Booster Pump Reassembly
1. Clean seat cavity of the volute bracket thoroughly.
2. Thoroughly clean pump shaft. Assure that the shaft is not grooved and that there is no evidence of pitting or
fretting. If the shaft is grooved, fretted, or worn, replace it.
3. Install the pump shaft onto the motor shaft. Ensure all debris and burrs are removed from the motor shaft.
4. Place the volute bracket on a firm surface with the seat cavity (pump end) up. Then place a small amount of
vegetable oil on the seat cup or o-ring seat. Place the seat in the cavity with the polished face up toward the
pump end. Evenly push seat into cavity with fingers then gently tap seat into place with a wooden dowel or
plastic rod (1 - 1/8” outside diameter / 28 mm). To help ensure the seat is not damaged, place the cardboard
disk supplied with the seal over the seat face.
5. Place volute bracket on motor (aligning the base if applicable). Secure volute bracket with four motor bolts.
6. Pull pump shaft forward until shoulder of pump shaft contacts back of volute bracket and slightly snug one
setscrew to hold shaft in place.
7. Install seal head assembly
a) Lubricate shaft and elastomer with vegetable oil.
b) Install rotary seal head onto pump shaft and slide toward seat until carbon face touches seal seat.
c) Install seal spring and retainer.
d) Thread impeller onto pump shaft ensuring that the spring retainer does not slip between the shoulder of the
shaft and the hub of the impeller. Install locknut with small amount of removable loctite. Hold shaft with
locking type pliers (vice grips) and tighten impeller locknut.
e) Loosen pump shaft setscrew.
f) Install new volute cover gasket and mount volute cover. Secure with bolts and tighten evenly.
g) Slide pump shaft forward until impeller touches volute cover. Slide shaft back with a screwdriver .010 - .015”
(0.254 - 0.381 mm). Tighten pump shaft setscrews. Rotate shaft by hand to ensure impeller does not rub
against volute cover.
8. Return pump to installation and reconnect electrical connections.
9. Start pump momentarily to observe shaft rotation. If rotation corresponds to the rotation arrow, pump may be
put into service. If rotation is incorrect, refer to the wiring diagrams within this manual.
