(1) Check that any damaged or missing components have been replaced.
The use of petroleum-based lubrications on the seal could cause it to
slip out of place while in use.
(2) Install stationary portion of seal (12) by carefully pushing it into the pump side (6). Be sure the
ceramic seal seat is facing out to mate with the rotating portion of the seal when installed. Wet the
seal with water or saliva as appropriate to aid in assembly but do not use a petroleum-based lubricant.
(3) Install slinger (15) onto motor (9) shaft then assemble motor and pump side (6) being careful not to
damage stationary portion of seal (12).
A drain slot is provided in the bottom of the motor end of the pump
(4) Place motor (9), with pump side (6) installed, onto base (16). Be sure pump side is positioned with
the drain slot pointed down and the motor is positioned with conduit connector pointed up. Align the
mounting holes in the motor, pump side, and base then secure using four new lock washers (14) and
(5) Carefully slide the rotating portion of seal (12) onto motor (9) shaft. Be sure the carbon surface of the
rotating portion is facing toward the ceramic seal seat of the stationary portion.
Shims are supplied and installed in two different thicknesses, 0.005
and 0.010 inch.
(6) Install shims (10, and 11) then install impeller (8). Check axial clearance between the impeller and
pump face. Clearance should be between 0.015 and 0.020 inch. In necessary, remove impeller then
ass or remove shims as necessary to achieve the necessary clearance.
(7) Install preformed packing (7) then slide pump case (5) onto pump side (6). Align mounting holes and
install four new lock washers (4) and screws (3).
(8) Apply sealing compound to threads of plugs (1 and 2) then install plugs.
