Lewis Sulphuric Acid Pumps

Founded in 1891, Lewis Pumps manufactured its first sulphuric acid pump in 1914, beginning a specialization which has continued to the present time. Today, Lewis is the world's acknowledged leader in the design and manufacture of pumping equipment for sulphur chemistry applications. With material selections featuring the proprietary LEWMET alloys to provide maximum corrosion resistance, the hydraulic and mechanical engineering concepts embodied in Lewis Pumps assure the plant operator of outstanding performance and reliability in high temperature sulphuric acid and oleum. LEWIS VERTICAL PUMPS ARE SAFE FOR YOUR OPERATORS AND SAFE FOR THE ENVIRONMENT. No matter which type of pump is employed, the Lewis Pump user enjoys significant benefits which are the direct result of Lewis' long specialization in the design and manufacture of equipment for the fertilizer acids industry: 
Benefits
VERTICAL PUMP CONSTRUCTION CONCEPT eliminates shaft sealing problems generally associated with horizontal pumps requiring a pressurized stuffing box or seal, ensuring both environmental protection and operator safety.
HEAVY DUTY CONSTRUCTION, required for continuous operation in pumping duties involving high specific gravity liquids, results in smooth, vibration-free operation. In this regard, Lewis' credentials simply cannot be matched by any other manufacturer, as these applications have been a Lewis speciality's since 1914.
SPECIALIZED METALLURGY. Lewis is unique among specialised pump manufacturers in its ability to develop appropriate materials - the LEWMET alloys - which provide our customers with superior material performance in the harsh operating environment of the modern sulphuric acid producing plant.
LEWIS' SPECIALIZATION ASSURES EFFICIENCY AND RELIABILITY. Access to a large number of hydraulic designs enables a close match between user requirements and available liquid ends; in turn Lewis Pumps are assembled from proven standard parts manufactured in large quantity lots - volume production guarantees quality standards are maintained and eliminates design errors resulting from "one of a kind" manufacture.
SIMPLIFIED MAINTENANCE. All Lewis Pumps are designed for simplicity and built with the user in mind. Precision-machined register fits between mating parts eliminate alignment problems - all pumps can be serviced easily using only standard tools of the trade - volume production of replacement parts assures complete interchangeability for even the oldest operating units.
