توضیحات
Replace Grundfos Pump Single Spring Seal 16mm
Replace Grundfos Pump Single Spring Seal 16mm
The Replace Grundfos Pump Single Spring Seal 16mm is a non-OEM (aftermarket) mechanical seal designed as a functional and dimensional equivalent to the original single-spring seal used in specific Grundfos centrifugal pumps. This cartridge mechanical seal features a 16mm bore and utilizes a single spring design, engineered for direct replacement in compatible Grundfos pump models while offering cost-effectiveness and shorter lead times.
Core Product Features
Feature Description & Procurement Key
Shaft Diameter The primary dimension that must match exactly. The 16mm specification indicates the diameter of the pump shaft for which the seal is designed. This is the foremost and non-negotiable sizing parameter.
Spring Design Critical structural characteristic. Single Spring indicates the seal uses one large helical spring (as opposed to multiple small springs) to provide the closing force. This design affects the seal's dimensions and operational behavior.
Construction & Type Typically a Cartridge Seal. All components (rotary and stationary faces, spring, sleeve, O-rings) are pre-assembled into a single unit, simplifying installation and minimizing assembly errors.
Material Configuration The key determinant of service life. Must be selected based on the pumped fluid. Common configurations include:
• Seal Faces: Silicon Carbide / Carbon-Graphite (cost-effective for clean water) OR Silicon Carbide / Silicon Carbide (for abrasive media)
• Elastomer (O-Ring): NBR (for cold water, oils), EPDM (for hot water ≤ 120°C), FKM/Viton® (for chemicals, higher temperatures)
Procurement and Replacement Guide
Steps for Successful Replacement:
  1. Identify Source Information: Locate the pump's nameplate data (model e.g., CR5, CR10, CH2-30) and/or the physical old seal. This is the most reliable reference.
  2. Cross-Reference with Supplier: Provide the supplier with:
    • Optimal Data: Pump model + clear photos of the old seal
    • Key Dimensions: Confirm the 16mm shaft diameter and, if possible, provide the seal chamber's bore and depth
    • Operating Conditions: Specify the fluid (e.g., 60°C hot water, sandy water, 3% NaOH solution), along with its temperature and pressure
  3. Verify Supplier Expertise: Choose a specialized seal supplier who can provide detailed dimensional drawings and material certifications, confirming their product is a direct replacement design for Grundfos pumps.
Critical Note: Do not order based solely on the description "16mm single spring." It is essential to provide the supplier with clear photographs of the old seal (especially faces and side profile), measured dimensions, and complete operating conditions for final verification.
