scope:

This recommended practice (RP) covers the minimum recommendations for the inspection and repair of API 610 pumps types OH1 through OH5 and BB1 through BB5. Refer to Annex A for figures and description of pump types.

This document covers the entire process of field inspection, modifications, inspection, upgrades, repair and/or new component manufacturer, reassembly of the pump casing and rotor in the shop, and the reinstallation and start-up of the pump in the field.

Pumps in hydrofluoric acid service may require inspection and repair methods that are beyond the scope of this RP.

Each phase of inspection will determine a work scope. The work scope will become more definitive as the inspection process progresses.
