20mm Water Pump Prefilter with Coarse Stainless Screen for Marine Use - RWB1426

20mm Water Pump Prefilter with Coarse Stainless Screen. This water-pump prefilter is intended to help protect electric diaphragm pumps from debris in the water supply. It has an integral mounting bracket, a transparent housing and a coarse stainless steel mesh screen. Hose-barb connections suit the specified hose size. The body is 90mm high and measures 100mm across including the barbs, giving useful dimensions for checking the available mounting space. The transparent housing allows the screen area to be inspected before deciding whether cleaning is needed.

Choosing and using this product

Check the pump's installation instructions and confirm that the chosen hose size and strainer arrangement suit the inlet system. Mount the housing where it can be inspected and opened for cleaning, allowing clearance beyond the basic body dimensions. Use the integral bracket to support the filter rather than leaving it suspended from the hoses. Route the inlet and outlet hoses without tight bends or side loads, and choose clamps for the installed hose diameter. A prefilter helps manage debris but does not replace any required drinking-water treatment or the pump's other installation requirements. After fitting, operate the pump and check the housing, hose joints and water flow. Inspect the screen after initial commissioning if the water line has been disturbed or replaced. Check the service clearance with the surrounding equipment in place. Before opening the filter, isolate the pump and relieve any pressure safely. Clean the screen and sealing surfaces, then reassemble and test for leaks. Keep the transparent housing visible and do not use the space around it for storage that blocks service access. Recheck the bracket and connections during routine pump maintenance.
