Spare parts
Critical service spare parts
For critical services, stock these parts, where applicable:
• Intermediate cover (150) and discharge cover (150B)
• Inbound suction cover (182A)
• Impellers (101 through 101M)
• Thrust bearing end cover, outboard (ball bearing construction only) (109A)
• Shaft (122)
• Radial bearing end cover, inboard (ball bearing construction only) (119A)
• Impeller key (178)
• Bearing spacer (217)
• Locating rings (361H and 361F)
An alternative approach is to stock a complete bundle or rotating element. A bundle is a group
of assembled parts that includes everything but the casing. Rotating element is a group of
assembled parts that include all rotating components except the bearings (and parts),
mechanical seals and couplings.
