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.
Benefits at a glance
- Clean feeding – suitable mesh sizes & designs for trouble-free material flow.
- Stable processes – negative pressure/∆p monitoring & defined cleaning/change intervals.
- System protection – prevents nozzle/valve blockage and pump wear.
- Audit-ready documentation – strainer data, cleaning & changes as PDF/CSV and QR labelled.

What suction strainers are available and what are they used for?
Suction strainers (suction filters) protect pumps and spray equipment from particles. Common versions include stainless-steel and plastic strainers in various mesh sizes, foot valves with integrated strainer, in-tank filters and pre-filters for guns/hoses. They are used in colour, clear coat, primer, resins and adhesives.
How do I select mesh size and design for my medium?
Key factors are viscosity, particle size, desired flow rate and pump type. Typical mesh sizes range from approx. 100–400 µm; finer strainers offer better protection but increase pressure drop. Ensure sufficient filter area, media-/solvent-resistant materials (e.g. stainless steel 304/316) and a suitable connection geometry.
How do I keep suction strainers process-safe and audit-proof documented?
Define and document cleaning and change intervals based on negative pressure/∆p limits or operating hours. Record strainer type, mesh size, material, batch/lot number, installation position and date. Labels/QR codes enable clear assignment; PDF/CSV exports ensure audit-proof storage.
