1 Type series booklet.5/80 G KWP KWP nonclogging centrifugal pump Automation products available: PumpEpert Hyamaster hyatronic Fields of Application For handling all kinds of pulps not liable to plait, as well as stock suspensions up to 5 % bone dry. This pump is used in the chemical and process engineering industries, paper and pulp industries, sugar, food and beverages industries, in flue gas desulphurisation and coal upgrading and in the treatment of industrial effluents. Design Horizontal, radially split volute casing pump in back pullout design, with impeller adapted to meet application requirements, singleflow, singlestage. Special Features Reinforced, aially adjustable bearing assembly on all pumps Shaft seal: mechanical seal integrated into the casing cover, or gland packing Even cast iron pumps are supplied with pump internals (impeller and wear plate) made of wearresistant ERN (nickel cast iron) Certification Certified quality management ISO 900.

4 Design Features Flange design in accordance with DIN/EN up to PN ; other flange designs are possible. Shaft not in contact with the medium handled (dry shaft); therefore no special materials required. Back vanes for reduced aial thrust and shaft seal balancing. All mechanical seals integrated in the casing cover with conical seal chamber (Atype cover), therefore improved internal circulation, automatic venting and deadend operation possible. Rotor and bearings are dimensioned for a shaft deflection at the shaft seal below 0.05 mm and a bearing life of more than 7 operating hours. On request, pump casing is available with inspection hole. Reinforced adjustable bearing assembly. Safe design of all pressureretaining components due to quality casting with corrosion/wear allowance. High efficiencies in the case of channeltype impeller design; impeller with front vanes and diagonal gap. Pump casing with suctionside wear plate in wearresistant diagonal gap design. Due to the back pullout design, the casing may remain in the pipeline when the pump is dismantled. Rigid and stable support foot ensures that even in the case of high eternal forces the shaft is only slightly displaced in the coupling area. Pump version with gland packing and special discharge cover. Jacking screws facilitate dismantling. Use of eisting modular design components ensures small stock of spare parts and fast delivery. Cylindrical roller bearing as movable bearing permits easy assembly and compensates possible thermal epansion of the shaft. Constantlevel oiler ensures constant lubrication of the bearings.
