GNF pumps single-impeller centrifugal pumps are designed to achieve high delivery rates with low to average heads. The impeller, mounted on the end of the drive shaft, faces directly the suction opening machined in the pump body. The shape of the impeller is designed, with minimal hydraulic loss, to impart radial motion from the center outwards. During this operation the blades inside the impeller channel transfer energy to the fluid both in the form of pressure and increased speed. The fluid that leaves the impeller is conveyed into the volute, together with the cone diffuser, transforms part of the kinetic energy into pressure energy.
