MB / General VTP centrifugal pumps in block design (BBF) correspond to the system of two-pipe pumps. Basically these immersion pumps are single-level immersion pumps with vertical axis the main components of which are combined according to the proven module system. The drive motor is located in the dry section above the fastening plate. The pump head is immersed in the medium. VTP-BBF immersion pumps are designed without bearings and are suited to convey low-viscosity, aggressive acidic, alkaline and solutions from depressurized tanks. The efficient immersion depth can be increased by max. 3 mm by using a suction pipe. Furthermore the pump head can be equipped with a coarse at the suction connector. Constructional features VTP-BBF immersion pumps are characterized by their simple and sturdy design. The immersion pipe is fitted with a rigid supporting plate and thick sides. The sealing between spiral casing and immersion pipe is realized by a labyrinth seal. The hydraulic parts such as spiral casing, impeller, etc. are standard components from the standard pump program. The drive motor (basic version according to IEC) is equipped with an extended shaft. Therefore it is not necessary to provide the shaft with a bearing in the pump head area so that dry running is prevented and operation is almost maintenance-free. Applications There is a variety of possibilities to use vertical immersion pipes. They are generally suitable for applications which do not allow to convey the media from depressurized tanks, basins and reservoirs with dry pumps due to the local constructional, physical or safety requirements. The maximum operating temperature depends on the concentration of the medium, a temperature of 8 C must, however, not be exceeded for the material PP. Materials All parts in contact with the medium are made of PP, elastomers are of EPDM or FPM. Shaft The drive shaft of high-quality steel is coated with a PP shaft protection pipe in the area of the medium. Impeller The impeller form is radial. The individual sizes are supplied with the following impellers: sizes -8, - and -3 in open form, all other sizes in closed form (open impellers on request). Inlet and outlet pipe connection The suction opening is located in the lower section of the pump, i.e.: the medium enters the pump body axially. The outlet pipe connection is situated in the dry section above the tank cover. Drive Surface-cooled three-phase motors according to IEC standard, 9 rpm, protection class IP, insulation class F, mounting IM V. The motor has an exended shaft.
