Shanghai Zhibang Valve Manufacture Co., Ltd., a professional manufacturer established in 2016 with ISO9001 certification, specializes in producing high-performance marine fluid control components. Our CB/T497-94 Marine Suction Coarse Water Filter is engineered to provide reliable protection for critical marine pumping systems. This robust filter ensures the longevity of pumps and associated equipment by effectively removing coarse debris from suction water lines, a vital function for operational safety and efficiency in maritime applications.
Core Product Features & Technical Advantages:
- Durable Material Construction: The filter body is made from high-grade cast iron, offering excellent corrosion resistance and structural strength against marine environments. The internal basket is constructed from stainless steel, ensuring long-term durability and preventing rust contamination.
- Standardized Design: Manufactured in strict compliance with the Chinese marine standard CB/T497-94, guaranteeing dimensional accuracy, performance reliability, and interchangeability for standardized marine systems.
- Effective Coarse Filtration: Designed specifically for the suction side of pipelines, it captures large particulate matter such as seaweed, plastic fragments, wood, and other coarse debris before it enters pumps, preventing clogging, impeller damage, and cavitation.
- Easy Maintenance: The design typically allows for relatively straightforward access to the stainless steel basket for periodic cleaning or inspection without requiring complex disassembly of the entire pipeline section.
- Flanged Connections: Standard flanged ends facilitate secure and leak-proof installation into the marine piping system, compatible with common marine pipeline flange standards.
- Application Versatility: Suitable for various seawater intake applications on vessels, including ballast water systems, cooling water intake, firefighting water supply suction, and general service water suction lines.

Frequently Asked Questions (FAQ):
Q1: What is the main purpose of this marine suction coarse water filter? A: Its primary purpose is to act as a strainer on the suction side of a marine water pipeline. It filters out coarse solids and debris (like seaweed, plastic, wood chips) from the intake water before it reaches and potentially damages pumps, valves, or other sensitive equipment.
Q2: Why is the body made of cast iron and the basket of stainless steel? A: Cast iron provides a robust, cost-effective, and corrosion-resistant body suitable for the marine environment's structural demands. The stainless steel basket offers superior resistance to corrosion in direct contact with water and debris, ensuring the filtering element itself remains durable and functional.
Q3: Does compliance with CB/T497-94 mean it's only for Chinese vessels? A: No. CB/T497-94 is a Chinese national standard for marine strainers. Many international shipbuilders and repair yards recognize or utilize components built to various national standards. It signifies a standardized design, dimensions, and performance criteria, making it suitable for global applications where such specifications are accepted or required.
Q4: How often does the filter basket need cleaning? A: The cleaning interval depends heavily on the water quality and debris load at the intake location. It is recommended to inspect and clean the basket during regular marine system maintenance schedules. The design facilitates access for this routine maintenance.
Q5: Can this filter handle high flow rates? A: The filter is designed for marine suction line applications. Specific flow rate capacity depends on the nominal size (DN) of the filter. Please consult with us for your required flow rate and pipe size to select the appropriate model.
Q6: Are different sizes available? A: Yes. Marine suction filters are typically produced in a range of nominal diameters (DN) to match different pipeline sizes. The exact available sizes for the CB/T497-94 model can be provided upon request.
Q7: What are the typical pressure ratings for this filter? A: Pressure ratings are associated with the specific model and size. Cast iron construction can accommodate typical marine suction line pressures. Detailed pressure rating information is available for each size option.
Q8: Do you provide installation guidance or drawings? A: As a manufacturer, we can provide general installation guidelines and dimensional drawings for the selected filter size to assist with integration into your marine piping system.
