Stationary Parts Specifications and Dimensions

This document provides detailed dimensional data and specifications for stationary parts used in mechanical assemblies, focusing on components with and without O-rings, with anti-rotation pins, and with cups. The data is presented primarily in metric units (millimeters) and also includes a section with inch-based dimensions.

1. Stationary Parts with O-Ring

• Dimensions are given for various diameters (d1) ranging from 10 mm to 100 mm.
• Key parameters include diameters d6, d7, d8, and lengths L16, L1 DIN, L9, along with other dimensional parameters I4, I5, I6, I8.
• O-ring specifications are integrated into the dimensional data, indicating sealing features.
• Some sizes include additional features such as anti-rotation pins and housings conforming to EN 12756 standards.

2. Stationary Parts without Anti-Rotation Pin and Housing

• Dimensions are provided for parts supplied only in carbon material.
• Parameters include diameters d1, d6, d7 and lengths I4, I5, I6.
• These parts correspond to PF. L DIN and PF. L6 types.

3. Stationary Parts with Cup (Locking Ring Not Included)

• Dimensions cover diameters from 10 mm to 100 mm.
• Parameters include d1, d6, d7, d13, and lengths I4, I5, I6, I30.
• These parts are identified as PF. L13 type.

4. Stationary Parts Dimensions in Inches

• Equivalent inch-based dimensions are provided for diameters from 0.250 inch (6.35 mm) up to 4.000 inch (101.6 mm).
• Parameters include d1, d6, d7, d8, I4, I5, I6, and additional dimensions d10, I9, I10 for certain parts.
• Parts are categorized under types PF. L12, PF. A, PF. C11, PF. L22, and PF. T.

5. Standards and Norms

• Some parts conform to EN 12756 standard for mechanical seal stationary parts.
• Anti-rotation pin and housing dimensions are specified according to EN 12756.

Critical Information and Recommendations

• Material specification: Parts without anti-rotation pins are supplied only in carbon.
• Locking rings are not included with parts that have cups; they must be sourced separately.
• Dimensional accuracy is critical for proper sealing and mechanical fit; adherence to specified dimensions is mandatory.
• Selection of parts should consider the presence or absence of O-rings, anti-rotation pins, and cups based on application requirements.

Summary of Dimensional Parameters

Parameter	Description
d1	Main diameter of the stationary part
d6, d7, d8, d13	Secondary diameters related to sealing surfaces and housing fits
L1 DIN, L9, L16, L4, L7, L13, L50, L60	Lengths and axial dimensions relevant to installation and sealing
I4, I5, I6, I8, I9, I10, I30	Additional dimensional parameters for detailed fitting and sealing geometry

This structured dimensional data supports the design, selection, and manufacturing of stationary parts in mechanical seals and related assemblies, ensuring compatibility with standard housings and sealing elements.
