Truncated Conical Strainers
(Series PB - RF/FF)

  Perforated Basket (PB) or truncated cone strainers are an alternative to the conical strainer. PB strainer performance is comparable to the PC strainer with the advantage of larger internal volume for retained solids; this results in lower pressure drops over time and subsequently longer allowable time between cleanouts. PB strainers contain more open area than an equivalent length cone strainer.
Standard Material: 14 ga. Perforated plate 1/8" dia. holes on 3/16" centers (40% open area, 33 holes/sq. in.)
