Flowserve Pump 16-MFC-18

Pumps fitted with mechanical seal

Ensure no adjustment is made to the mechanical seal

Run in the pump mechanical seal using clean liquid before pumping dirty liquids

Start external flush or quench before running the pump

Allow external flush or quench to flow after the pump has stopped

Ensure the mechanical seal is never run dry

Verify no adjustment is possible for the mechanical seal

Ensure the correct materials are used

Remove old packing and seal cage halves, then clean the stuffing box

Verify the packing is of correct type and size

Measure the stuffing box to determine the proper length of packing

Cut packing slightly shorter than measured length

Insert each ring of packing separately and seat it firmly

Stagger the rings so that successive joints are 90° to 180° angles apart

4.8 Final shaft alignment check

Rotate the shaft several times by hand to ensure there is no binding and all parts are free

Recheck the coupling alignment to ensure no pipe strain

6.1.2 Periodic inspection (semi-annual)

Check the coupling for correct alignment

Inspect for worn driving elements

4.5.4 Alignment criteria for MFC pumps

Check Total Indicator Reading (TIR) for Woods type coupling

Check Total Indicator Reading (TIR) for all metal flexible type coupling

Periodic inspection (semi-annual)

Ensure the maximum time between cleaning and lubrication change is one year.

Determine if the environment and conditions require shorter frequency of maintenance.

Complete cleaning during a major overhaul

Use a brush and wash out the housing with hot oil or non-toxic solvent.

Flush the housing with light mineral oil to prevent rust.

Remove solid particles with a brush dipped in hot oil while gently spinning the bearing.

Is there badly oxidized grease present?

Normal Vibration Levels, Alarm and Trip

Measure the vibration velocity of the pump motor (unfiltered, r.m.s.)

Is the vibration velocity within the normal range for the motor power?

Calculate and record the alarm value (N × 1.25)

Calculate and record the trip value (N × 2.0)

Pump and Motor Bearings Temperature

Record the bearing temperature (t)

Record the ambient temperature (ta)

Estimate and record the likely maximum ambient temperature (tb)
