GENERAL DESCRIPTION
Model LM2250E-XX-B3 series chop-check grease pump is intended
to be used primarily for grease delivery systems. It uses carbon
steel and other materials which make it compatible with most pe-
troleum based lubrication products.
NOTE: If this pump was purchased separately (not part of a system),
consult your sales representative for compatible dispensing acces-
sories which will best match the application. All accessories must
be able to withstand the maximum pressure developed by the
pump.
