331763 Lip Seal with FKM

The 331763 Lip Seal with FKM by Blackmer is a high-performance sealing component designed for use in positive displacement and sliding vane pump applications. Manufactured by Blackmer, a trusted industry leader in pump components, this lip seal features FKM (fluoroelastomer) material, offering excellent chemical resistance, high-temperature durability, and long-lasting sealing performance.

The 331763 Lip Seal is constructed with a durable elastomer lip mounted on a robust metal casing, providing a precise seal interface with the pump shaft. It is suitable for operating temperatures up to 200°C (392°F) and resists a wide spectrum of chemicals including acids, oils, and hydrocarbons. The seal has an overall diameter of approximately 2.75 inches (70 mm) and a thickness of 0.25 inches (6 mm), designed to fit standard pump shafts ranging from 1.25 to 1.75 inches (32-44 mm) in diameter.

Key features include:

• Made from FKM fluoroelastomer for high chemical and temperature resistance
• Overall dimensions: 2.75 inches diameter, 0.25 inches thickness
• Operational temperature range: -20°C to 200°C (-4°F to 392°F)
• Designed for pump shaft sizes between 1.25 and 1.75 inches (32-44 mm)
• Seals against lubricant loss and contaminant ingress while maintaining shaft alignment
• Constructed for easy installation with proper orientation and cleanliness

This lip seal is ideal for use in demanding industrial processes where chemical exposure and high temperatures are prevalent. It is suitable for applications in chemical processing, oil and gas, and other environments requiring reliable pump sealing. The 331763 Lip Seal with FKM by Blackmer is designed for professionals seeking an affordable yet durable component to maintain pump integrity and extend equipment lifespan, making it an essential part for those working within a strict budget for reliable pump sealing.

The seal ships with installation instructions and compatible mounting hardware. It does not include mounting tools or lubricant; users should prepare by inspecting pump shafts for wear, cleaning sealing surfaces, and applying a suitable lubricant before installation.

Care instructions include inspecting the seal periodically for signs of wear or damage, replacing it if any degradation is observed, and maintaining the operating environment to prevent contamination. The FKM material provides high chemical resistance, but the seal should be replaced if exposed to incompatible chemicals beyond its specified range. No specific warranty is provided, but proper handling and installation ensure optimal long-term performance.
