Pumpability and slumpability: Pumpability
is the ability of a grease to be pumped or pushed through a
system. More practically, pumpability is the ease with which
a pressurized grease can flow through lines, nozzles, and
fittings of grease-dispensing systems. Slumpability, or
feedability, is its ability to be drawn into (sucked into) a
pump. Fibrous greases tend to have good feedability but poor
pumpability. Buttery-textured greases tend to have good
pumpability but poor feedability.
