OPERATIONS & MAINTENANCE
INITIAL ASSEMBLY – GAS ENGINE, C-FACED ELECTRIC MOTOR,
OR PEDESTAL MOUNT
1. Prior to assembly, visually inspect pump outlet for
impeller spacer. Pumps are supplied with a metal shim
inserted into the pump outlet and across the impeller
face to ensure proper impeller spacing.
If the shim is in place, proceed to Step 11.
If shim is missing, begin with Step 2 (Figure 3).
2. Remove two-bolt clamp from pump shaft (Figure 4).
3. Remove (6) nuts and lock washers holding adapter to
pump (Figure 5) .
When removing adapter, be careful not to damage paper
gasket between adapter and pump.
Mechanical seal will be exposed after adapter is
removed. Be careful not to damage seal faces.
4. Gently pry the adapter flange off using a pry bar against
tabs on the adapter (Figure 6).
5. Leave paper gasket on pump over mounting studs. If
gasket is damaged, replace with a new one. Gasket
sealant is not required.
6. Remove impeller, drive sleeve, mechanical seal
assembly.
7. Insert a shim between the impeller vanes and pump
wear plate. A shim 1/2” wide and 0.040” to 0.050” thick is
required. Verify thickness prior to use.
Place shim material into the pump through the outlet
port. Shim material must lie across the wear plate
(Figure 7).
8. Reinstall impeller assembly ensuring the impeller vanes
rest on the shim material.
9. Reinstall adapter flange over mounting studs.
10. Tighten (6) nuts and lock washers (Figure 8).
2” pump – 5/16 x 18 nut – 11 ft.-lbs./ 14.9 Nm torque.
3” pump – 3/8 x 16 nut – 20 ft.-lbs./ 27.1 Nm torque.
11. Install two-bolt clamp over drive sleeve. Be careful to
ensure keyed portion of clamp sits in drive sleeve slot.
Leave bolts and nuts finger tight.
***Some clamps may not have an integral key (Figure 9).
