West System 300 Mini Pump
300 Mini Pumps are designed for convenient and accurate metering
of all Group Size A, B and C WEST SYSTEM resin and hardeners.
They mount directly on the resin and hardener containers and
eliminate the mess involved with measuring by weight or volume.
300 Mini Pumps are calibrated to deliver the proper working
ratio with one full pump stroke of resin for each one full pump
stroke of hardener.
300 Mini Pumps Set contains one resin pump and two
hardener pumps. 105/205-206 pumps deliver approximately
0.8 fl oz of resin/hardener with one full stroke of each
pump. 105/207-209 pumps deliver approximately 0.9 fl oz
of resin/hardener with one full stroke of each pump.
As packaged, the pumps are ready to install on the Group Size B
containers. A package of extension tubes for Group Size A
containers is included with the set. Group Size C extension
tubes are included in the 105-C Resin and in the 207-SC or
If necessary, you can combine different group sized-as long as
all of the pumps have a yellow head.
