Double Pump Seal 560D with 14~70mm Size Range 1.0–1.7 MPa Pressure and 12m/s Speed for High-Pressure Applications

The 560D Double Pump Seal is a pressurized dual mechanical seal arrangement, typically configured in a tandem or back-to-back orientation. It is engineered to provide a secondary containment seal for handling volatile, hazardous, or abrasive fluids. The design incorporates a barrier fluid system between the primary and secondary seals, which is maintained at a pressure higher than the process fluid. This configuration ensures that any leakage from the primary seal is contained, preventing fugitive emissions to the atmosphere. The 560D is constructed for service in demanding applications within the petrochemical, hydrocarbon processing, and chemical industries, complying with API 682 standards for shaft sealing systems.

Features:

• Double faces
• Single spring
• Unbalanced seal
• Elastomer bellows

The 560D is a dual seal in a back-to-back arrangement with an EA560 base. Therefore, the seal combines the advantages of the EA560 with the advantages of a dual seal.

Frequently Asked Questions:

Q1: What is the primary safety function of the Double Pump Seal 560D?

A1: It is designed as a dual seal system to provide a secondary containment barrier, preventing hazardous fluid leakage to the atmosphere in case the primary seal fails.

Q2: In which fluid services is the Double Pump Seal 560D typically specified?

A2: It is specified for volatile organic compounds (VOCs), hazardous chemicals, abrasive slurries, and light hydrocarbons in refinery, petrochemical, and chemical processing applications.

Q3: What are the standard pressure and temperature ratings for the Double Pump Seal 560D?

A3: Standard ratings typically include a maximum operating pressure of 1.0 MPa and a temperature range from -20°C to 120°C, with higher temperature capabilities available through specific material selections.

Q4: What materials are commonly used for the sealing faces in the Double Pump Seal 560D?

A4: Common face material combinations include Silicon Carbide versus Silicon Carbide and Tungsten Carbide versus Carbon, selected based on the specific application's abrasion and corrosion requirements.

Q5: How does the Double Pump Seal 560D comply with industry standards?

A5: The seal is engineered to meet API 682 standards for shaft sealing systems, ensuring compatibility with standardized pumping equipment in regulated industries.

Q6: What is the recommended barrier fluid pressure for the Double Pump Seal 560D in a tandem arrangement?

A6: In a tandem arrangement, the barrier fluid is typically maintained at a pressure lower than the process fluid to ensure controlled containment of any primary seal leakage.

Q7: Can the Double Pump Seal 560D be configured for different seal arrangements?

A7: Yes, it is available in various arrangements including tandem (Arrangement 2) and back-to-back (Arrangement 3) configurations to meet specific process containment needs.
