Product Overview
GBL Vertical Sulfuric Acid Chemical Pump
GBL Vertical Sulfuric Acid Chemical Pump is a single-stage vertical centrifugal pump specifically designed for concentrated sulfuric acid transfer in chemical process systems.
It addresses rapid corrosion failure of conventional metal pumps, seal leakage risks, and structural instability under high-density acid conditions.
It is suitable for sulfuric acid circulation, acid storage tank discharge, fertilizer process transfer, and sulfuric acid production lines.
