UHB Series Chemical Processing Pumps
Corrosion & Abrasion Resistance Solutions
The UHB Series Chemical Processing Pumps are cantilever-type, single-stage, single-suction centrifugal pumps engineered for handling corrosive and abrasive media containing fine particles. Available in two variants—UHB-ZK (standard) and UHB-ZKG (high-temperature)—these pumps are ideal for demanding industrial applications across diverse sectors.
Features and Benefits of UHB Pumps
Exceptional Wear Resistance
UHB-ZK: Flow components are lined with Ultra-High Molecular Weight Polyethylene (UHMW-PE), offering unmatched wear resistance—4x higher than nylon (PA66) or PTFE, and 7–10x superior to stainless steel.
UHB-ZKG: Utilizes modified UHMW-PE for extreme conditions, tolerating temperatures up to 180°C and abrasive slurries with ≤40% solids.
Superior Corrosion Resistance
Resists a wide range of corrosive media, including acids (up to 80% sulfuric acid, 50% nitric acid), alkalis, salts, and organic solvents. Maintains stability even after prolonged exposure (tested in 80+ solvents at 20–100°C).
Robust Impact Resistance
UHMW-PE boasts the highest impact strength among engineering plastics, 5x greater than ABS, and retains performance at -196°C.
Anti-Clogging Design
Semi-open impeller (no front shroud) and optimized flow path ensure smooth passage of particles, minimizing blockages.
Low Noise & Self-Lubricating
UHMW-PE’s vibration-damping properties reduce operational noise. A low friction coefficient (0.07–0.11) ensures self-lubrication, outperforming lubricated metals.
Non-Toxic & Hygienic
Chemically inert material suitable for food, pharmaceutical, and water treatment industries.
Advanced Sealing Technology
K-Type Dynamic Seal: Combines an auxiliary impeller (generating negative pressure to prevent leakage) with a fluororubber shutdown seal.
* Includes optional cooling water jacket (≤0.05MPa pressure) to extend seal life in high-temperature or abrasive environments.
Alternative Seals: K1, T/T1 (packing), and C3 custom seals available.
