Suction strainers

Suction strainers

With the right suction strainers (suction filters), you protect pumps, hoses and nozzles against particles, fibres and gel particles – for stable and reproducible painting & coating processes. Our range includes stainless-steel and plastic strainers, foot valves with strainer, in-tank filters and pre-filters for guns/hoses. We advise on mesh sizes (e.g. 100–400 µm), flow rate, viscosity, media/solvent resistance and documentation – for consistent surface quality.

Use & benefits

Whether automotive, industry, plastics, wood or body shop & paint – correctly sized suction strainers reduce nozzle blockages, pressure fluctuations and downtime, protect pumping units and stabilise coating quality and approvals. With suitable mesh sizes, sufficient filter area and defined negative pressure/∆p limits, you keep quality and energy consumption in balance.

Tasks & set configuration

We configure suction strainers, foot valves with strainer, in-tank filters and pre-filters according to the medium, pump type (e.g. piston, diaphragm or gear pump), throughput and target quality. Mesh sizes, materials (e.g. stainless steel 304/316, PA), cleaning cycles, change labelling and limits (negative pressure/∆p) are defined; cleaning, replacement and disposal are documented via PDF/CSV export and QR labels.

Product areas & integration

The range includes stainless-steel suction strainers (robust, solvent-resistant), plastic strainers (weight-/ cost-efficient), foot valves with integrated strainer (prevent backflow) as well as in-tank filters and pre-filters for guns/hoses. All solutions are designed for pressure loss, flow rate and process safety – with clean integration into quality workflows.

For complete workstations we define strainer sets with coordinated mesh size, sufficient filter area, negative pressure monitoring and change guidelines. We consolidate bills of material, define minimum stock levels and integrate supply into audit processes – for stable quality and reliable documentation along the value chain.
