D075‑3Cr13 Shaft Sleeve for 6/4D‑G gravel slurry pump, made of 3Cr13 stainless steel. High surface hardness against friction and slurry erosion, OEM interchangeable, reliable protective component for pump shaft.
D075: Shaft sleeve part number for 6/4D‑G gravel slurry pump
3Cr13: Martensitic stainless steel material grade, offering good hardness, wear‑resistance and corrosion resistance
6/4D‑G: Horizontal gravel slurry pump model
Adopts integral cylindrical structure with fine outer‑surface finishing. Heat‑treatment process improves surface hardness to resist friction from packing and solid‑particle scouring. It protects main pump shaft from abrasion and corrosion caused by slurry medium. Strict dimensional tolerance ensures precise fit with pump shaft, easy for disassembly and on‑site replacement.
Specially designed for 6/4D‑G horizontal gravel slurry pump. Fully interchangeable with OEM shaft sleeve. Perfectly matches original shaft, stuffing box, lantern ring and packing gland without secondary modification.
Mainly used in sand‑gravel pumping, river dredging, sand washing plant and coarse‑particle tailings transportation. It bears friction from packing seal, prevents slurry from eroding the pump main shaft, reduces shaft damage risk and lowers maintenance cost of main shaft assembly.
