SUBMERSIBLE
PUMPING SYSTEMS
HIGH CAPACITY LINE
LEAK DETECTOR
The High Capacity MLD product line is based on our standard
STP-MLD unit design. The High Capacity MLD’s compact
design allows installation in the same containment sump as the
submersible pump, greatly reducing the amount of unprotected
leak points between the submersible and the MLD.
HIGHLIGHTS
SPECIFICATIONS
Low Line Restriction
• Detects leaks of 3 gph (11.4 lph) or greater at 10 psi (69 kpa).
Piston design offers the maximum flow rate possible by
keeping flow restriction through the leak detector at an
absolute minimum. Piston has a full 1 7/8" (47.6 mm) of travel
to move the leak detector poppet fully out of the flow path
when product is being pumped.
• Third party evaluated to comply with US EPA requirements
280.41 (B) and 280.44 (A) for continuous monitoring of
pressurized piping systems with maximum of 396.60 gallons
for rigid pipelines, maximum of 95.5 gallons for flexible
pipelines, maximum of 492.10 gallons for combination of
rigid and flexible pipelines.
Faster Installation
• Size: 7¾" × 15" (197 mm × 381 mm).
MLD-HC can be installed after purging air on new installations.
• Weight: 28 pounds (12.7 kg).
Piston Design
• The MLD-HC will remain in the open flow position with
dynamic line pressure at 2 psi (13.8 kpa) at the outlet.
Piston cylinder has 5¾ cubic inches (94.22 cc) of volume to
help minimize nuisance tripping due to thermal contraction
during cold weather.
• Maximum static head pressure without affecting
operation is 12' (3.7 m) from MLD-HC to dispensing point.
MLD-HC Seal
Threads seal using O-rings instead of thread sealant. This seal
design makes for simple installation and removal of MLD-HC
without large wrenches in the tight working environment of the
containment sump.
• Minimum height required from 3" (76.2 mm) NPT port
centerline for top clearance is 9½" (241 mm). Not position
sensitive. Can be installed horizontally to reduce clearance
to 3" (76.2 mm).
• Compatible with all blends of motor fuels including alcohol
blends from 0 to 10% ethanol, 20% MTBE or ETBE with 80%
gasoline, or 17% TAME with 83% gasoline as well as diesel,
fuel oil, Avgas, jet fuel, or kerosene.
• Two models available: STP-MLD-HC for gasoline, STP-MLDHCD for diesel.
Approvals
• Consult factory for applicable approvals.
Quality Certification
• Franklin Fueling Systems is an ISO 9001
Certified Manufacturer.
