Rotary pumps are used to pump liquids such as oil and other viscous fluids. They are used to manage fuel oils, lube oils, and a broad variety of liquids. These pumps have small clearances between stationary parts and rotating parts to reduce leakage from discharge side back to the suction side. It is designed to work at comparatively at low speeds to maintain these clearances. Operating these pumps at a higher speed can cause excessive wear and erosion, which can increase clearances with a subsequent decrease in pumping capacity. Expansion of the wastewater management and water recycling industries and rise in investment in the non-oil sector are estimated to drive the rotary pump market during the forecast period. Furthermore, benefits offered by new products such as advanced treatment solutions and gear pumps are projected to boost the market. Advanced feature of rotary pumps such as their ability to transport harmful chemicals without damaging the environment is a key driver of the...
