Description

The 331805 Mechanical Seal by Blackmer is a high-performance sealing component designed for pump systems requiring reliable containment of fluids. This product is specifically engineered to deliver durable and leak-proof operation within demanding industrial environments.

This part is no longer being manufactured. Once our current inventory is depleted, it will be unavailable.

This mechanical seal features a stainless steel casing for structural integrity and corrosion resistance, complemented by elastomeric components such as EPDM or Viton for flexibility and sealing performance. The seal incorporates a quartz or ceramic face, selected for high durability against wear and chemical exposure. Its standard dimensions include a bore size of 25 mm (1 inch) to fit common pump shafts and an external diameter of approximately 70 mm (2.75 inches). It is constructed to withstand temperatures up to 200°C (392°F) and pressures exceeding 15 bar (218 psi), making it suitable for high-temperature and high-pressure applications. The design includes stationary and rotary components, with a secondary sealing element to prevent leakage and maintain system integrity. The seal is designed for straightforward installation, compatible with various positive displacement and sliding vane pump systems, with a recommended shaft diameter tolerance of ±0.1 mm.

The 331805 Mechanical Seal is ideal for use in chemical processing, water treatment, and fluid transfer industries. It is especially suitable for applications requiring high resistance to temperature, pressure, and corrosive liquids, serving budget-conscious operations that demand dependable pump sealing solutions. Its robust construction ensures reliable performance over extended operational periods.

Each package contains the mechanical seal assembly along with detailed installation instructions. Mounting components or pump-specific adapters are not included and may be required for installation depending on the pump model and configuration.

Maintenance recommendations include cleaning elastomeric parts with compatible solvents, inspecting seal faces periodically, and verifying proper shaft alignment prior to installation. Routine inspections are advised every 12 months or after exposure to extreme conditions to ensure longevity and optimal performance of the 331805 Mechanical Seal.
