Roto Pumps North America Inc.
About
Roto Pumps North America Inc. (RPNA), established in 2014 as a wholly owned subsidiary of Roto Pumps Ltd. of India, manufactures from Tulsa, Oklahoma and maintains a corporate office in Fort Mill, South Carolina. Operating under the ROTO ULTRA brand, RPNA is recognized among the top ten global manufacturers of positive displacement pumps and markets products built on over 50 years of parent-company engineering experience. The progressive cavity pump lineup includes more than a dozen configurations: the Standard PC Pump for general sludge and effluent transfer, the ROTO KWIK (MIP) for quick-strip maintenance access, Aggressive Chemical Dosing Pumps for corrosive service, Flexible Shaft Series pumps for extended-coupling installations, Wide Throat Pumps for high-viscosity sludges and dewatered cake, Submerged Pumps for wet-well and sump applications, Food Pumps with sanitary CIP design, Vertical Pumps for pit installations, Biomix Pumps for anaerobic digester mixing, Biomass Pumps for thick organic waste transfer, and Drop-In Pumps with wobble-stator design for lift station retrofits. Beyond PC technology, RPNA manufactures twin screw pumps in horizontal internal bearing, horizontal external bearing, and vertical configurations for high-flow lubricant and fuel transfer, Roto Artificial Lift downhole PC systems for oil and gas production, and the Roto Mining Station for mine dewatering. A proprietary Wear Compensation Stator adjusts for internal wear to maintain pump performance and extend service intervals. The company's online Pump Selector maps over 30 fluid types to recommended pump models across 24 industries, with particular wastewater depth covering activated sludge, thickened sludge, polymer dosing, chemical dosing, and dewatered cake transfer. RPNA holds ISO 9001, ISO 14001, and OHSAS 18001 certifications.
