Pompa Tahan Korosi UHMWPE Seri UHB
The UHB Series UHMWPE Corrosion Resistant Pump is a cantilever, single-stage, single-suction industrial pump designed specifically for handling chemically aggressive, corrosive, or reactive fluids. Unlike standard pumps, its casing is made of steel-lined ultra-high molecular weight polyethylene (UHMWPE), featuring thickened imported wetted parts, widened flow passages, and a proprietary sealing system. This ensures long-term, stable operation even in harsh chemical environments.
At Changyu Pump & Valve, we provide reliable corrosion resistant chemical pumps for acid transfer, alkali circulation, corrosive wastewater discharge, electrolyte handling, and chemical slurry transport. Our product line also includes the CYB series corrosion resistant slurry pump and the CYG series high-temperature corrosion resistant pump. Custom designs are available for specialized operating conditions and engineering pump solutions.

Pendahuluan
The UHB series is specifically engineered for transporting strong acids, strong alkalis, organic solvents, and other corrosive media. Its wetted parts are made from imported UHMWPE, formed through a high-temperature sintering process. Optimized flow channels, paired with a proprietary sealing system, reduce the corrosion rate, minimize leakage risk, and maintain stable operation.
Corrosion resistance does not mean total immunity; rather, it ensures chemical compatibility under defined temperature, concentration, and operating conditions. These pumps are widely used in the chemical industry, new energy industry, environmental protection, metallurgy, pharmaceutical, and electroplating industries, where continuous operation and reliability are critical.
Why Standard Industrial Pumps Fail in Corrosive Conditions
The most common issue is improper selection of wetted part materials. Casings, impellers, and shaft sleeves can experience uniform corrosion, pitting, or crevice corrosion, which reduces wall thickness and structural strength, potentially leading to perforation and leakage. Combined corrosion and abrasion accelerate wear, drastically shortening pump service life. How to select overcurrent part plastics can be referenced in material selection articles. 《Chemical Pump Material Selection Guide》
Standard pumps often lack optimized sealing and bearing protection for corrosive media. When corrosive media enter the seal chamber or bearings, it can cause seal failure, bearing damage, and abnormal vibration, leading to unplanned downtime. Corrosion-resistant pump materials and engineering pump design prevent these issues in chemical processing and industrial applications.
Corrosion Resistant Pump Structure Parts and Diagram Show
The main structure of the corrosion-resistant pump consists of core components such as front and rear pump covers, shaft sleeves, seal chambers, bearing assemblies, pump shafts, and impeller nuts. It employs a multi-level sealing and protection design, including skeleton oil seals, water seals, and protective covers, ensuring stable operation under various working conditions. Below is the component breakdown diagram for the UHB model.

Corrosion Resistant Pump Material Selection Guide
Selecting proper wetted part materials is critical for reliability and longevity. Casings, impellers, sleeves, and seals must maintain chemical compatibility under defined temperature, concentration, and operating conditions.
Based on extensive project experience, chemical pump and corrosion resistant pump material selection can be simplified as follows:
| Operating Condition | Recommended Material | Notes |
|---|---|---|
| High abrasion, high solids (>30%) | UHMW-PE | Suitable for corrosion resistant slurry pumps with high wear |
| Low solids, corrosive medium | FEP | Semi-open impeller for balanced flow and corrosion resistance |
| High-temperature corrosive liquid (≥120℃) | PFA | High thermal stability, excellent corrosion resistance |
| High-purity corrosive medium | FEP | Closed impeller design ensures medium purity |
