Product details

In industrial operations, even the smallest particle of contamination in hydraulic oil can lead to catastrophic failures—costing businesses thousands in repairs and unplanned downtime. This is where the DF Series Filters step in: a purpose-built filtration solution designed to eliminate such risks by maintaining exceptional oil cleanliness, even in the most demanding high-pressure, high-flow hydraulic environments. Unlike generic filters that struggle to balance performance and durability, the DF Series combines advanced filtration technology, rugged construction, and flexible design to become an indispensable component for industries relying on hydraulic system reliability.

1. Engineered for High-Pressure, High-Flow Challenges

The DF Series is not just a filter—it’s a precision tool optimized for pressurized hydraulic circuits where performance cannot be compromised. With a maximum working pressure of 420 bar and flow rate capabilities spanning 60 to 1,200 L/min (model-dependent), it outperforms standard filters in scenarios where hydraulic systems operate under intense load. For example, in heavy construction equipment or large-scale manufacturing machinery, the series effectively traps harmful contaminants—such as metal debris from worn components, dust from outdoor environments, or sludge from oil degradation—that would otherwise cause valve sticking, pump inefficiency, or permanent seal damage. Its ability to integrate into existing systems without requiring major modifications further enhances its practicality for retrofits or new installations.

2. Cutting-Edge Features That Deliver Unmatched Performance

① Precision Filtration Media for Maximum Contaminant Capture

At the heart of the DF Series is Shengda‘s exclusive glass fiber or synthetic filtration media, engineered to achieve absolute filtration ratings from 3 μm to 20 μm. This level of precision means the filter captures nearly 100% of particles above its rated size—far exceeding the capabilities of conventional filters that often allow micro-contaminants to pass through. Independent third-party testing confirms that the DF Series maintains a filtration efficiency of over 99% for target particles, directly extending oil service life and reducing the need for frequent oil changes. For systems with sensitive components like servo valves or precision cylinders, this level of filtration is not just beneficial—it’s essential.

② Reliable Construction for Harsh Industrial Environments

Industrial settings are unforgiving, and the DF Series is built to withstand them:

Housing options: Choose between high-strength aluminum (for weight-sensitive applications) or steel (for maximum durability), both resistant to corrosion, impact, and vibration.

Pressure spike protection: Handles peak pressures up to 420 bar, preventing housing damage during sudden system pressure surges.

Temperature resilience: Operates flawlessly in temperatures ranging from -20°C to +110°C, making it suitable for outdoor use in cold climates or high-temperature manufacturing facilities (e.g., metal processing plants).

③ Maintenance Efficiency to Minimize Downtime

Downtime is a top concern for industrial operators, and the DF Series is designed to keep it to a minimum:

Tool-free element replacement: The series features a user-friendly spin-on design, allowing technicians to replace filters in minutes—no specialized tools required.

Proactive cloggoing indicator: Optional visual pressure gauges or electrical differential pressure switches provide real-time alerts when the filter element is nearing capacity, enabling scheduled maintenance instead of emergency shutdowns.

Cost-effective operation: The long-lasting filtration media reduces element replacement frequency by up to 30% compared to competitors, lowering annual maintenance costs while improving system reliability.

④ Flexible Configurations for Tailored Solutions

Every industrial application has unique needs, and the DF Series adapts accordingly:

Port versatility: Available with port sizes from ½” to 4”, compatible with NPT, BSP, or SAE flanges to match any system’s flow requirements.

Optional accessories: Enhance functionality with bypass valves (to maintain system operation during filter changes), contamination sensors (for real-time oil condition tracking), or custom mounting brackets (for tight installation spaces).

Material compliance: For specialized industries like food processing or marine, stainless steel housing options meet strict regulatory standards.

3. Trusted Across Critical Industries

The DF Series has earned its reputation as a reliable filtration solution in sectors where hydraulic failure is not an option:

Mining & Construction: Protects excavators, loaders, and bulldozers from dust and abrasive particles, ensuring continuous operation in remote, harsh sites.

Automotive Production: Keeps hydraulic oil clean in stamping machines and robotic assembly lines, supporting high-volume, 24/7 production schedules.

Renewable Energy: Maintains the integrity of wind turbine pitch and yaw hydraulic systems, critical for maximizing energy output and minimizing maintenance visits to remote wind farms.

Agriculture: Shields harvesters, tractors, and irrigation equipment from dirt and crop debris, ensuring reliable performance during peak farming seasons.

4. The Shengda Advantage: More Than Just a Filter

Choosing the DF Series means partnering with a leader in fluid technology with over 27 years of expertise:

Global quality standards: Fully compliant with ISO 16889 (hydraulic filter performance) and CE certifications, guaranteeing consistent quality and safety across all models.

Localized support: Shengda worldwide network of service centers provides fast access to replacement parts, technical support, and on-site training—ensuring minimal disruption if issues arise.

Sustainable design: The DF Series aligns with environmental goals, featuring recyclable filter elements and a low-pressure-drop design that reduces pump energy consumption, lowering both operational costs and carbon footprint.
