Gusher Pumps Pump 1.5×2

Shut down pump prior to lubrication

Ensure no mixing of grease types (e.g., lithium/oil base)

Ensure initial fill grease is purged if using alternative grease

Ensure bearings do not run over 225°F

Remove relief from back of ball bearing housing

Fill with grease until fresh grease flows from opening

If using automatic lubrication system, ensure reliefs are placed in the tapped hole (1/8" N.P.T.)

MAINTENANCE — Coupling Alignment

Verify coupling alignment schedule

Adjust Lateral Parallel Misalignment

Adjust Horizontal Parallel Misalignment

Adjust Lateral Angular Misalignment

Adjust Horizontal Angular Misalignment

MAINTENANCE — Lubrication / START UP

Measure the temperature of the ball bearings using a pyrometer

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

Record any observations about the initial startup behavior of the bearings

Confirm that the pump operates normally after approximately 150 hours of service

Measure and record the discharge pressure

Measure and record the flow rate

Measure and record the motor amp draw

Describe the location of the pressure gauge in relation to the liquid level

Verify if the mounting plate height is at least 1" above the highest possible liquid level and securely mounted

Check if the liquid level is at least 2" above the point where the shaft exits the top of the pump end

Test if the shaft rotation is clockwise when viewed from the top by momentarily energizing the motor

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

Tighten locking screws (#57) and jamb nuts (#56)
