Product catalog summary

Overview: The document provides comprehensive specifications and guidelines for the Vacuum Pad Standard Series, designed for handling various work-piece types such as flat, round, and small items. It emphasizes the versatility in pad sizes, materials, and holder types to accommodate different industrial applications.

Specifications:

Pad Shapes and Sizes: Available in three shapes - Small, General, and Deep, with sizes ranging from ø0.7mm to ø200mm, suitable for specific work-piece types.
Materials: Ten material options including Nitrile rubber, Silicone rubber, and Conductive NBR, tailored for diverse environmental and application needs.
Holder Types: 14 holder types, including copper alloy-free options for low ozone concentration environments.

Procedures:

Stroke Length Selection: Spring holders offer stroke lengths from 3 mm to 50 mm, depending on the model.
Model Designation: A detailed coding system allows precise customization of pad size, type, material, and connection configuration.

Norms and Recommendations:

Material Suitability: Certain materials like Conductive Silicone rubber are limited to specific sizes and applications.
Environmental Considerations: Recommendations for using specific materials in low ozone or moisture-containing environments.

Key Data from Tables and Diagrams:

Pad Dimensions: Detailed dimensions for small, standard, and deep type pads, including weight specifications.
Connection Configurations: Various connection types and their applicable pad sizes, ensuring compatibility with different setups.

Critical Information:

Exclusions: Some materials are not suitable for ozone environments, and certain pad types are not available in all materials.
Compliance: Specific models are noted as non-compliant with the Revised RoHS directive.

Procedures and Standards:
The document specifies the tightening torque for pad holder fixing bulkhead nuts, which is between 4.5 and 6 N·m. It also mentions the availability of copper alloy-free materials and compliance with RoHS standards.

Recommendations:
Users are advised to refer to the Pisco website for additional information such as weight details and to contact the company for specific fitting model codes for options like "-S3" which differ from standard products.

Connection Types:
The vacuum pads are available with various connection configurations, including push-in fittings, barb fittings, and screw types. The document provides model codes for each configuration and specifies the appropriate connection type for each pad diameter.

Key Data from Tables:
The tables in the document provide detailed measurements for each model, including pad diameter, stroke length, and spring force. Values in parentheses indicate dimensions for deep type pads. The tables also list model codes for pad screws, washers, and other components necessary for assembly.

Critical Information:
The document highlights the importance of using the correct pad material in specific environments, noting that certain materials are not suitable for use under ozone conditions. It also emphasizes the need to replace rubber packing when removing hexagonal socket head bolts.

Specifications and Recommendations:
1. Pad Positioning: Ensure the vacuum pad lip lightly touches the workpiece to prevent early deformation or damage. Small vacuum pads require precise positioning.
2. Porous Workpieces: Use a vacuum system with appropriate specifications and a larger effective cross-section area to counteract suction force drops. Small vacuum pads can help reduce air leakage.
3. Large Workpieces: For large glass or circuit boards, select pads that provide sufficient suction force to prevent bending during lifting.
4. Soft and Inclined Workpieces: Use Long Stroke holders for varying heights and Free Holders for inclined workpieces.
5. Rotary Movement: Ensure screws are secure to prevent pad detachment during rotary movements. Apply a safety factor of 1/8 for vertical lifting in rotary or lateral movements.

Vacuum Pad Selection:
1. Pad Materials: Options include Nitrile, Silicone, Urethane, Fluoro, and Conductive rubbers, each with specific applications.
2. Pad Types: Standard, Bellows, Multi-Bellows, Soft, Skidproof, Ultrathin, and Flat types are available, with varying diameters from 0.7mm to 200mm.

Safety Instructions:
1. General Safety: Follow ISO 4414 and JIS B 8370 standards. Improper use can lead to serious injury or damage.
2. Product Handling: Only experienced personnel should handle pneumatic equipment. Ensure safety measures are in place before maintenance.
3. Environmental Conditions: Avoid using products outside specified conditions, such as exposure to corrosive gases or excessive vibrations.

Warranty and Disclaimer:
1. Warranty Coverage: Includes free replacement or repair for defects caused by PISCO's responsibility. Excludes damages from natural disasters, misuse, or unauthorized modifications.
2. Liability Limitations: Compensation is limited to the product's purchase price, excluding indirect losses or damages.

Piping Guidelines:

Compressed air contains impurities that can reduce product performance. Use an aftercooler and dryer to improve air quality.
Avoid using lubricators on products.
Install a filter with 5μm or better filtration to prevent rust and foreign substances from causing malfunctions.
Ensure pipes are free from dust and drain before installation to prevent malfunctions.
Use an Insert Ring when inserting ultra-soft tubes into push-in fittings to prevent tube escape and fluid leakage.
Avoid applying loads such as twists or impacts on fittings and tubes to prevent damage.
Install protective covers for products exposed to direct sunlight.
Verify the correct piping of vacuum generators to avoid product damage.
Position pressure sensors close to the vacuum system to reduce plumbing resistance and ensure accurate readings.
Use shorter, wider plumbing for vacuum systems to ensure adequate suction flow rate.
Ensure non-PISCO brand tubes meet specified outer diameter tolerances.

Tube Insertion and Disconnection:

Ensure tube ends are cut at right angles without scratches or deformations.
Insert tubes fully into push-in fittings to prevent leakage.
For compression fittings, pass the tube through the nut, insert the barb, and tighten with the appropriate torque.
Ensure no air pressure is present before disconnecting tubes.
Use proper tools to loosen nuts and disconnect tubes.

Fitting Installation:

Use appropriate tools to tighten fittings without deforming lock-claws.
Refer to specified tightening torques to avoid thread damage or fluid leakage.
Adjust tube direction within torque limits during installation.
Ensure no leakage after tightening nuts.

Handling PISCO Products:

Avoid impacts that may damage products and cause fluid leakage.
Use products within the specified operating temperature range.
