listed. • Third party certified to comply with US EPA requirements 280.41 (B) and 280.44 (A) for continuous monitoring of pressurized piping. • Consult factory for other applicable approvals. Approvals/Certifications • All models are capable of detecting line leaks equivalent to 3 gph at 10 psi (11.4 lph @ 0.70 bar) when installed properly with the appropriate fuels - all models will signal detection of leaks by restricting product delivery to less than 3 gpm (11.4 lpm) and taking more than 4 seconds to open • All models will remain in the open position during product delivery to manifold, with discharge pressures as low as 1 psi (0.07 bar) - all models will reset to “tripped” when line pressure delay is below 3 psi (0.21 bar) with pump off • Detects leaks up to 10 feet (3 meters) above the point of installation • Max. liquid viscosity of 70 SSU at 60 °F (15 °C) • Gasoline models (blue cover, MLD+G and MLD+AG) are also listed for fuel mixtures containing 20% MTBE, 20% ETBE or 17% TAME with gasoline as well as diesel fuels, fuel oils, kerosene, Avgas, and jet fuels. • Diesel models (gold cover, MLD+D and MLD+BD) are also listed for kerosene applications.
