API standards dictate specific diametrical clearances based on the pumping temperature and material galling characteristics. Component Material Temperature Range Minimum Diametrical Clearance Cast Iron / Bronze Under 200°C OEM Standard Stainless Steel (Galling) Over 200°C OEM Standard + 0.125 mm Non-Galling Composites Reduced Clearance Allowed The Risk of Excessive Clearance When wear ring clearances double due to erosion: Volumetric efficiency drops by up to 5%. Power consumption increases significantly.

Components are cleaned (usually via blast cleaning) to allow for NDT (Non-Destructive Testing) such as dye penetrant or magnetic particle inspection to detect cracks.

Every API-level pump overhaul must end with a comprehensive QA/QC document packet. Ensure your repair facility provides:

For minor journal wear, qualified facilities may use automated weld overlay (cladding) followed by finish machining and grinding to restore original dimensions. Wear Ring Replacement and Clearances Components are cleaned (usually via blast cleaning) to

If your "free download" lacks these, it is likely a generic maintenance sheet, not a true API 697 document.

Proof that replacement wear rings or shafts match the original API material class (e.g., S-6, C-6, A-8). Wear Ring Replacement and Clearances If your "free

The standard covers the entire pump repair lifecycle, including:

Precision measurement dictates the success of a pump rebuild. Technicians use calibrated micrometers and coordinate measuring machines (CMM) to check:

A key technical detail is that after disconnecting piping, the maximum permitted shaft movement in any direction is 0.002 inches. This check ensures hidden pipe strain isn't forcing the pump out of alignment.
