A European engineering company was seeking a reliable and cost-effective alternative to a well-known German automatic back-flushing filter used in its industrial water treatment system.
Their previous supplier offered stable performance but at a very high price and long delivery time. The client wanted a replacement solution with equivalent quality, full documentation, and faster delivery for a cooling water filtration project.
Filtration medium: Process cooling water
Flow rate: Up to 150 m³/h per unit
Operating pressure: 6–10 bar
Filtration accuracy: 300 microns
Material: Stainless steel 304 / 316L
Flange standard: DIN PN16
Documentation required: Hydrostatic test report, welding qualification, strength calculation, and material certificates
After detailed technical comparison, SFFILTECH proposed two customized automatic back-flushing filter models (BCM500 and BCM300), designed to match the client’s existing installation and piping configuration.
Both filters were equipped with:
Automatic backwashing function triggered by differential pressure sensors
PLC-based control system for fully automatic operation
Heavy-duty stainless steel housing fabricated according to EN and ASME standards
Complete quality documentation package, including:
Hydrostatic test report
Strength and pressure calculation
WPS/WPQR and welder certificates
EN 10204 3.1 material certificates
Final product inspection record
Cost Reduction: Saved not only 50% compared to the previous European brand
Shorter Lead Time: From 14–16 weeks down to 5–6 weeks
Reliable Operation: Stable automatic backwash cycle, no manual cleaning needed
Compliance: Accepted by EU engineering consultants after reviewing the document package
Customer Satisfaction: The user reported smooth operation and no clogging issues during the first 6 months of service
This project demonstrates how SFFILTECH’s Chinese-engineered automatic filter housing can successfully replace expensive European brands in demanding industrial applications — delivering the same performance, faster delivery, and much higher cost-efficiency.
SFFILTECH continues to support global partners in industrial water, oil, and process filtration projects, providing OEM-level engineering, documentation, and long-term service support.
