Centrifugal Pump Parts
Seal Kits
Seal kits are one of the most commonly replaced pump components and are critical for preventing leaks and protecting internal parts. At Southeast Pump & Equipment, seal kits are typically supplied as complete assemblies to ensure proper fit and reliable performance. Depending on the pump and brand, most seal kits include the mechanical seal, the volute gasket, the backplate gasket, and the impeller hardware. Replacing seals as a kit reduces installation errors, minimizes downtime, and helps extend overall pump life.
Shafts/Shaft Sleeves
Shafts and shaft sleeves maintain alignment and protect the rotating assembly from wear caused by seals and packing. Manufacturers design shaft sleeves to be sacrificial, allowing you to replace them without changing the entire shaft. Southeast Pump & Equipment supplies shafts and sleeves matched to specific pump frames, motor types, and materials. Inspecting shaft sleeves during seal replacement is essential, as worn sleeves can quickly damage new seals and shorten bearing life.
Impeller Kits/Stack Kits
Impeller kits restore hydraulic performance lost due to wear, erosion, corrosion, or cavitation. These kits typically include the impeller, required gaskets, and mounting hardware. For multistage pumps, stack kits replace the entire impeller assembly to restore original flow and head. Southeast Pump & Equipment supplies Grundfos impeller kits selected by model, construction code, and trim diameter to ensure proper balance, efficiency, and long-term reliability.
Bearing Frame Assembly/Bearing Frame Kits
Bearing frames support the rotating assembly and are essential for stable, low-vibration operation. When bearings fail, vibration and misalignment often follow. Southeast Pump & Equipment offers complete bearing frame assemblies or bearing frame kits, depending on service needs. Kits typically include bearings and moisture seals, while complete assemblies provide a faster replacement option. Proper bearing support protects shafts, seals, and impellers from premature failure.
Pump Casings
Pump casings form the pressure boundary and direct fluid flow through the pump. Over time, corrosion or erosion can reduce efficiency or cause leaks. Southeast Pump & Equipment supplies replacement pump casings manufactured to exact tolerances to restore internal clearances and performance. Replacing a damaged casing can significantly extend pump life, especially when paired with new wear components, without requiring complete pump replacement.
Gaskets/O-Rings
Gaskets and O-rings ensure proper sealing between pump components and help maintain pressure integrity. Southeast Pump & Equipment supplies OEM-grade gaskets and O-rings designed for specific pump sizes and construction codes. Replacing gaskets whenever you open a pump helps prevent leaks, uneven loading, and rework. Using the correct materials improves reliability and supports long-term performance in commercial and industrial pump systems.
