.R.I. Horizontal multi-stage centrifugal pumps are engineered to perfection with innovative design and stringent quality control to give you trouble free service. These pumps are robust in construction and tested to a high standard of excellence. High grade materials are used to make these pumps durable, efficient and easy to maintain. Shaft is made of high quality steel, precision ground of ample size for transmitting the rated horsepower.

These Horizontal multi-stage centrifugal pumps are of Single Suction, non-self priming type. The impellers are of radial flow design and are balanced to handle hydraulic axial thrust. Based on application multiple outlet ports can be supplied and direction of inlet & outlet ports can be tilted. These pumps are used to transfer clear cold & hot water without solid particles. Also other mediums such as oil, corrosive & abrasive liquids can be pumped by suitably changing the material of construction and sealing type of these pumps.
