Anping County Boli Hardware Wiremesh Products Factory, established in 1998, presents our high-performance Automatic Self-Cleaning Disc Strainer (4 inch, 304 SS, 50 micron, 220V motor). Designed for reliable and continuous filtration in demanding industrial environments, this strainer eliminates manual cleaning downtime and reduces maintenance costs. Built with premium 304 stainless steel and a robust 220V motor, it ensures consistent fluid quality for water treatment, irrigation, and process applications.

Our automatic disc strainer leverages a unique disc stack design that traps particles down to 50 microns. When differential pressure triggers the cleaning cycle, the motor rotates the discs, releasing trapped debris without interrupting flow. This self-cleaning mechanism makes it ideal for systems requiring constant operation, such as cooling water, wastewater, and agricultural irrigation.

Key Features & Technical Specifications

Material: 304 Stainless Steel (body & discs) – excellent corrosion resistance and durability.
Size: 4 inch (DN100) flanged connection – standard for medium to large pipelines.
Filtration Precision: 50 micron – captures fine sand, silt, rust, and organic particles.
Motor: 220V AC, 50/60Hz, IP54 rated – reliable and energy-efficient.
Cleaning Mechanism: Automatic self-cleaning via motor-driven disc rotation; no external water or air required.
Control: Differential pressure switch (standard) with optional timer and remote monitoring.
Max Working Pressure: 10 bar (customizable up to 16 bar upon request).
Temperature Range: -10°C to 80°C (standard); higher temperature versions available.

Parameter	Specification
Model	BOLI-DS-4-50
Filtration Area	Approx. 0.8 m²
Flow Rate (Max)	Up to 80 m³/h (depending on water quality)
Cleaning Duration	About 10–15 seconds per cycle
Power Consumption	0.37 kW (motor)
Connection	Flanged (ANSI 150 / DIN PN10 optional)

Advantages Over Traditional Strainers

No Manual Cleaning: Automated self-cleaning reduces labor and operational interruption.
Low Maintenance: Disc stack design minimizes wear; only periodic inspection of motor and seals needed.
Consistent Flow: Cleaning cycle is short (10–15 seconds) and does not require bypass, ensuring continuous filtration.
Compact Design: Compared to bag filters or multimedia filters, this strainer saves space and is easy to install.
Customizable: Available with different micron ratings (20–200 micron), motor voltage (110V/220V/380V), and materials (316 SS optional).

Frequently Asked Questions

Q: What is the working principle of this disc strainer?
A: Water enters the strainer and passes through a stack of specially designed discs. Particles larger than 50 micron are trapped on the disc surface. When the pressure difference across the discs reaches a preset value (usually 0.5 bar), the control unit activates the motor, which rotates the discs and releases the trapped debris. The cleaning cycle takes only a few seconds, and the flow is not interrupted.
Q: Can I use this strainer for seawater or corrosive fluids?
A: The standard model is made of 304 stainless steel, which is suitable for fresh water, neutral liquids, and mild environments. For seawater or high-chloride fluids, we recommend upgrading to 316 stainless steel. Please consult our sales team for material recommendations.
Q: What is the required maintenance frequency?
A: The self-cleaning mechanism reduces maintenance significantly. We recommend inspecting the disc stack and seals every 3–6 months, and lubricating the motor bearings annually. The motor is IP54 rated, but avoid prolonged exposure to heavy rain.
Q: Can I adjust the cleaning frequency?
A: Yes. The standard control box includes a differential pressure switch. You can also add a timer to initiate cleaning at set intervals. The cleaning cycle is adjustable via the control panel. Custom PLC control is available upon request.
Q: What is the maximum operating temperature?
A: The standard design can handle up to 80°C (176°F). For higher temperature applications (up to 120°C), we can use specially selected seals and motor. Please provide your specific temperature requirements.
Q: How do I install the strainer? Does it require a bypass?
A: The strainer should be installed horizontally or vertically (with flow direction from bottom to top) in a pipeline. A bypass line is not mandatory because the self-cleaning cycle does not interrupt flow. However, we recommend installing isolation valves upstream and downstream for maintenance convenience.
Q: What is the warranty and what countries do you ship to?
A: We offer a 12-month warranty against manufacturing defects. We ship from Tianjin, Qingdao, or Shanghai ports. Our main export markets include North America, South America, Europe, Southeast Asia, Africa, and Oceania. We can also arrange door-to-door delivery for some regions.
Q: Can I get a sample for testing before placing a bulk order?
A: Yes, we provide sample units at a reasonable cost. The sample price will be deducted from the first bulk order. Lead time for a sample is typically 15–20 days.
