Product details
Slot options
Slot options include 0.1, 0.2, 0.4, 0.5 and 1.0 mm. Outside diameters of 50–600 mm and screen lengths of 100–3000 mm are combined with profile widths of 1.0, 1.5 or 2.0 mm.
Materials and connections
Choose 304, 304L, 316, 316L, duplex 2205 or super duplex 2507. Flanges, bolt patterns, gaskets, hinges and quick-opening hardware are manufactured to the mating equipment and service access.
Finishing and inspection
We configure support rods and reinforcing rings for inside-out or outside-in flow, operating differential pressure and backwashing. Inspection covers slot width, dimensions, flange fit, welds, cap operation and specified material records.
Integration with the filter assembly
The bolted mounting flange and quick-open cap perform different jobs. The flange locates the cartridge in the equipment; the cap provides service access at the element end. Their sealing faces, gaskets and fastening hardware are listed separately. The bill of materials identifies profile wire, support rods, reinforcing rings, flange, cap and wetted seal; 304/316L and duplex 2205/2507 selections are assigned to each metal component. Installation leaves clearance for both cartridge withdrawal and cap movement, and inspection checks the cap’s closed engagement as well as the screen slots.

Applications
Water-treatment intake screens
A slotted, removable screen for equipment intake or pre-screening. Select slot, wetted alloy and support arrangement for solids loading and water chemistry.
Process-liquid protection
A flanged cartridge can retain coarse process debris ahead of downstream equipment. Confirm hydraulic duty, access space and whether the screen is cleaned in place or removed.
Drawing-based replacement cartridges
Choose 304, 304L, 316, 316L, duplex 2205 or super duplex 2507. Flanges, bolt patterns, gaskets, hinges and quick-opening hardware are manufactured to the mating equipment and service access.
Selection guide
Include these details when discussing your requirements.
- Housing and flange drawing
- Send cartridge OD and installed length plus flange OD, bore, thickness, bolt circle, hole size, face and gasket details.
- End-cap access
- Show the closure, latch or fastener layout, seal location, opening direction and clearance available for removal and cleaning.
- Slot and solids
- State nominal slot width, particle or debris type, permitted carryover and whether a measured retention test is needed.
- Flow and load
- Give normal/reverse flow direction, flow rate, normal and maximum differential pressure and any backwash cycle.
- Materials and environment
- Identify process fluid, chlorides or chemicals, operating/cleaning temperature, required alloy and any material certificates.
- Order and inspection
- Provide quantity, sample or first-article requirement, critical tolerances and any specified pressure, flow or dimensional acceptance test.
Frequently asked questions
What dimensions define the mounting flange?
Provide flange OD, bore, thickness, bolt circle, hole number and diameter, sealing face and gasket seat. Include access space for the removable cap.
How is the working face selected?
Position the narrow slot entrance on the incoming-flow side. The slot widens behind the working surface; support rods and reinforcement are arranged for the normal flow and backwash loads.
