THE PROBLEM

Recurring pump wear and mechanical seal failures

Pumps that keep eating seals, impellers or stators are almost always signalling something upstream — NPSH, misalignment, wrong technology for the fluid, or wrong elastomer.

YOU MIGHT BE SEEING

Symptoms

  • Mechanical seals failing far short of expected life
  • Impellers or wear rings wearing rapidly on abrasive service
  • PC pump stators delaminating or eating themselves within weeks
  • High vibration, bearing failures or coupling issues on centrifugal pumps
PARAGON'S APPROACH

How we solve it

1

NPSH calculation against actual suction conditions, not design assumptions.

2

Pump technology audit — centrifugal vs PC vs AODD — matched to fluid and duty.

3

Mechanical seal arrangement (API 682 Plans) sized to abrasion, temperature and hazard.

4

PC pump elastomer selection matched to fluid chemistry and temperature.

FIELD INSIGHT

If a centrifugal pump keeps eating seals, the answer is almost never a better seal — it is NPSH or misalignment. If a PC pump keeps eating stators, it is elastomer or dry-running. Fix the root cause, not the wear part.
