What Is a Witches Hat Strainer? | Cone Strainer Manufacturer – YUBO Filter

In industrial filtration systems, especially in pump suction lines, I often see cone-shaped elements referred to as “witches hat strainers.”

For anyone unfamiliar, a witches hat strainer (also called a cone strainer) is a conical stainless steel filter installed directly inside a pipeline. It’s typically used as a temporary or compact solution to protect downstream equipment from debris during startup or maintenance operations.

Why engineers choose them:

Lower pressure drop compared to flat screens

Compact installation inside flanges

Good debris distribution due to angled geometry

Available in mesh, perforated plate, or wedge wire

They're commonly used in:

• Water treatment systems

• Chemical processing lines

• Pump protection

• Resin retention setups

Curious how others approach pre-filtration in tight pipeline layouts — do you prefer cone strainers, basket strainers, or temporary spool strainers?
