Gusher Pumps Pump 2.5×3

MAINTENANCE — Lubrication / START UP

Check ball bearing temperature using a pyrometer

Is the ball bearing temperature below 225°F?

Note if bearings seem to run tight and hot upon initial startup

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

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)

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

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

Test shaft rotation for clockwise direction

Remove four motor retaining bolts

Break welds loose that hold discharge pipe cover plate to mounting plate

Remove bolts & nuts that hold discharge pipe to impeller housing

Chair and Drive Motor: 52VHD Power Frame

Ensure pump is shut down before lubrication

Verify no mixing of grease types

Ensure initial fill grease is purged if using alternative grease

Avoid over-greasing to prevent overheating

Ensure bearings do not exceed 225°F

Remove relief from back of ball bearing housing
