A. FACTORY-TOLERANCES.
1. To check pump tolerances loosen the two clamps on pump suction piping and remove inlet elbow.
Through the pump suction hole, insert a feeler gauge between the pump impeller (3) and the suction
cover (1). This measurement on a new pump is between .030-.045" (.762 -1.15 mm).
B. IMPELLER CLEARANCE - TO BRING THE PUMP BACK TO PROPER TOLER-
ANCE, PROCEED AS FOLLOWS:
1 Loosen adjusting cap screws (1B) and push suction cover (1) into casing (5) until suction cover hits
impeller (3). Impeller should be in full contact with suction cover.
2. Tighten cap screws (5B) finger tight. Impeller should rub suction cover and not turn easily through
one revolution.
3. Tighten cap screws (1B) to 15 lb. ft.(165 kg/m).
4. Back off cap screws (5B) 3/4 turn.
5. Tighten cap screws (1B) 3/4 turn (15 lb.ft.(165 kg/m)) and tighten nuts (1N) to 15 lb.ft.(165 kg/m).
6. Tighten cap screws (5B) to 15 lb. ft. clearance gap should be about .040" (1.00 mm). Check to see
if impeller turns freely through one revolution.
NOTE: Tightening of the cap screws should be in a criss-cross pattern.
DO NOT TIGHTEN OVER 15 LB. FT.(165 kg/m). Overtightening
will crack the flange of the suction cover.
C. CLEANING.
1. To clean pump impeller (3), loosen two victaulic pipe clamps and remove suction pipe assembly.
Impeller eye can then be seen through suction cover plate (1) and is readily accessible for cleaning.
2. For further access to impeller, remove the eight bolts (5B) holding cover plate (1) in place. Remove
suction cover plate, being careful not to damage the O-Ring gasket (2).
3. To remove impeller take impeller wrench, which is stored in tool box, and position it so hole is
aligned with any of the eight tapped holes in front of pump casing (5). The 90° leg of the wrench
should face in towards the impeller and be positioned between any two of the impeller fins. Bolt
wrench securely in place with one of the suction cover plate bolts (5B). Using a pipe wrench on the
shaft (9) (See Figure 5 below), unscrew impeller turning shaft in a clockwise direction. Be careful
not to unscrew impeller too far before removing puller wrench.
