Over 40 Years ago, Ram Ratan Gupta, a coal mine owner, was using a  battery of progressive cavity  pumps in his mines for face dewatering application. While he was intrigued by the complex profile of the rotor but at the same time he was frustrated by the recurring problems faced in importing spares for the pumps. He was aware that the entire Indian mining industry was confronted by this problem.

He set his mind to manufacture these pumps indigenously but he did not have access  to the technical know-how,as the process of manufacturing complex-profile rotor was closely guarded by few overseas manufacturers.

Gupta’s dedication, determination and technical ingenuity, led to  success. Soon, he invented a unique manufacturing (generating) process for machining the complex profile of the rotor. His technique was amazingly effective and did not demand huge investment. News of the break through reached the mining community, who turned to him to source these critical spares. The transition from manufacturing vital components to complete pump was a logical step and thus, Roto Pump was born.

Continuous investments in precision measuring instruments, state-of-the-art testing facility and a dedicated team of engineers are testimony to Roto's commitment to maintain and constantly upgrade the quality of its products. The manufacturing units are certified for conformance to the ISO 9001-2000 quality surveillance systems.
