Description

GESTRA SZ 36A Strainers DN 40–200 | Flanged Industrial Strainer PN 10/16/25/40, ASME Class 125/150/300

Wafer-pattern strainers with exchangeable mesh screen for sandwiching between pipe flanges. Installation in any position. Thanks to the straight-through flow design there is hardly any pressure loss. For use with fluids, gases and vapors. Please ob- serve the classification according to the Pressure Equipment Directive. For fitting between pipe flanges to DIN/EN, BS and ASME. The four centering cams on the body (DN 40 – DN 100) greatly facilitate the mounting process. With broad sealing surfaces.

Design

Body with patented universal centering (DN 40 – DN 100) and drain hole.
Robust hemispherical screen.
Mesh size 1.25 mm for DN 40 – DN 100.
Mesh size 1.6 mm for DN 125 – DN 200.
Optional: fine screen, mesh size 0.25 mm.
Optional: free of silicone / free of oil & grease / pickled and passivated.
