Liberty’s LSG200-Series Grinder Pumps
meet the demanding needs of com-
mercial and residential sewage appli-
cations where difficult solids-handling
ability is crucial. The LSG200-Series
features a superior cutting system
made of hardened 440 stainless
steel – Rockwell C 58, for shearing
solids into small particles prior to
being passed to the discharge by
the impeller under high pressure.
Applications include individual
or groups of homes, motels,
schools, shopping centers,
lakefront developments and
systems requiring high pres-
sure sewage pumping.
Superior cutting system provides improved
shredding performance over radial cutters.
V-pattern provides up to 108 alternated cuts
per revolution. Entire cutting system made
of 440 stainless steel hardened to 58Rc.
Recessed cutter bolt eliminates wadding
Exclusion cleanout slots and back relief
clears debris from under cutter

internal capacitors and do not
require a separate control panel
for operation. LSG202M-C features
external capacitors, requiring a
panel with appropriately sized
start and run capacitors.
Options for LSG202M-C: External Cap Grinder
