DG series centrifugal pump is applicable for conveying liquid without solid particles, corrosive liquid, clear water at 105 °C or liquid with physicochemical properties similar to clear water, suitable for small boiler water supply or conveying hot water or media similar to hot water.
This machine is a horizontal, single-suction multi-stage, segmented centrifugal pump, the pump casing can be dismantled in the axis. The pump body is composed of inlet section, middle section, outlet section and so on, and each department is fastened together by bolts, this structure is convenient for manufacture, installation and maintenance, and also can ensure the working strength and sealing of this pump. The impeller of this pump also adopts the patented balancing technology, which removes the failure-prone balancing device, reduces the accidents of broken shaft, holding and destroying the motor, improves the operational reliability of the pump, and further enhances the efficiency of the pump. In addition, the structure of DG series hot water centrifugal pump is well-designed, which reduces the number of wearing parts, prolongs the maintenance cycle and lowers the maintenance cost.
DG series centrifugal boiler feed pump has a wide range of performance, with a flow range of 6.3-450 m³/h and a head range of 75-600m, which can meet the requirements of use under different working conditions. Adopting energy-saving and efficient hydraulic model, the efficiency is about 3% higher than that of ordinary centrifugal pumps, and the energy-saving effect is obvious. The pump has low necessary cavitation margin and good anti-cavitation performance, which can effectively prevent the pump from being damaged by cavitation during operation. At the same time, in order to ensure the stable operation of the DG series centrifugal pump, the rotor parts with good performance are used to reduce the chances of mutual friction, and the vibration is small and the noise is low during the movement.
In order to use different media conveying requirements, the pump's main use of high-quality wear-resistant parts, can also be used according to the different media theme or stainless steel and other corrosion-resistant materials to extend the service life of the pump. Therefore, DG series centrifugal water pump can be widely used in mines, factories, city water supply, high-rise buildings, water treatment, industrial and agricultural production, HVAC and other fields. DG series centrifugal pumps produced by our company are subjected to strict quality testing and experiments, and running, mechanical, cavitation, noise and other tests are carried out before leaving the factory to ensure the reliable quality of the products.
