WARMAN PUMP MAXIMUM ALLOWABLE BEARING SPEEDS

The maximum allowable bearing speeds are listed are below for each frame and for standard lubrication utilising Warman recommended greases and oils. G=Greases and O=Oil.

For Recommended Maximum Allowable Pump Speeds, refer to the Information Sheet which takes into consideration the impeller and liner materials and the maximum allowable impeller peripheral velocity.

Allowable bearing speed is influenced by the type of lubrication, loads(radial and axial) and the bearing assembly operating temperature. At higher operating temperatures, re-lubrication intervals should to be shorter.

WARNING:Pump operating within 25% of the maximum bearing speed should generally be reserved for [lightly loaded" applications (eg single stage pumps) to avoid possible lubrication or over temperature problems. High speed multistage applications involving high axial thrust loads should generally be limited to 50~75% of the tabulated maximum speeds.

For further recommendations refer to Warman Head Office-Artarmon.
