A single-stage, single-suction cantilever centrifugal slurry pump engineered for high corrosion and abrasion resistance. The HTB‑ZK series uses acid‑resistant ceramic liners for the wet end and offers a rugged cast‑iron external armor to protect the casing, delivering long service life when handling corrosive slurries containing suspended solids.
Key features
- Capacity: 5 to 240 m3/h
- Head range: 10 to 60 m
- Wet-end materials: acid-resistant engineering ceramics for pump body and cover
- Impeller options: engineering ceramic or engineering-grade plastics (material selection depends on application)
- External protection: cast iron armor on the pump housing
- Shaft seal: back-blade decompression combined with a fluorine‑rubber oil seal ring, or auxiliary‑impeller centrifugal seal
- Temperature limits: service temperature up to 100°C (impeller plastic temperature limits depend on material and conveyed medium); allowable temperature difference < 50°C
- Exclusions: not suitable for hydrofluoric acid or hot, concentrated caustic lyes
Performance and reliability
Designed for corrosive, abrasive slurries, this pump balances chemical resistance and wear durability. The ceramic-lined flow path and optional ceramic impeller minimize erosion and reduce maintenance frequency. Tight shaft sealing options reduce leakage and prevent contamination of the pumped medium.
Typical applications
Mining, mineral processing and smelting; chemical and petrochemical processes; pesticide and dye manufacturing; wastewater and sewage treatment; any industrial process requiring transfer of corrosive liquids with suspended solids (except where hydrofluoric acid or hot concentrated alkali are present).
Installation & maintenance notes
The compact cantilever design simplifies installation and eliminates the need for submerged bearings. Use compatible impeller materials for elevated temperatures or aggressive chemicals. Routine inspection of seals and periodic verification of ceramic liner integrity will maximize service life.
If you need assistance selecting the correct impeller material or seal configuration for a specific slurry composition or operating point, provide the fluid chemistry, solids concentration and particle size distribution so the best configuration can be recommended.
