Maintain the correct hardness differential between mating wear rings to prevent galling. 4. Reassembly and Mechanical Seal Installation Install new API 682 compliant mechanical seals. Check shaft endplay and radial movement.

Note: I assume you want a practical, user-focused resource compilation and workflow for locating and using API 697 materials. Below is a structured guide you can use as a web page, README, or printable checklist.

Incorporating improvements to enhance reliability.

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.

Before any metal is measured, the pump must be safely prepared.

Pirated documents are rarely the latest revision, which can lead to dangerous engineering errors. Check shaft endplay and radial movement

Perform non-destructive testing (NDT) like dye-penetrant inspection on the impeller. 2. Rotor Balancing Clean all rotating elements thoroughly.

This standard covers the entire repair lifecycle for API 610 pump types (OH1–OH5 and BB1–BB5). 1. Field Inspection & Scope Definition Initial Discovery

Used on ferromagnetic components to detect surface and near-surface flaws.

While full official versions are sold through authorized distributors like the Accuris Standards Store GlobalSpec : Creating a definitive repair work scope for

Requirements for a final "repair document package" to chronicle all inspection results and actions taken. Applicable Pump Types

Repairing a process pump involves a sequence of precise engineering steps. Deviating from these steps shortens the mean time between failures (MTBF). 1. Pre-Disassembly Inspection
