Mepco (Dunham Bush) S-472 Seal
The Mepco (Dunham Bush) S-472 Seal is a heavy-duty mechanical shaft seal engineered for 5/8-inch pump shafts, specifically designed for 56J motor frames in commercial and industrial HVACR systems. As a critical component in centrifugal pumps, this Type 21 mechanical seal utilizes a high-grade carbon-ceramic seating interface to prevent fluid leakage between the pump housing and the rotating shaft. The technical construction features Buna elastomers and stainless steel hardware (springs and metal components) to ensure structural integrity and chemical resistance during intensive service cycles.
For technicians servicing Marshall Engineered Products Co. (MEPCO) or Dunham Bush hydronic heating and cooling equipment, the S-472 provides a reliable drop-in replacement that maintains a lubricated interface between stationary and rotating parts. This 5/8" seal is essential for sustaining pressure in steam systems and hot water loops, minimizing downtime caused by gland leakage or face wear. Its corrosion-resistant design makes it suitable for diverse boiler feed and circulating pump applications where environmental durability is a priority.
Key Benefits:- Precision Fit: Specifically engineered for 5/8-inch pump shafts and 56J motor frame configurations.
- Material Grade: Features a Buna-N elastomer, carbon washer, and ceramic seat for superior sealing performance.
- Operating Stability: The stainless steel spring provides consistent face loading to handle system fluctuations.
- Broad Application: Compatible with various MEPCO pump models and Dunham Bush centrifugal pumps.
What is the primary application for the Mepco S-472?
This seal is primarily used in commercial pumps and hydronic systems to prevent coolant or water leakage along the drive shaft.
Does this seal include the seat and the rotating assembly?
The S-472 mechanical seal is typically supplied as a complete assembly including the head style C and seat type 1 components required for a full replacement.
Is the S-472 compatible with high-temperature steam systems?
Yes, it is designed for steam and hot water heating systems, provided the system fluids and temperatures are compatible with the Buna elastomers and carbon-ceramic faces.
