Gbw Horizontal Chemical Centrifugal Pump For Concentrated Sulfuric Acid

Horizontal chemical centrifugal pump engineered for safe, reliable transfer of concentrated sulfuric acid (80–98% concentration). Built to IS-series hydraulic performance parameters, this GBW horizontal pump is available in two construction materials—special carbon steel and special cast iron—selected to match service temperature and corrosion-resistance requirements.

Key features

• Designed for concentrated sulfuric acid service (80%–98%).
• Material options: special carbon steel (recommended for temperatures up to 60°C) and special cast iron (recommended for temperatures up to 50°C).
• Horizontal, single-stage centrifugal configuration with optimized impeller profile for efficient hydraulic performance.
• Shaft sealing: externally mounted mechanical seal with dynamic and static rings in hard alloy or ceramic for excellent wear resistance, long life and minimal leakage.
• Performance range: flow 4–550 m3/h, head 12.5–50 m, selectable rotational speeds 1,450 or 2,900 rpm, power 1.1–55 kW.
• Model numbering example: GBW 25-125 — “GB” indicates concentrated sulfuric acid pump, “W” indicates horizontal, “25” = inlet/outlet diameter (mm), “125” = impeller diameter (mm).

Typical applications

• Chemical process plants handling concentrated sulfuric acid
• Acid storage and transfer systems
• Industrial facilities requiring corrosion-resistant pumping of strong acids

Selection notes

• Choose the carbon-steel version for higher-temperature acid service (up to 60°C) or where higher mechanical strength is required; choose cast-iron where lower temperature limits and cost considerations permit (up to 50°C).
• Specify required flow, head, liquid temperature and concentration, and preferred shaft seal material (hard alloy or ceramic rings) so the pump and mechanical seal can be selected and sized appropriately.
