Product Introduction

• Brand: MECAN
• Product Name: WB2 Series Mechanical Seal
• Model: WB2-30
• Material: Silicon Carbide-Silicon Carbide-PTFE-304 Stainless Steel
• Shaft/Sleeve Outer Diameter: 1.18in (30mm)
• Quantity: 1 Set
• Application: Equipment Handling Strong Acids, Strong Oxidants, and Corrosive Media

Product Features

• Constructed from silicon carbide, silicon carbide, PTFE, and 304 stainless steel, this seal offers superior resistance to strong acids, strong oxidants, and other corrosive media, making it ideal for harsh chemical environments.
• With a precise 1.18in (30mm) shaft/sleeve outer diameter, it fits accurately into compatible equipment, guaranteeing optimal sealing performance.
• The external single-face design with multi-spring and PTFE bellows structure is internally balanced and non-pusher, providing good floatability and reliable sealing even under dynamic operating conditions.
• It operates efficiently within a temperature range of 0~120°C, enabling reliable performance in moderate-temperature applications involving corrosive fluids.
• With a maximum pressure tolerance of 0.80MPa, it maintains a reliable seal in relevant pressure processes, preventing fluid leakage and ensuring operational efficiency and safety.
• As a comprehensive set, it includes all components needed for a complete seal replacement, eliminating the need for separate part sourcing and ensuring compatibility.

Usage Instructions

1. Ensure the equipment is shut down and isolated from all power sources before starting the installation process.
2. Remove the existing seal (if present) and thoroughly clean the shaft, sleeve, and seal cavity to remove any debris, residue, or old sealing material.
3. Inspect the new MECAN WB2 series mechanical seal set for any visible damage or defects. Verify that the shaft/sleeve outer diameter (1.18in/30mm) matches your equipment’s specifications.
4. Install the seal according to the manufacturer’s guidelines, ensuring proper alignment and seating. Pay close attention to the correct orientation of all seal components, especially the PTFE bellows and multi-spring, to maintain sealing integrity.
5. Reassemble the equipment and conduct a leak test under low pressure initially. Gradually increase the pressure and monitor the seal for any signs of leakage or abnormal operation.
6. For detailed installation procedures, refer to the mechanical seal installation technical conditions. Perform periodic inspections during routine maintenance to check for wear, damage, or leakage. Replace the seal set promptly if any issues are detected to avoid equipment damage or operational failures.
