Cone Strainers / Start-up Strainers Type W-HS – Reliable System Cleaning During Commissioning
Type W-HS cone strainers are specifically used during plant commissioning to clean piping systems effectively and efficiently. As proven start-up strainers, they reliably protect downstream valves, pumps, and measuring devices from dirt particles and installation residues.
Robust design for temporary use
The W-HS startup strainers feature a high-quality stainless-steel screen insert (W-HS-S). This insert is mounted as a clamping solution between the DIN or ANSI flanges of the W-HS-G housing. This design allows for quick installation without extensive effort and is ideal for temporary use during the start-up phase.
Wide range of sizes and designs
The conical strainers are standardly available in:
- Nominal sizes from DN 50 / 2″ to DN 600 / 24″
- Various mesh sizes
- Face-to-face lengths according to EN 558-1
This allows Type W-HS cone strainers to be flexibly adapted to different plant requirements.
Special designs and accessories available on request
For specific applications, special lengths and additional accessories are available, including:
- Connections for differential pressure measurement
- Customized adaptations to process conditions
