Practical engineering articles on selecting, installing and troubleshooting mechanical seals for pumps, mixers and compressors.
Side-by-side comparison of API Plan 32 (external flush) and Plan 53 (pressurized barrier) for mechanical seals — costs, applications, piping, and when to choose each.
Step-by-step selection guide for slurry pump mechanical seals: face materials, flush plans, single vs double, and OEM cross-references for mining, FGD and dredging service.
Diagnose mechanical seal failures fast: heat checking, blistering, chipped faces, dry-run damage, elastomer failure and installation errors — with fixes for each.
Elastomer bellows seals replace springs and dynamic O-rings with a flexible rubber bellows. Learn when they win, their limits, and OEM cross-references.
Dry gas seals and wet oil seals both seal centrifugal compressors. Compare leakage, safety, cost and the API 692 standard to pick the right compressor seal.
Step-by-step guide to safely replacing a mechanical seal on a centrifugal pump — including preparation, disassembly, installation and startup checks.
Cartridge seals ship pre-assembled; component seals ship as loose parts. Compare cost, installation time, safety and repair speed to pick the right one.
Every major mechanical seal type explained — pusher, non-pusher, cartridge, component, single, double, dry gas and more. Includes selection guide and cross-references.
Step-by-step explanation of how a mechanical seal works — the sealing faces, fluid film, spring load and secondary seals that stop leakage in pumps and mixers.
Learn what a mechanical seal is, how it works, the main types, and why it matters for pumps, mixers, compressors and other rotating equipment.
