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.
