Dear CR4 Sirs, I have a service I'm subscribing for but has little experience on. The SERVICE DESCRIPTION reads: "The required service is to carry out a complete refurbishment of the pump rotors of the Sea Water Lift Booster Pump (SWLBP). This includes as-received inspection of the pump rotors, cleaning of the pump rotors,dimensional checks, balancing of the pump rotors (2.5g) and the submission of a final repair/refurbishment report." I am an assistant in this service, my superiors need my information, and here I am on CR4 soliciting your informed experience and advice on how to serve this description satisfacorily. Thank you sirs
