2026 CIP strainer failure

Failed unit
4-in Spears YS33P20-040 (plastic basket/screen)
Replacement ordered
Spears YS23S30-040 — 4-in flanged PVC, 316 SS #30 mesh screen, EPDM O-ring
Replacement rating
90 psi at 73 °F; max 140 °F (60 °C)
CIP pump discharge
240 kPa
CIP temperature (max)
38 °C
Lesson
Nameplate pressure/temperature alone does not define the operating envelope; differential pressure across a plugged strainer can be the governing load. Adding upstream/downstream gauges or a DP transmitter is warranted.

Integrity testing

Automated, built into Pall system

2020 finding — PIT-1021 (filtrate pressure transmitter used in IT measurement)
Debris accumulation affecting IT pressure readings. Operator response: reportedly bled ~weekly.
Test depends on
  • clean pressure sensing
  • correct IT regulator pressure
  • leak-free module connections
  • reliable valve seating
  • proper instrument calibration
