Product Introduction

• Brand: MECAN
• Product Name: CR/CRN Series Mechanical Seal
• Model: Grundfos CR/CRN-16 Silicon Carbide-Silicon Carbide-Fluororubber
• Shaft/Sleeve Outer Diameter: 0.63in (16mm)
• Quantity: 1 Set
• Application: Grundfos CR/CRN Series Pumps

Product Features

• Constructed from silicon carbide, silicon carbide, and fluororubber, this mechanical seal offers superior resistance to wear, corrosion, and chemical exposure, making it ideal for the demanding conditions in Grundfos CR/CRN pumps.
• It operates efficiently within a temperature range of -30~180°C, enabling reliable performance in both low-temperature and high-temperature applications involving various fluids.
• With a maximum pressure tolerance of 1.0MPa, it maintains a tight seal in medium-pressure pumping processes, preventing fluid leakage and ensuring operational efficiency and safety.
• The cartridge design simplifies installation and maintenance, allowing for quick replacement and reducing equipment downtime. The precise 0.63in (16mm) shaft/sleeve outer diameter ensures a perfect fit in compatible Grundfos pumps.
• Specifically engineered for Grundfos CR/CRN series pumps (including CR1, CR3, CR5, CRN1, CRN3, etc.), it guarantees optimal sealing performance and compatibility, enhancing the reliability of these pumping systems.

Usage Instructions

1. Ensure the Grundfos pump is shut down and isolated from power sources before beginning installation.
2. Remove the old seal (if present) and thoroughly clean the shaft, sleeve, and seal cavity to remove debris, residue, or old sealing material.
3. Inspect the new MECAN CR/CRN mechanical seal set for any damage or defects. Verify that the shaft/sleeve outer diameter (0.63in/16mm) matches your pump’s specifications.
4. Install the cartridge seal according to the manufacturer’s guidelines, ensuring proper alignment and seating. The cartridge design allows for straightforward installation without the need for precise manual alignment of seal faces.
5. Reassemble the pump 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. 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 pump damage or operational failures.
