Is Your Emergency Generator Drawing from the Sludge Zone?
Eliminate the greatest failure point in mission-critical fuel storage.
Why Standard Generator Belly Tanks Fail Under Load
Belly tanks are designed for structural support, not fuel cleanliness
Internal baffles create dead zones where water and biomass settle
Fixed pickups draw fuel from the most contaminated layer
During emergencies, high-demand suction entrains particulates or free water from the bottom strata, leading to rapid filter plugging and subsequent engine starvation.
In mission-critical environments, this is not a minor inconvenience — it is a system vulnerability.
Restricted access limits effective cleaning
Structural baffles create dead zones
Water and biomass accumulate below baffles
How Floating Suction Works
TopFLO® floating suction systems position the fuel pickup in the cleanest fuel layer — above settled water and microbial growth.
A sealed float automatically tracks fuel level changes, maintaining pickup position in the clean fuel zone during:
Startup
Load acceptance
Extended runtime
High-demand operation
Instead of drawing from the most contaminated portion of the tank, the system consistently pulls from the cleanest available fuel layer.
Performance Benefits
Reduced Failure Risk
Prevents water and sediment from entering generator fuel systems.
Lower Maintenance Costs
Reduces clogged filters, injector wear, pump strain, and service calls.
Reliable Fuel Flow
Maintains steady flow during high-demand operation and extended runtime.
Designed for Mission-Critical Facilities
TopFLO floating suction systems are ideal for:
Hospitals and healthcare campuses
Data Centers
Emergency response centers
Government Buildings
Utilities and infrastructure sites
Any facility relying on sub-base generator tanks
Where power reliability is non-negotiable, fuel quality must be protected.
