D) Assembling the Mix Injection Pump
Before assembling the mix injection pump, locate all of
the parts that will be required. (See Below)
First install the small oring (#31) onto the pressure
relief plunger (#105) and lightly lubricate the oring.
NOTE: Oring #1126 is slightly smaller than the
other orings used on this assembly. Locate these
orings first and install.
Assemble the connecting tube (#207) with the check
valve (#1126) and orings (#1126) and (#1117). Lightly
lubricate the check valve before installing into the
connecting tube. Lightly lubricate both orings.
Install the two orings (#1126) into the bottom grooves
of the feeding elbows (#32) then lightly lubricate.
Install the assembled pressure relief plunger into the
feed elbows, small end first. Next install the assembled
connecting tube into the mix feed elbow, check valve
first. The feeding elbows are now completely
assembled and can be placed into the bottom of the mix
storage tanks.
To assemble the mix pumps, first locate the pump
gears (#38&A) and pump body (#39). Lightly
lubricate the top, bottom, and inside bore of the gears.
Install the gear into the appropriate gear well. Install
and lubricate oring (#1178) into the pump body (#39).
NOTE: DO NOT lubricate the gear teeth since this is
removed when the pump starts running.
