Stripping pump is used to remove contaminated fuel from the bottom of a fuel oil storage tank. It’s designed to draw liquid from the tank’s lowest point where sludge, water, and other heavier contaminants settle. By pumping from the bottom, you purge the tank of dirty fuel before it’s routed back into the system, helping prevent contamination of the engine’s fuel supply. This type of pump is built to handle dirty liquids and operate at low levels, which is exactly what you need for bottom cleaning.

The other pumps have different roles: a transfer pump moves fuel between tanks or from storage to the engine and isn’t specialized for bottom cleanup; a boost pump provides pressure to push fuel through the system; and a scavenging pump relates to the engine’s scavenging process rather than removing contaminants from a storage tank.
