Gusher Pumps Pump CL2×3

MAINTENANCE — Lubrication / START UP

Measure the temperature of the ball bearings using a pyrometer

Is the temperature of the ball bearings below 225°F?

Note any observations about the bearings running tight and hot during initial startup

Record the number of service hours since startup

Ensure pump is shut down before lubrication

Is the pump running at 1750 rpm?

Remove relief from back of ball bearing housing

Fill with grease until fresh grease flows from opening

Is an automatic lubrication system being used?

Place reliefs in the tapped hole (1/8" N.P.T.) if automatic lubrication system is used

Ensure bearings do not run over 225°F

Installation — Impeller Adjustment

Ensure all necessary parts are in place

Verify clearance between impeller and housing or intake flange

Disconnect coupling (#32) and remove sleeve (#32a)

Loosen three locking screws (#57)

Loosen three adjusting screws (#55)

Lightly tap shaft (#1) until impeller bottoms on the intake flange

Tighten three adjusting screws by hand until they touch ball bearing housing

Tighten three adjusting screws just up to the point where the shaft turns freely; then tighten each screw an additional ¼ turn

Apply mounting force against the ring being press-fitted

Avoid forcing the bearing onto a shaft by pressure or hammer blows

Use an arbor press with a face block contacting only the bearing inner ring

Ensure the shaft is pressed through the bearing until seated firmly against the shaft shoulder

Support the shaft beneath the arbor press table if not too long

Use clean, square-ended soft metal tubing for pressing

Align the shaft with the arbor press ram to avoid cocking

INSTALLATION — Coupling Alignment (Chair Mounted Model ONLY)

Verify coupling alignment before and after system start-up

Check Parallel Alignment by placing a straight-edge across the two coupling flanges and measuring the maximum offset at various points around the periphery of the coupling. Realign if offset exceeds .010”.

Check Angular Alignment with a micrometer or caliper. Measure from the outside of one flange to the outside of the other at intervals around the periphery of the coupling. Ensure the difference between maximum and minimum does not exceed .010”.

Ensure all screws are tightened before operating the pump.

Record any additional notes or observations regarding the alignment check.

Adjustment Procedures if Coupling Alignment is Out

Adjust Lateral Parallel Misalignment by loosening the four motor retaining bolts and adjusting lateral screws until alignment is achieved. If misalignment exceeds .020”, proceed to step e.

Adjust Horizontal Parallel Misalignment by loosening the four motor retaining bolts and adding or subtracting shims as needed. If more than 0.1875” total shims are required, proceed to step v.
