Flowserve Pump MK3 HSI 2×1-6

Measure the current process temperature

Select the appropriate impeller clearance based on temperature

Install a new impeller gasket [4590] if the impeller has been removed

Rotate the bearing carrier [3240] to obtain the proper clearance

Turn the bearing carrier clockwise until the impeller comes into light rubbing contact with the suction cover

Rotate the shaft to accurately determine the zero setting

Ensure visible leakage and concentric alignment of the gland follower

Is there leakage from the packing gland when starting the pump?

Is the packing too loose causing air to suck in?

Allow leakage to flow freely after the pump is primed

Gradually and evenly tighten packing gland nuts until leakage is reduced to a trickle

Is the leakage reduced to a trickle without shutting off completely?

Enter the pressure introduced into tap 5 for packing lubrication (kPa)

Enter the flow rate of drops per minute for clean fluid

6.1 Maintenance schedule / 4.8 Final shaft alignment check

Check coupling alignment and re-align if necessary.

Operate the pump for at least an hour or until it reaches final operating temperature.

Shut the pump down and recheck alignment while the pump is hot.

Did piping thermal expansion change the alignment?

Enter the parallel misalignment measurement (mm).

Enter the angular misalignment measurement (mm/mm).

Is the parallel misalignment within 0.05 mm (0.002 in.)?

Ensure dirt and dust are removed from critical areas

Are regular checks being made in dirty or dusty environments?

Remove dirt from areas around close clearances, bearing housings, and motors in dirty or dusty environments

Are there any oil and grease leaks making the ground slippery?

Clean the ground before starting maintenance

Clean the exterior of the machine before starting maintenance

Clean the ground after finishing maintenance

Enter the current bearing lubricant level

Enter the remaining hours before a lubricant change is required

Is the oil level within the circumference of the center hole of the sight glass?

Is oil visible in the constant level oiler bottle at all times?

Check and fill the oil level when the pump is not operating
