Centrifugal Water Pump INTERSIGMA L-V Series L-VA4-D , L-VN4-D , L-VN5-D-01
]Centrifugal Pump INTERSIGMA L-V Series The pumps are of centrifugal, multistage design, with radial flow impellers and horizontal axis. They consist of a rotor and a stator with bearings and stuffing boxes.
THE STATOR of the water pump is assembled from stage casings sealed with rubber sealing rings and clamped between the suction and the discharge bodies into one integral subassembly by means of clamping bolts which are arranged outside the pump body. The pump stands on foots which are situated on stage casings. Because the suction body has no foots it is possible to turn it at different arrangements.THE ROTOR of the water pump consists of shaft and of one-sided inlet impellers which are fixed with keys and tightened by means of bushes with nuts.The shaft is supported on ball bearings at both sides. Driven end of the shaft is taken out at discharge side of the pump. There are balancing holes in impellers to equalise (partly) the hydraulic axial force of the rotor. The remaining part of the axial force is taken up with bearings. The complete rotor is statically balanced so that smooth operation of the pump is ensured.THE STUFFING BOX of the pump is gland packing type. Quality of gland packing cord is chosen according to properties of pumped liquid.
