VMB Series Vertical Single Suction Multistage Centrifugal Pump
VMB vertical single suction multistage centrifugal pump suitable for high-rise buildings of domestic water supply, fire water supply, pressurization and boiler water supply and othet occasions. The series of pumps are characterized by small filowhigh head, high efficiency, low noise, small floor area, strongreliability, easy installation and maintenance, and low operating cost.
Pump body-VMB vertical single suction multistage centrifugal pump pump body design for 40kq/cm2. Its material has gray cast iron, nodular cast iron, stainless steel and so on.
In order to meet the different requirements of users worldwide, the corresponding pump body inlet and outlet flanges can be selected according to ANSI, PN and JIS standards Vmb-type vertical single suction multi-stage centrifugal pump impeller all cast stainless steel impeller, impeller and shaft usino the key link to achieve efficient and stable transmission.
Guide VMB vertical single suction multistage centrifugal pump USES quide vane design to balance radial force.
Balance drum VMB type vertical single suction multistage centrifugal pump adopts balance drum structure to realize the balance of axial force, which reduces the load of shaft bearing to the maximum extent and thus prolongs the service life of bearing.
Bearing a VMB vertical single suction multistage centrifugal pump bearing its standard confiquration for grease lubricated angular contact ball bearings, according to user demand, car also use thin oil lubricated bearings. Water bearing (including inlet bearing and intermediate bearing) has ptfe, silicon carbide, tungsten carbide and other materials for users to choose, toensure the best running time, thus reducing the running cost The bearing in the inlet section is mounted on a movablebearing seat for easy maintenance without removing other parts.
Shaft and bearing -pump shaft and shaft sleeve are available incarbon steel, stainless steel, duplex steel and other materials.
The shaft sleeve is replaceable to protect the pump shaft from wear and tear, thus reducing maintenance costs.
Seal a VMB vertical single suction multistage centrifugal pump can be used either packing seal or mechanical seal, when the use of mechanical seal, can be in the case of no need to remove the pump mechanical seal replacement.
Import and export a VMB type vertical single-suctior multi-stage centrifugal pump for the radial suction, radia discharge, import and export of relative installation directior can be adjusted according to user needs to 0°and 90°, 180°，
270°, VMB type vertical single-suction multi-stage centrifuga pump export, also can set up multiple users can be equipped with only a single pump, under the condition of differen pressure output, in order to meet the different pressure in the system.
