GENERAL DESCRIPTION
Model LM2250E-X-B Series chop-check grease pump is intended to be
used primarily for grease delivery systems. It uses carbon steel and oth-
er materials which make it compatible with most petroleum based lu-
brication products.
NOTE: If this pump was purchased separately (not part of a system),
consult your sales representative for compatible dispensing accesso-
ries which will best match the application. All accessories must be able
to withstand the maximum pressure developed by the pump.
