Eagle S300

Before starting up the pump, check the impeller centerline submergence. The pump must be full of liquid with specified submergence head above the centerline of the impeller. DO NOT run the pump dry, as this might damage the pump parts or steady bearings.

The type of grease to be used is Shell Alvania E.P.I. Lowtherm or equal. For thrust bearings, approximately 10 shots every 100 hours is adequate. For steady bearings, it is recommended that a self-lubricating bearing such as a carbon be used in place of the metallic bearing. For motor bearings and coupling, follow the manufacturers recommendations.

If a gradual loss in head and/or capacity occurs, performance can be restored by adjusting the impeller. Loosen adjustment bolts and jam nuts. Tighten shell bolts while rotating the shaft until the impeller lightly contacts the suction cover. Loosen bolts until the following clearances are reached between the underside of the bolt head and the bearing shell. S300 pumps – 0.015” plus 0.004” per intermediate bearing and packing. S310 pumps – 0.005” plus 0.004” per intermediate bearing and packing.

Check the following: Speed too low. Discharge head too high. Impeller, suction pipe or strainer completely plugged. Wrong direction of rotation. Air pocket in the suction line. Not enough suction head for hot or volatile liquids. Check carefully as this is a frequent cause of trouble on such service.

Check the following: Shaft bent. Rotating parts bind, are loose or broken. Bearing sworn out. Pump and driving unit misaligned. Impeller burring on suction cover or casing. When connected to electric motors, check whether motor wiring is correct and receives full voltage.
