Centrifugal Vertical Pumps

Design BRJGHAAaaLEDB T K The coupling V series pumps with vertical shaft comprise two mainparts: Ε The first one consisting of an assembly in impregna-ted graphite (GRAPHILOR (J) is supplied bored and grooved, pro-vided that you accept our standard motor (see chapter "information required to order a pump"). Two plates (T) enable the assembly of the pumps on anadequate frame. The bearing frame (G) holds two opposite conical ballbearings.This design allows absorption of important axial pressures (for example with liquid with a high spe- cific weight).Oil lubrication of the bearing is made by two Tecalemit lubricators.The time between two lubri- cation operations should be moderate e.g. approx. 5000hours. Materials on the shaft. Leakages, theflow rate of which is reduced by countervanes, travel up the shaft, then are collected in the bleedbox(D), pushed back by a deflector(E) and finally driven back to the tank by an adequate piping. > do notinclude any tightness seal ) building the hydraulicpart.Ε The second one consisting of a metallic assemblycomprising the rotating shaft (H), a bearing frame(G) and a coupling (J). All the pieces in contact with the pumped fluid aremade in GRAPHILOR (impregnated graphite resisting to most corrosive fluids). The bearing frame is in cast iron and the other metal- lic parts are in steel. All metallic parts are protected outside by an anti- corrosion paint. The joints are in IT (CAF: rubberised asbestos) anti- acid quality or in ethylene-propylene. The "GRAPHILOR" assembly is supported by tie rodsequipped with spring washers which ensure a constant compression between assembly plates (L) and (K). The front clearance (between the body and the vanes of the impeller) can be adjusted by adding or remo- ving the shims (AA).

We can supply GRAPHILOR filters (mesh approx. 4mm)which have the advantage of being easily dis-mantled and cleaned (as drawing 50076).Motor: other motor type than...
