Spare parts
Critical service spare parts
For critical services, stock these parts, where applicable:
• Impellers (101 through 101M)
• Thrust bearing end cover, outboard (ball and sleeve bearing construction only) (109A)
• Shaft (122)
• Radial bearing end cover, inboard (ball bearing construction only) (160)
• Impeller key (178)
• Bearing spacer (217)
• Snap ring (361F)
• Locating ring (361H)
An alternative approach is to stock a complete rotating element. This is a group of assembled
parts that includes all rotating components except the bearings (and parts), mechanical seals,
and coupling.
Recommended spare parts
When ordering spare parts, always state the serial number, and indicate the part name and
item number from the relevant sectional drawing. It is imperative for service reliability to have a
sufficient stock of readily available spare parts.
Stock these spare parts, where applicable:
• Cartridge mechanical seal
• Thrust bearing (duplex pair) (112A)
• Oil rings (114, 323)
• Sleeve bearings, two (117) (sleeve bearing construction only)
• Throttle bushing, sleeve (128)
• Throttle bushing (129)
• Bearing locknut (136)
• Stage ring (144)
• Center bushing (155)
