Double Volute

As the impeller adds energy to the fluid, pressure increases around the periphery of the volute. On single volute pumps, the increasing pressure acts against the impeller and creates unbalanced radial forces. In contrast, Cornell’s high pressure Non-Clogs and Clear Liquid pumps offer a double volute system which effectively balances these forces around the impeller to reduce shaft flexure and fatigue. Cornell’s double volute system eliminates shaft breakage and extends the life of packing and mechanical seals, wear rings and bearings, while maintaining high hydraulic efficiencies.
