Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export values exceeding US$5 million. Our Dome-shaped Intake Screen with 0.2mm Slot Width is engineered from premium 304 stainless steel to deliver exceptional pump protection in demanding environments. This robust strainer prevents debris entry, ensures consistent flow, and extends equipment life — all while maintaining a compact, easy-to-install design.

Key Features & Technical Specifications

Material Excellence: Made from 304 stainless steel, offering outstanding corrosion resistance, durability, and suitability for fresh water, seawater, and many chemical solutions.
Precise Filtration: 0.2mm slot width effectively blocks particles as small as 200 microns, protecting pumps from sand, sediment, and organic debris.
High Pressure Rating: Rated for 100 PSI (6.9 bar), ensuring reliable performance in moderate to high-pressure systems.
Versatile Connection: Available in NPT sizes from 1/2 inch up to 4 inches, compatible with standard pipe fittings in industrial, agricultural, and municipal applications.
Dome Shape Design: The curved surface increases screen area, reducing pressure drop and allowing higher flow rates compared to flat screens of the same diameter.
Easy Maintenance: Smooth surface and open structure minimize clogging; cleaning is simple with backwashing or manual brushing.

Frequently Asked Questions

Q: Can this screen be used for submersible pumps? A: Yes, the dome shape is ideal for submersible pump intakes. The 304 stainless steel construction resists corrosion in groundwater and most freshwater applications.
Q: What is the maximum flow rate for a 2" NPT size? A: Flow rate depends on system pressure and fluid viscosity. As a guideline, the 2" screen can handle up to approximately 80 GPM (18 m³/h) at 100 PSI with minimal pressure drop.
Q: How do I clean the screen? A: Simple backwashing or brushing with a soft brush is effective. For heavy debris, remove the screen and soak in a mild acid solution (e.g., vinegar) to dissolve mineral deposits.
Q: Is the 0.2mm slot suitable for sand filtration? A: Yes, 0.2mm (200 micron) slots effectively retain fine sand and silt particles. For finer filtration, we offer slots down to 0.1mm (100 microns).
Q: Can you provide NPT threads other than standard sizes? A: We can customize threads to BSP, NPSM, or flange connections per your request. Minimum order quantities may apply.
Q: What is the typical lead time? A: For standard sizes (1-2 inch), stock is usually available with lead time of 7-15 days. Custom sizes require 15-25 days depending on quantity.
Q: Do you have certifications like ISO? A: Our products meet industry standards for quality and performance. While we do not currently hold ISO certification, we follow strict internal QC procedures and can provide material test reports.
Q: What is the minimum order quantity? A: MOQ is 10 pieces for standard sizes, lower for samples. Large orders receive discounted pricing.
