Calculate the allowable residual unbalance using ISO 1940 Grade G1.0 or G2.5 formulas. Shaft Straightening Constraints
Renew wear rings if clearances exceed 150% of the maximum design limit.
Before work begins, numerous steps are outlined to ensure a safe and smooth process, such as:
Before any mechanical work begins, the pump must be safely isolated, drained, and decontaminated. api 697 pump repair pdf free download
API 610 specifies strict guidelines for wear ring clearances based on the nominal diameter of the running surface. As a rule of thumb, standard commercial clearances are often widened slightly for high-temperature applications to prevent thermal binding. During a standard repair, if the diametrical clearance exceeds , the wear rings must be replaced or machined and sleeved. Shaft Straightness (TIR)
Use an optical flat and monochromatic light to check seal face flatness. Bearing Fit Standards

Some engineering schools or large corporations might have site-wide licenses or subscriptions to standards libraries that include API documents. If you are a student or employee, check your institution's library or internal technical resources for access.
Before hunting for a PDF, you must understand the document itself. – officially titled "Pump Repair – Reciprocating Pumps" – is published by the American Petroleum Institute. It specifies the minimum requirements for disassembly, inspection, repair, reassembly, and testing of reciprocating positive displacement pumps.
Provides "Generally Accepted" values for fits and clearances if Original Equipment Manufacturer (OEM) specs are missing. 🔍 Where to Find Technical Content API 610 specifies strict guidelines for wear ring
You aren't really looking for a "free download." You're looking for the exact tolerances for that cartridge seal. You're looking for the step-by-step alignment procedures to make sure the repair holds up against three hundred pounds of pressure and aggressive chemicals. You need the blueprint.
Visual inspection cannot detect subsurface fractures or microscopic fatigue cracks. API-compliant facilities utilize several NDT methods:
