Hey, will this strainer keep my hydraulic pump from suckin' up too much junk?

This strainer is designed to protect hydraulic pumps from larger solid contaminants in submerged applications.

strainer says up to 16.9 GPM, is that a hard cutoff or just a recommended max?
Answer by: Customer Support on Jun 10, 2025, 8:26 AM
Rated flow on suction strainers like this one is the recommended operating ceiling, not a point where it immediately fails. Running consistently at or near that limit puts more demand on the screen and can starve the pump if the element starts loading up with debris. For a hydraulic pump pulling right around that range, this strainer fits fine. If your system regularly peaks above 16.9 GPM, stepping up to a higher-rated unit would be the smarter call.
