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

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.
