Is Lateral analysis and rotor dynamic analysis required for VS6 pumps

Is Lateral analysis and rotor dynamic analysis required for VS6 pumps

Is Lateral analysis and rotor dynamic analysis required for VS6 pumps

(OP)
Hi,

I have been asked by the client to modify the existing VS-6 API 610 pumps for the new process conditions.

The existing pump had 9 stages and in the new modified pump 4 impellers will be kept at exiting trim, add a stage and 5 impellers will be replaced.

Please let me know if a lateral and rotor dynamic analysis is required for these pumps.

flow: 120 m3/hr
head: 594 m

THANK YOU

RE: Is Lateral analysis and rotor dynamic analysis required for VS6 pumps

No. The only thing I would do is confirm the MAWP of the pump with the increased pressure, and confirm the speed torque curve and pump thrust will be ok with existing motor.
