WATER STRAINER Model 254-XXX
Installation and Maintenance
The SHURflo Extreme Series strainer prevents damage to the pump by trapping small particles and
debris. This strainer uses a #40 mesh screen to trap foreign debris and particulates larger than .02
in.[.3mm]. The Extreme Series strainer is designed for installation either directly to a SHURflo
quick-connect port pump (inlet side) or in-line before the pump. It can be installed in any
convenient, easy to inspect location between the water supply (tank) and the pump. The strainers
transparent material allows for quick visual inspection for determining if the stainless steel screen
should be cleaned. When correctly installed, no tools are required to open; hand disassembly is
quick and simple due to the bowl screw feature.
