Rotary Strainers

The Rotary Strainer is a separation device designed for continuous delivery of a strained liquid or slurry stream, free of oversize particles. With a Fluid-Quip rotary strainer installed ahead of your process equipment, you can rest assured knowing that your process is protected against contamination, and your process equipment is protected against plugging, excessive wear, or failure due to contamination. Our improved design allows for consistent operation and minimal maintenance.
