Assembly Instructions:
Clean all parts being reused in parts washing
solvent before reassembly. Remove all remnants
of old gaskets. Rinse and clean pump of all residue
from liquids previously pumped. It may also be
necessary to sandblast corroded components to
remove rust from mating surfaces.
1. Install inlet (18012) and outlet (18008) flanges
with new gaskets (18009 & 18013) as necessary.
2. Replace wear plate (18004) as necessary. It is
highly recommended that the wear plate bolts be
secured with Loctite 241 (blue). Securing the
bolts in this fashion will not allow the bolts to
vibrate loose during pump operation.
3. Install the ceramic/viton seal halves (15035) into
the reservoir (18203A) and cover plate (18202A).
Lubricate the O. D. of the viton seal with
petroleum jelly and install the seal halves into
the bores of the respective components by using
a slight pressure with your thumbs. DO NOT
STRIKE THE SEAL HALVES AT ANY TIME,
OTHERWISE SEAL FAILURE WILL OCCUR.
4. A shim is used to set the clearance between the
impeller and wear plate. Any shim with a
thickness of .030/.040 can be used. An ideal shim
is 1/2" wide piece of No. 21 gauge sheet metal.
