Mr. Gupta created history in 1968 by inventing a unique manufacturing process for machining the intricate profile rotor, which is the heart of progressive cavity pump. This technological innovation gave birth to Roto Pumps... Mr. Gupta strongly believed in "in-house" development of products and manufacturing technology as opposed to importing technology. This philosophy translated into continuous investment in Research and Development as well as in manufacturing infrastructure, enabling Roto Pumps to produce quality products at a competitive cost.
