Lewis Pumps Suppliers & Distributors in UAE

Transferring concentrated sulphuric acid, oleum, and molten sulfur at elevated process temperatures requires specialized pumping hardware engineered from proprietary erosion-corrosion resistant alloys. Standard stainless steels degrade rapidly in hot acid environments, risking catastrophic chemical release and severe plant downtime. Chemical manufacturing facilities, industrial fertilizer plants, and gas sweetening operations across Abu Dhabi and Dubai rely on robust vertical cantilever pumps and acid gate valves to maintain continuous, leak-free liquid transfer under demanding thermal regimes.

About Lewis Pumps

Lewis Pumps, operating as a specialized operating unit within Weir Minerals, represents the global standard in heavy chemical process pumps and severe-service valves tailored for concentrated sulphuric acid, oleum, and molten sulfur service. Tracing its engineering origins back to 1891, the brand designed the world's first dedicated sulphuric acid pump in 1914. To overcome the extreme erosion-corrosion mechanisms inherent in high-temperature mineral acids, the company developed Lewmet, a proprietary family of advanced nickel-chrome and austenitic specialty alloys engineered to withstand severe chemical degradation.

Unlike conventional centrifugal pumps that experience rapid impeller wear and shaft seal degradation in acid circuits, these vertical process pumps incorporate cantilevered shaft geometry and hydraulic designs specifically optimized for acid cooling towers, sulfur melting pits, and leaching operations. The brand supplies major chemical processing plants and acid regeneration facilities worldwide with pump systems that maximize process availability and operational safety.

Lewis Pumps product range

The specialized product line encompasses heavy-duty vertical and horizontal pumping solutions engineered for aggressive acid and sulfur applications:

• Vertical Sulphuric Acid Pumps: Heavy-duty vertical cantilever chemical pumps constructed from proprietary Lewmet alloys, featuring long shaft overhangs and zero submerged bearings to handle concentrated acid up to ninety-eight percent.
• Vertical Molten Sulfur Pumps: Thermally jacketed vertical immersion pumps designed with internal steam tracing to maintain molten sulfur fluidity and prevent freezing during high-temperature transfer.
• Lewmet Specialty Acid Gate Valves: Severe-service shutoff valves manufactured with Lewmet body castings and seating faces, providing tight isolation against hot, aggressive sulphuric acid streams.
• Axial Flow and Low-Head Acid Circulators: High-volume axial flow pumps engineered for acid cooling towers and evaporator circulation loops requiring massive volumetric transfer at low dynamic heads.
• Lewmet Replacement Impellers and Wear Parts: Precision-machined impellers, casings, shaft sleeves, and throttle bushings designed to restore factory hydraulic tolerances in corrosive process loops.

Industries & applications in UAE

Chemical processing plants, sulfur granulation terminals, and energy processing complexes across Abu Dhabi, Ruwais, and Jebel Ali require rugged process pumping infrastructure to handle severe chemical duty. At major sour gas processing facilities in Ruwais and Habshan, sulfur recovery units (SRU) utilize vertical molten sulfur pumps to transfer liquid sulfur from condensing vessels into granulators and export holding tanks.

In fertilizer synthesis operations and chemical manufacturing facilities across KEZAD and Dubai Industrial City, vertical acid pumps circulate ninety-eight percent sulphuric acid through drying and absorption towers where standard pumps would fail within weeks. Furthermore, industrial water treatment plants and acid regeneration units deploy Lewmet acid gate valves to ensure safe, positive isolation during scheduled maintenance turnarounds.

Sourcing Lewis Pumps in UAE

Procuring genuine process pumps, valves, and precision Lewmet replacement castings across the United Arab Emirates involves engaging with authorized Weir Minerals regional representatives and specialized industrial pump distributors. Local engineering partners maintain technical support teams capable of reviewing hydraulic flow sheets, calculating Net Positive Suction Head (NPSH) requirements, and recommending optimal alloy grades for specific acid concentration profiles.

Authorized stockists based in Abu Dhabi and Dubai provide genuine OEM replacement impellers, casing liners, shaft assemblies, and mechanical seal flush components to support emergency plant maintenance. When requesting technical proposals, plant engineers should submit exact chemical concentrations, operating temperatures, specific gravity, and pipe head parameters.
