Impellers

Presto Chemtech offers Impellers. Advantages: designs based on process requirements and vast experience; imparts efficient mixing at lower power consumption; ensures better process solutions; low cost for new reactors as lower size of gearbox and motor and substantial savings in capital cost of agitator assembly; and easy to replace in the existing system. Super impellers for industrial agitators are designed based on process parameters and bulk fluid velocity ensuring better process solution at lower power consumption. Standard SA310 range of super impellers provides axial flow for the liquid movement with less radial and rotational flow than standard pitched blade turbines, flat blade turbines and paddles. Flow pattern: in fluid agitation the direction as well as the magnitude of the velocity is important. The flow of SA310 super impeller is primarily the axial type. This flow pattern is significant as it imparts very low power consumption while improving the pumping of liquid. It also sweeps solid suspension off the reactor bottom. In case of conventional impellers, vortex is generated on the trailing edges of the blades, which in turn causes drag. The improved blade profile of the super impeller reduces the vortex generation on the trailing edges of the blades and hence reduces the drag. Super impellers provide maximum pumping capacity with reduced energy dissipation. These are available in any metallic construction. Substantial savings in capital investment is obtained due to lower size of gearbox and motor, and reduction in shaft diameter.
