bearings
• FEROFORM is ideal for dry start up conditions where lubricating
water may take some time before reaching bearing
• Closer running clearances mean reduced seal wear
Lineshaft and pump bowl bearings
• Long life and low shaft wear
• Can be lubricated with process water as well as oil
• FEROFORM able to survive dry start up conditions or temporary
suspension of water flow
• Closer running clearance means less shaft run out and vibration
Suction cover bearings
• Good wear life even in dirty conditions
• Can be lubricated with process water rather than dedicated grease or
oil supply and so problems with cumbersome lubrication lines are
avoided. |

Vertical Spindle Sump
Pumps |
 |
Shaft support bearings
• Can be lubricated with water or process fluids as well as grease or
oil, reducing problems with lubrication lines during installation
• Able to survive temporary suspension of lubrication during start up or
pump snoring reducing requirements to prime pump and for maintenance
Impeller support bearings
• Close running clearances
• Low wear
• Can run dry temporarily
Wear rings
• Close running clearances improve pump efficiency
• No damage is caused in the case of contact between wear ring and
impeller or casing |

Centrifugal Pumps |
 |
Support bearings
• Low wear rate
• Closer clearances give a stable shaft and lower seal wear
Lantern rings
• Low friction gives ability to survive temporary suspension of
lubrication water
• Dimensional stability allows for closely defined clearances to
regulate water flow
Impeller and casing wear rings
• Low friction and low water swell allows smaller running clearances
giving better pump efficiency |
