PM Checklist

Definition

We have preventative maintenance (PM) checklists for 516 common asset classes. Utilize our PM inspection registry to improve your PM program. See an example PM Checklist for a Centrifugal Pump below or download your copy today.

Frequency

Tasks

Daily

Check pump for noisy bearings and cavitation.

Daily

Check bearing oil for water and discoloration.

Daily

Feel all bearings for temperature.

Daily

Inspect bearings and oil rings through filling ports. Wipe bearing covers clean.

Daily

Check oil leaks at the gaskets.

Daily

Self flush pumps - Hand check the flush line temperature to determine flow through the line. External flush pumps - Determine if flow indicator and needle valve adjustment are functioning properly.

Daily

Determine if the mechanical seal conditions are normal.

Daily

Check any water cooling for effective operation. Hand test differential across coolers, jackets and exchangers. Disassemble and clean as required.

Daily

Check the operability of the heat tracing.

Daily

Check for leaks at pressure casing and gaskets. Determine if steam traps are operating properly - no continuous blow & water in casing or drain.

….

Monthly

Clean oiler bulbs and level windows as required.

Monthly

Clean out debris from bearing brackets. Drain hole must be open.

Monthly

Change oil in hydraulic governors.

Monthly

Check for proper oil level & leaks at hydraulic governor. Check for oil leaks at lines, fittings & power piston.

….

Half-Yearly

Machines not running - Standby service: Overfill bearing housing to bottom of the shaft and rotate several turns by hand to coat the shaft and the bearing with oil.

Half-Yearly

Apply a light coat of rust preventive product to expose machined surfaces to prevent rust and corrosion.

Half-Yearly

Clean & oil governor linkage & valve stems.

Half-Yearly

Exercise overspeed trip & valve steam linkage on turbines not running.

….

Yearly

Thoroughly inspect disc coupling for signs of wear & cracks in laminations. Tighten bolts.

Yearly

Using a dial indicator, check the coupling alignment with the equipment coupled. Use special coupling indicator clamps where possible. Ensure that thermal growth allowance is correct.

Yearly

Using an indicator clamped on the coupling, depress and lift on each coupling and note the dial indicator change. Determine if the deflection is normal for this machine. Refer to OEM manual.

Yearly

Using an indicator, check axial float of the pump & the driver shaft in similar manner.

Yearly

Remove turbine sentinel valve. Shop test & adjust to proper setting.

Yearly

Inspect trip and throttle valve stems and their linkages for wear. Check over-speed mechanism for wear. (Turbine must be down).

Yearly

Remove mechanical the governor cover & inspect flyball seat, spring, bearing & plunger for wear.
