Flowserve Vertical Immersion Sump Pump 2E4x3SP-10

Verify connections to lubrication fittings

Enter the flow rate of flushing fluid per bearing (LPM)

Enter the pressure of flushing fluid above sump pressure (kg/cm²)

Is the flushing fluid clean and from an external source?

Are rubber bearings wet during operation?

5.1 Pre-commissioning procedure

Ensure all pre-startup checks are completed

Rotate the shaft by hand to ensure all rotating parts move freely and no foreign objects are in the pump casing

Start and regulate all flush lines

Start the driver (electric motor)

Slowly open the discharge valve until desired flow is reached

Check for issues during startup

Cover the shaft threads with Teflon tape

Attach the stuffing box [4110] to the upper column [1341.1]

Set the impeller and mark the shaft at box face before seal assembly

Disassemble the pump to install and set the seal according to instructions

Install the seal according to instructions provided with the seal

Lubricate the seal rotor properly

Slip the seal [4200] onto the shaft [2100] and slide it down

Select the bearing group for lubrication

Ensure the bearing temperature is under 71°C (160°F)

Lubricate the external duplex angular contact thrust bearing [3031] through the grease fitting [3853.2]

Select the recommended grease used

Ensure not to overfill the motor or pump thrust bearings with grease

Confirm the maximum temperature of the rolling element bearing does not exceed 105°C (220°F)

Inspect impeller for excessive wear and etching due to corrosion

Check pump shaft for straightness

Inspect the surface of the shaft in the bearing areas for smoothness

Check ends of shaft for burrs and cleanliness of shaft threads

Inspect the casing thoroughly, removing all burrs and foreign matter

Check all other parts for burrs, wear, damage or corrosion

Use a dial indicator to check the straightness of the shaft extension of the driver

Inspect inside of bearings in the adapter and intermediate bearing holder(s)
