6.6.11.4 Spare parts
Critical service spare parts
For critical services, stock these parts, where applicable:
•
Impeller (101)
•
Thrust bearing end cover, outboard (ball and sleeve bearing construction only) (109A)
•
Shaft (122)
•
Radial bearing end cover, inboard (ball bearing construction only) (160) and (160A)
•
Impeller key (178)
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, 114A)
•
Sleeve bearings, two (117) (sleeve bearing construction only)
•
Impeller locknut, radial (124)
•
Throat bushing (125)
•
Impeller locknut, thrust (130)
•
Bearing locknut (136)
•
Impeller wear rings (142)
•
Casing wear rings (164)
•
Radial bearing (168) (ball bearing construction only)
