MECHANICAL LEAK
DETECTORS (MLD+ )
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.
HIGHLIGHTS
SPECIFICATIONS
•
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.
• 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.
•
Piston style construction with reduced volume allows the
MLD+ to react quickly and provide more accurate leak
detection capabilities.
• Detects leaks up to 10 feet (3 meters) above the point
of installation
•
A specialised 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.
• 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.
•
Colour 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).
•
240
Compatible with FE PETRO® brand STPs, as well as
competitive STPs and line leak detector housings.
• 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
• Max. liquid viscosity of 70 SSU at 60 °F (15 °C)
• Diesel models (gold cover—MLD+D and MLD+BD) are also
listed for kerosene applications.
