Mepco (Dunham Bush) ML11763 Seal Kit
Professional-grade Mepco (Dunham Bush) ML11763 Seal Kit, specifically engineered for the return/water side of high-performance hydronic and steam systems. This maintenance kit is a direct cross-reference for part 11ML11763 and is essential for the overhaul of Mepco RC05 and RC06 close-coupled centrifugal pumps, as well as RP05 and RP06 in-line models utilizing 56 frame motors. As a veteran technician knows, maintaining the integrity of the water side is critical for preventing vacuum loss in heating systems. This pump rebuild kit includes a 5/8-inch (0.625") P66 ceramic/Buna mechanical seal and high-tolerance Buna-N adapter O-rings, providing a leak-proof barrier compatible with standard HVAC fluids. It is also the correct specification for Vent Rite G5V and G6V pump frames up to 2 HP. Utilizing this OEM replacement seal ensures your centrifugal pump maintenance meets original factory tolerances, preventing premature bearing failure and optimizing motor efficiency.
- Direct System Compatibility: Exact fit for Mepco GS Series and vacuum heating pumps including the C5 and E3 series.
- Complete Service Kit: Includes the mechanical seal, O-rings, and gaskets required for a full return-side restoration.
- Industrial Durability: Features high-grade Buna-N elastomers for resistance to thermal cycling and common hydronic additives.
- Versatile Application: Validated for both close-coupled and in-line pump configurations with 56J frame motors.
Common Questions
Which side of the pump does the ML11763 seal kit serve?
This specific kit is designated for the return/water side. For vacuum systems requiring the air pump side, a different part number (typically ML11775) is required.

Yes, the ML11763 is the standard rebuild kit for Vent Rite G5V and G6V pump frames that utilize the 56J motor frame size.
How do I verify if I need a 5/8" or 1-1/4" seal kit?
The ML11763 is specifically for 5/8-inch (0.625") shaft diameters common on 56 frame motors. Always measure the pump shaft or verify the frame size on the motor nameplate before installation.
