As a specialized manufacturer with ISO9001-certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. provides reliable filtration solutions for the global maritime industry. Our CB/T497-94 Marine Water Filter is engineered specifically for the critical role of protecting main engine auxiliary cooling systems from particulate contamination. By ensuring clean cooling water, this filter directly contributes to reduced maintenance costs, enhanced operational reliability, and extended service life for vital engine components, making it a fundamental investment for vessel efficiency and safety.

This marine water filter is designed to meet the rigorous demands of shipboard environments. Its robust construction and precise filtration capability safeguard sensitive heat exchangers, pumps, and piping within the cooling circuit. Key features and technical specifications include:

Compliance with CB/T497-94: Manufactured in strict accordance with this Chinese shipbuilding standard, ensuring compatibility and reliability for a wide range of marine applications.
High-Capacity Filtration: The large-surface-area stainless steel mesh basket provides efficient solids separation with minimal pressure drop, maintaining optimal coolant flow.
Durable Construction: The main body is typically crafted from corrosion-resistant materials like cast iron with epoxy coating or stainless steel, suitable for seawater and freshwater service.
Easy Maintenance: Designed for straightforward access; the filter basket can be easily removed, inspected, and cleaned without requiring complex disassembly of the piping system.
Versatile Configuration: Available in various nominal diameters (DN) to match different flow rate requirements of auxiliary cooling systems.
Optional Instrumentation: Can be equipped with pressure gauges or differential pressure indicators to provide visual alerts for when the basket requires cleaning.

The technical advantages translate into tangible benefits for ship operators and engineers:

Feature	Benefit to Customer
Standardized Design (CB/T497-94)	Ensures interchangeability, simplifies spare parts procurement, and guarantees performance meets industry expectations.
Robust Stainless Steel Basket	Provides long service life, resists corrosion from coolants, and can be cleaned and reused multiple times.
Minimized Pressure Drop	Helps maintain the designed efficiency of the cooling water pump, reducing energy consumption.
Easy Access for Cleaning	Reduces downtime for maintenance, lowers labor costs, and promotes proactive system care.
Configurable Ports & Options	Allows customization to fit specific space constraints and operational monitoring needs on board.

Typical technical parameters for selection are as follows (specific values are customizable based on project requirements):

Parameter	Common Range / Specification
Nominal Diameter (DN)	50, 80, 100, 150, 200, 250, 300 mm
Maximum Working Pressure	1.0 MPa, 1.6 MPa, or as requested
Suitable Medium	Sea Water, Fresh Water, Coolant
Filtration Mesh Size	Customizable (e.g., 0.5mm, Building upon the trust established through our ISO9001 certification and a successful track record of exporting to diverse markets including North America, Southeast Asia, Europe, and Africa, Shanghai Zhibang stands behind the quality and performance of every CB/T497-94 filter we produce. Our annual export value reflects the consistent satisfaction of our global clientele. We offer flexible shipment options from major Chinese ports to ensure timely delivery. Choosing our marine water filter means selecting a component built for durability and backed by a manufacturer committed to maritime industry standards. Frequently Asked Questions (FAQ) Q: Is this filter suitable for both seawater and freshwater cooling systems? A: Yes, provided the appropriate body and basket materials are selected. We offer material options like coated cast iron or stainless steel to handle the corrosiveness of seawater effectively. Q: How often does the filter basket need to be cleaned? A: The cleaning interval depends entirely on the level of particulate in the cooling water. We recommend regular inspection. Many models can be equipped with a differential pressure gauge; a significant pressure increase across the filter indicates it's time for cleaning. Q: Can you provide filters with connection standards other than those in CB/T497-94? A: While we manufacture to the CB/T497-94 standard for dimensions and performance, we can often accommodate specific flange standards or threading (e.g., ANSI, JIS) upon request. Please inquire with your requirements. Q: What is the typical lead time for an order? A: Lead time varies based on order quantity, specifications, and current production schedule. Standard configurations typically have shorter lead times. We provide accurate timelines upon receipt of your detailed inquiry. Q: Do you offer a complete package with spare baskets or gaskets? A: Yes, we strongly recommend ordering spare filter baskets and seal kits as part of your initial purchase to minimize future downtime. These are available and can be included in your order. Q: What is the main difference between this auxiliary cooling water filter and a main engine lube oil filter? A: They are designed for completely different media. This filter is for water-based coolants, handling larger volumes and typically larger particles. Lube oil filters are for viscous oil, require finer filtration, and are built to different pressure and material standards. Q: Is the filter designed for automatic backwashing, or is it manual cleaning only? A: The standard CB/T497-94 design is for manual cleaning. The unit is opened, the basket is removed, cleaned, and reinstalled. We do not typically offer automated backwashing on this specific model.
