Boulden - Vertically Suspended Pump Shaft Bearings

What to do to Get the Most Out of Your Vertical Pump Shaft Bearings

• Replace existing bearing materials with engineered composite materials
• Keep the original design bearing clearance
• Make sure the pump overhaul results in good rotor concentricity. The rotor should turn freely after assembly.
• Vertically suspended pumps generally use rigid couplings. There should be a second check after coupling to make sure the rotor still turns freely to avoid coupling-induced shaft misalignment.

• Greater tolerance of dry-running at start up compared to traditional materials
• Low wear and long life
• Durable material that does not break from mechanical or thermal shocks compared to carbon-based materials
