Lewis Phosphoric Acid Pumps

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.
SPECIALIZED METALLURGY. We have the capability, believed to be unique among specialized pump manufacturers, to select the appropriate metallurgy both from commercially available materials and from our own proprietary alloys. This capability assures the user of unmatched material performance in the harshest operating environments.
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.

Lewis axial flow pumps,constructed from proprietary alloys and with a robust mechanical end, provide excellent service for phosphoric acid manufacture or other chemical processes that utilize high volume low handling recirculation loops. 
 
As a metallurgically-based manufacturer of pumps used in the production of fertilizer acids, Lewis first began developing alloys for P2O5 service in 1957. Today, Lewis can select from a wide range of materials for your phosphoric acid pump, including both commercially available alloys as well as the proprietary LEWMET alloys which have been specifically designed to provide maximum performance in acids containing high levels of fluorine and chlorine. Both austenitic alloys, providing the highest degree of corrosion resistance, and duplex alloys, exhibiting the more abrasive environments, are available. LEWIS HAS THE CORRECT ALLOY SELECTION TO SUIT YOUR SPECIFIC PHOSPHORIC ACID PUMP APPLICATION. 
Benefits
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:
