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, Weir Minerals Lewis Pumps' credentials simply cannot be matched by any other manufacturer, as these applications have been a Lewis speciality 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 vertical acid 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
