Convex pumps are designed to market an advanced technology in hard to pump fields. In the applications where pumping by centrifugal, progressive cavity or other type of pumps involves high life cycle costs (LCC), Convex pumps are the right solution. The fluid to be pumped rotates inside the casing through an innovative impeller which, thanks to its design unique and to fluid viscosity, generates a powerful vortex. The open design of the impeller and the absence of close tolerances eliminates blockage and wear problems, produces a smooth pump operation, pulsation-free and without product damage. Several are the benefits of Convex compared to conventional pumps especially in the process of industries handling abrasive, viscous/delicate fluids, sludge, liquids with entrained air / gas, slurries with high solids content and shear sensitive materials. In these applications Convex pump cuts maintenance costs, reduces spare parts inventory, increases process efficiency and productivity with fast pay back.
