Open, single suction type, casted in one piece. All impellers are statically and hydraulically balanced to ensure smooth operation. Back wall of Impeller is provided with ejector vanes following the same curvature of the main vanes of the Impeller which prevents entrance and jamming of solid materials between Impeller and casting wall.
In place of the conventional stuffing box pack-ing, pump can be provided, on order, with mechanical seal. Where mechanical seals are wanted, it is necessary to know all the char-acteristics of the liquid to be pumped, together with the temperature.
When seals are used, a shaft sleeve of AISI 361 stainless steel is recommended in all con-struction to protect the shaft from corrosion inside the box.
