Bell & Gossett 186835LF Seal Kit
The Bell & Gossett 186835LF Seal Kit is a critical maintenance component designed specifically for Series 60 inline centrifugal pumps. This lead-free (LF) mechanical seal features an EPT (Ethylene Propylene Terpolymer) bellows, making it the standard choice for hydronic heating and cooling systems where resistance to specific chemical additives and high temperatures is required. Utilizing a carbon-silicon carbide or carbon-ceramic interface, this 1-inch diameter seal ensures a precision fit for the B&G Series 60 pump shaft, preventing leaks and maintaining system pressure. As a genuine B&G replacement part, it meets strict metallurgical standards for potable water applications. This kit simplifies field repairs by providing a factory-spec stationary seat and rotating seal assembly, ensuring pump seal replacement aligns with original equipment tolerances. Proper installation of this mechanical seal assembly extends the service life of the pump volute while protecting the motor shaft from operational wear and moisture intrusion.
Key Benefits- Broad Fluid Compatibility: The EPT elastomers provide superior performance in hot water applications compared to standard Buna-N configurations.
- Lead-Free Construction: Certified for use in systems where potable water safety and compliance with modern plumbing codes are required.
- Precision Engineering: Designed for an exact fit on Bell & Gossett Series 60 circulators, reducing mechanical vibration and face wear.
- High Thermal Resistance: Capable of handling the cycling temperatures typical of commercial hydronic HVAC systems without degrading.
Is the 186835LF seal compatible with oil-based fluids?
No, EPT (EPDM) seals are designed for water and glycol solutions; they will fail if exposed to petroleum-based oils or lubricants.
What is the difference between this and the standard 186835?
The "LF" suffix indicates lead-free construction, making this version suitable for potable water applications where the standard 186835 may not be permitted.
Does this kit include the spring and bellows?
Yes, this constitutes a complete mechanical seal kit, including the rotating bellows assembly and the stationary insert.
