Some possibilities are: VFD to control pump RPM Impeller trim to reduce head at same RPM Pressure reducing valve. The pump affinity laws will show you how RPM or diameter reduction will change your pressure and flow from the original. https://en.wikipedia.org/wiki/Affinity_laws

Do you have access to any of the purchasing and quality information that might go along with the drawing to get the parts? This could be PO's, supplier drawings, materials test cert's, heat treatment cert's, etc. You might at least be able to revise the drawing to reflect the present status of...
