Stauff SFT-20 Spin-On Filter Heads

Description

Technical and Design Overview

The Stauff SFT-20 Spin-On Filter Heads are a robust and reliable solution for hydraulic filtration, specifically designed for Tank Top Spin-On applications. The body is manufactured entirely from aluminum, ensuring low weight and adequate mechanical strength for low-pressure circuits. This component plays a key role in controlling fluid contamination in hydraulic systems, providing a secure interface between the system and the filter element.

Operating Performance and Fluid Compatibility

From a performance standpoint, the SFT-20 series is engineered to support a maximum flow rate of 200 l/min (53 US GPM), operating effectively up to a maximum pressure of 7 bar (100 PSI). Thermal versatility is ensured by a wide operating temperature range from -30°C to +100°C (-22°F to +212°F). In terms of fluid compatibility, the filter heads are standardized for use with mineral oils, with compatibility for other fluids available upon request.

Connection Specifications and Dimensions

The SFT-20 model is characterized by NPT threaded connections. Specifically, the connection code “20” indicates a 1-1/2 NPT thread. From a dimensional standpoint, the interface for the filter element features a dual spigot mounting with G1-1/4 and 1-1/2-16 UN specifications, allowing proper coupling with the designated filter elements.

Clogging Indicator Configuration

The flexibility of the SFT-20 series is highlighted by the available options for the clogging indicator port, defined by the third part of the ordering code:

• Code 0: No clogging indicator port.
• Code 1: Drilled clogging indicator port, specifically for return-line applications. The standard port size is 1/8 NPT.
• Code 9: Special version.

Filter Element Compatibility

These filter heads are designed exclusively for use with SFCT-57/58 series filter elements. It is important to note that the bypass valve, set at 1.7 bar (25 PSI), is integrated directly into the filter element rather than into the filter head. The filter elements must feature a type A sealing profile. The filter element is not included with the filter head and must be ordered separately.
