Expeller Ring B029-G01 for 1.5/1B-AH Slurry Pump

B029-G01 Grey Cast Iron Expeller Ring, Dynamic Seal Matching Spare Part for 1.5/1B-AH Slurry Pump

This B029 expeller ring is cast from G01 grey cast iron, a stationary matching part for expeller dynamic seal system of 1.5/1B-AH slurry pump. It forms sealing clearance with rotating expeller to prevent slurry entering stuffing box. Fully interchangeable with OEM spare parts, widely applied in mining, sand washing and power plant slurry transportation pumps.

1. Basic Model Code Explanation

1. Part Number B029Letter B represents slurry pumps equipped with B-series bearing assemblies; 029 is the OEM drawing number of expeller ring. It is a matching static component used together with the rotating expeller for dynamic sealing.

2. Material Grade G01G01 refers to grey cast iron HT200. It features good casting performance, easy machining and stable structural rigidity. As a static structural part without severe direct slurry erosion, grey cast iron meets its service requirements perfectly.

3. Applicable Pump ModelSpecially matched for 1.5/1B-AH horizontal heavy-duty slurry pump with 1.5-inch suction inlet and 1-inch discharge outlet.

2. Structural & Processing Features

1. Structural DesignIt is an annular static wear part installed stationary around the expeller. It forms a tiny clearance gap with the rotating expeller blades. When the expeller spins, the expeller ring cooperates to build effective centrifugal dynamic sealing, stopping abrasive slurry from permeating into the stuffing box and protecting packing and shaft sleeve from wear.

2. Manufacturing TechnologyIntegral sand casting forming. All fitting surfaces and inner circular surfaces are precisely lathe processed. The dimensions are fully interchangeable with original OEM spare parts for direct replacement without modifying other pump accessories.

3. Material PerformanceG01 grey cast iron provides stable support as a static auxiliary sealing component. It only bears slight indirect slurry flushing instead of strong particle scouring, so it does not require high-chromium wear-resistant material like A05 flow parts.

4. Quality ControlAll casting defects including sand holes and shrinkage cavities are fully repaired and polished. Smooth mating surfaces ensure tight assembly and stable sealing clearance.
