Expeller D028‑G01 is rotating auxiliary impeller for 4/3C‑XAH slurry pump expeller sealing system. Cooperates with expeller cover to realize pressure relief without external flush water. Effectively reduces shaft‑end slurry leakage for mining and tailings transfer, fully interchangeable with standard 4/3C‑XAH pump assemblies.
Expeller: Auxiliary impeller, the rotating core component of expeller pressure‑relief sealing assembly.
D028: Exclusive part number of expeller for 4/3C‑XAH slurry pump.
G01: Material grade for cast structural housing component.
4/3C‑XAH Slurry Pump: Matched heavy‑duty horizontal slurry pump, applicable only for expeller‑seal pump configuration.
Integrally cast rotating component with backward‑curved vane geometry. Precision‑machined central bore ensures accurate fit with shaft sleeve. The vanes generate centrifugal force during rotation to counteract internal pump chamber pressure. Tight clearance control is required when cooperating with expeller cover. Heavy‑duty cast construction withstands particle erosion. It is a rotating consumable spare part exposed to slurry abrasion.
Custom‑fit for 4/3C‑XAH horizontal slurry pump. Works in combination with expeller cover, expeller cover locating sleeve, shaft sleeve, labyrinth sleeve and bearing assembly. It replaces stuffing‑box packing sealing system. Not suitable for pumps assembled with packing‑seal structure only.
Designed for mineral processing, tailings transportation, sand‑gravel conveying operations without external flush‑water supply. It offsets pump internal pressure and minimizes slurry leakage at shaft seal position. Suitable for media mixed with hard abrasive solid particles.
