Product Data
Theoretical flow rate (for 100 mm : 10–82 m³/h. Actual flow depends on liquid viscosity, filtration accuracy, and turbidity.
Operating temperature: 160°C (achievable with high-temperature sealing components).
Operating pressure: 1.0 MPa standard; higher pressures available on request.
External-scraper filter equipped with V‑slot (wedge‑wire) precision metal screen elements:
Filtration range: 50–500 μm.
Slot width tolerance: ≤5 μm.
Screen material: 316L stainless steel for corrosion resistance.
V‑shaped slot geometry prevents particle jamming and maintains stable flow over time.
Smooth inner and outer surfaces.
Structural rigidity prevents slot deformation under differential pressure.
Withstands high forward and reverse pressure surges.
Product Advantages
Fully automatic operation – The rotating scraper removes accumulated solids without manual intervention. Continuous online filtration (24/7) eliminates cartridge replacement and disposable filter media, reducing both consumable costs and waste disposal expenses.
Scraper design – Metal blade scrapers wipe the screen surface; they remove debris without crushing or forcing particles through the screen, maintaining filtration efficiency.
V‑slot (wedge‑wire) filter elements – Precision‑manufactured with accurate slot tolerances and smooth surfaces, they allow easy cleaning, resist clogging, maintain low pressure drop, and provide stable flow rates over extended service life. The rigid structure withstands pressure differentials without deformation.
Closed‑loop, safe operation – The fully enclosed housing prevents leakage of hazardous fluids, ensuring process safety. Discharged waste has high solids concentration and can be recycled, minimising loss of valuable product.
Drive reliability – Equipped with internationally recognised brand gear motors for dependable long‑term service.
Flexible configuration options – Available with:
- Jacket heating for thermal oil (2 kg/cm²) or hot water (4 kg/cm²) to maintain fluid temperature and pumpability.
- Explosion‑proof design for flammable liquids.
- Food‑grade surface polishing for easier cleaning.
- Top‑cover lifting arm for simplified maintenance access.
- Modular units in series for higher flow capacities.
- Mobile filter carts for shared use across multiple stations, reducing capital investment.

Product Application
Note: Standard filter medium is V-slot wedge-wire screen; sintered metal, PP and multi-layer PTFE media are optional for different working conditions. Standard scraper is metal blade; PTFE scraper is an exclusive option for pharmaceutical sterile process. Max structural temperature reaches 160°C, while ≤90°C is the limit for standard pharmaceutical & fermentation filter media.
