Robust Filtration Solution for Critical Industrial Processes
The STK Flange-Type Cartridge Filter Housing series is built to withstand the rigors of heavy industrial operations. Unlike quick-release clamp closures designed for hygiene, the bolted flange connection offers superior structural integrity and sealing performance. It is the preferred choice for applications involving high pressures, hazardous fluids, extreme temperatures, or significant mechanical vibration.
Why Choose STARK Industrial Flange Housings?
1. Secure, High-Pressure Sealing Standard
Featuring standard **ANSI 150#/300# or DIN PN10/16/25 flange connections** on inlet/outlet ports, this housing ensures seamless integration into industrial piping systems. The main body closure utilizes a heavy-duty bolted flange design, providing a positive, robust seal capable of handling higher operating pressures (standard up to 1.6 MPa, with custom high-pressure ratings available) securely.
2. Heavy-Duty Construction for Durability
Manufactured from thick-walled **SUS304 or SUS316L stainless steel** (with optional Duplex Stainless Steel for extreme saline environments), our housings offer excellent corrosion resistance and mechanical strength. They are designed to meet or exceed industrial standards (like ASME code stamps upon request) for safety and longevity.
3. High-Flow, Multi-Round Capacity
Engineered for large-scale operations, these vessels are available in extensive multi-cartridge configurations (ranging from 3 rounds up to 150+ rounds). The internal flow path is optimized via CFD simulation to ensure uniform fluid distribution across all filter elements, maximizing filtration efficiency and cartridge life under high flow conditions.
4. Ergonomic Maintenance for Large Vessels (Davit Arm)
As shown in the product image, for larger multi-round housings where the top flange cover is heavy, we incorporate a standard **mechanical davit arm or hydraulic lid lifter**. This safety feature allows a single operator to easily lift and swing the cover aside for cartridge replacement, significantly improving maintenance safety and efficiency.
