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.
