Stauff In-Line Filters SRFL-S Series: Efficiency and Compact Design for Hydraulic Systems
The Stauff SRFL-S series in-line filters represent the Simplex (single-filter) solution designed to deliver maximum performance in in-line hydraulic applications. Engineered to handle high flow rates and constant operating pressures, this series stands out for its compact construction and ease of access during maintenance operations.
Design Features and Performance
The SRFL-S series is developed to support nominal flow rates of up to 7,000 l/min (1,850 US GPM) and maximum operating pressures of 14 bar (200 PSI). The assembly is of the in-line type with base mounting, making it ideal for stable integration into industrial piping systems. The filter elements are designed as baskets, a configuration that retains contaminants during element replacement, preventing accidental system contamination.
Filter Elements and Maintenance
High contaminant removal efficiency is ensured through the use of Stauff RE series replacement filter elements. These elements provide a high dirt-holding capacity, resulting in extended service life and reduced maintenance costs. For applications requiring filter condition monitoring, visual and electrical differential clogging indicators are available.
Materials and Fluid Compatibility
The versatility of the SRFL-S filters is ensured by the choice of construction materials and sealing options:
- Filter housing: Standard carbon steel, with stainless steel available on request.
- Seals: Available in NBR (Buna-N®) or FKM (Viton®), ensuring compatibility with various fluid types.
- Media compatibility: Suitable for mineral oils, lubricating oils, and—specifically in the SRFL-SW version—for industrial water circuits.
Connection Options
To meet international standards, the filter housings support multiple flange configurations:
- ANSI flanges.
- DIN flanges.
- SAE flanges (ISO 6162-1/2).
