Gusher Pumps Pump 1.25×1.5

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

Was the initial fill grease purged if a different grease is used?

Ensure not to over grease to prevent overheating

Ensure bearings do not exceed 225°F

Remove relief from back of ball bearing housing

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

MAINTENANCE — Lubrication / START UP

Measure the ball bearing temperature using a pyrometer

Is the ball bearing temperature within the acceptable range (below 225°F)?

Note any observations about the bearing condition during initial startup

Confirm that the pump is operating normally after approximately 150 hours of service

Apply mounting force against the ring being press-fitted

Ensure no pressure or hammer blows are applied to the other ring

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

Press the shaft through the bearing until seated firmly against the shaft shoulder

Ensure tubing is clean and diameter is slightly greater than the bearing journal

Ensure tubing end is square and contacts only the bearing inner ring

Align shaft with the ram of the arbor press to avoid cocking
