Thin and mix material thoroughly to a lower
viscosity.
Use a pump system priming fluid (slime). Wet out
the system.
Use a larger diameter hose.
Material is too thick to push
through the hose without
packing out
Hose is too restrictive
Thoroughly mix in a pump-aid or performance
admixture to the material.
