Shaft Sleeve B075-4Cr13 for 1.5/1B-AH Heavy Duty Slurry Pump

B075-4Cr13 Stainless Steel Shaft Sleeve, Wear Protective Spare Part for 1.5/1B-AH Heavy Duty Slurry Pump

This B075 shaft sleeve is made of 4Cr13 martensitic stainless steel with heat treatment for high hardness. It is sleeved on pump shaft to prevent shaft from packing friction and slurry corrosion. Fully interchangeable with OEM spare parts, widely applied to mining, sand washing and power plant slurry pumps.

1. Basic Model Code Explanation

1. Part No. B075The prefix B represents pumps with B-series bearing assembly; 075 is OEM drawing number of shaft sleeve. It is a core protective component sleeved on the pump main shaft.

2. Material Grade 4Cr134Cr13 is martensitic stainless steel. It features high hardness after heat treatment, excellent wear resistance and moderate corrosion resistance, effectively resisting friction from packing and slight slurry corrosion.

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 DesignCylindrical integral sleeve structure with precise inner hole matching the outer diameter of pump shaft. Step positioning design ensures accurate axial installation. Its outer surface directly contacts packing ropes, isolating the pump shaft from friction, slurry and corrosion to avoid shaft abrasion damage.

2. Manufacturing ProcessPrecision bar turning, followed by quenching and tempering heat treatment to improve surface hardness. Outer friction surface undergoes fine grinding to achieve smooth finish and low friction coefficient. Full dimensional interchangeability with OEM spare parts for direct replacement.

3. Material Performance4Cr13 stainless steel obtains high surface hardness after heat treatment. It can withstand long-term reciprocating friction with packing, and resist slight acid slurry corrosion. Compared with grey cast iron, it has far better wear and anti-corrosion performance.

4. Quality ControlStrict dimensional tolerance inspection, surface flaw detection to eliminate cracks and pits. Uniform smooth outer surface reduces packing wear and extends service life of both sleeve and packing.
