stainless steel pumps to 75 inch-pounds or enough to seal at maximum
pressure. Do not exceed maximum torque. For Bioclean (PEEK™)
pumps, tighten each check valve firmly by hand. Do not go ¼ turn past
finger tight.
NOTE: The inlet check valve has a larger opening (1/4"-28,
flat-bottom seat) for the 1/8" inlet tubing; the outlet check
valve has a smaller opening (#10-32, cone seat) for the
1/16" outlet tubing. The inlet check valve must be connected
at the larger opening in the pump head. See Figure 5-5.
If the piston and flushing seals have been removed, insert new
seals as described in Section 5.2.3, then continue with Section 5.2.5 to
replace the pump head.
