Mepco (Dunham Bush) ML11775 Seal Kit
The Mepco (Dunham Bush) ML11775 Seal Kit is a critical service component engineered for professional pump rebuild applications on the air pump side of high-capacity hydronic and vacuum heating systems. Designed for field reliability, this kit is specifically compatible with Mepco RC06, RC07, and RC09 close-coupled centrifugal pumps, as well as RP06, RP07, and RP09 in-line models utilizing 143-215JM frame motors. It is also the standard service solution for Vent Rite G7V and G9V pump frames (3 HP and above) and Mepco C5 and E3 series vacuum units. Containing a 1.250-inch mechanical seal, shaft sleeve, and high-grade Buna-N O-rings, the ML11775 ensures a pressure-tight barrier to prevent refrigerant or fluid loss, maintaining system head pressure and preventing atmospheric contamination. This comprehensive OEM replacement kit includes all necessary hardware—such as the impeller key, cap screws, and silicone—to restore factory-spec sealing efficiency and minimize technician downtime during critical maintenance intervals.
Key Benefits for HVACR Contractors- Broad Compatibility: Drop-in fit for Dunham Bush RC and RP centrifugal series and Vent Rite vacuum pump systems.
- Complete Rebuild Solution: Includes Buna-N mechanical seals, shaft sleeves, and gaskets to eliminate the need for sourcing individual hardware.
- Industrial Durability: Specifically rated for 143-215JM motor frames, ensuring structural integrity under high torque and thermal stress.
- Leak Prevention: Precision-engineered elastomer seals prevent fluid migration, protecting motor bearings and improving overall pump efficiency.
What shaft size does the ML11775 seal kit support?
This kit is designed for a 1.250-inch shaft diameter, common in 3 HP and larger pump frames used in commercial steam and hydronic applications.
Is this kit compatible with Vent Rite units?
Yes, it is the designated seal rebuild kit for Vent Rite G7V and G9V pump frames when equipped with 143-215JM motor frames.
What materials are used for the O-rings and gaskets?
The kit utilizes Buna-N (Nitrile) elastomers, which provide excellent resistance to water, oils, and standard refrigerants found in vacuum heating systems.
