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
Line Leaks
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 leaks by restricting
product delivery to less than 3 gpm
(11.4 lpm) and taking more than
4 seconds to open
Delivery and
discharge pressure
All models will remain in the open
position during product delivery to
manifold, with discharge pressure
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
• Burnished piston chamber provides smooth operation
