Pumps – Piston

F1/F2

F1 fixed displacement piston pumps • Pressures up to 350 bar (5000 psi)
are widely used on truck applications • High power capability
with operating pressure up to 5000 • Twin flow version available
psi. These lightweight, efficient
pumps were designed specifically for • High self-priming speed
truck applications including cargo • Easy to install
cranes, hook loaders, forest cranes • Easy to service
and concrete mixers.
