No matter which type of pump is employed, the Lewis Pump user enjoys significant benefits which are the direct result of Lewis' long specialisation in the design and manufacture of equipment for the fertiliser acids industry:

• VERTICAL PUMP CONSTRUCTION CONCEPT eliminates shaft sealing problems generally associated with horizontal pumps requiring a pressurised 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 specialty since 1914.S
• 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.
