Structural characteristics :
1.The distance between the two ends of the pump is short, the pump runs stably, the vibration noise is small, and the pump can run at an appropriate speed to make the pump adapt to a wider range.
2.The inlet and outlet are on the same straight line, which makes the pipeline layout simple, convenient and beautiful.
3.The same rotor can run in reverse, which reduces the risk of pump damage caused by water hammer.
4.Unique high temperature design, the pump adopts intermediate support, thickening pump body, sealing cooling, bearing thin oil lubrication, etc., so that the pump can be applied to the operation of up to 200 °C, especially suitable for heating pipe network requirements.
5.The pump body can be installed vertically or horizontally according to the change of working conditions, and the seal can be mechanical seal or packing seal.
6.water pump appearance application of industrial design, clear lines, in line with modern aesthetics.
7.The excellent hydraulic model is used to make the efficiency of the pump 2-3 % higher than that of the same type of pump, which greatly reduces the operating cost of the pump.
8.The necessary NPSH is reduced by 1-3 meters, thereby reducing civil construction investment and extending service life.
9.The selection of imported bearings, parts and materials can be selected according to user application requirements, so that the pump can adapt to various field operating conditions, greatly reducing the maintenance cost.
10.No adjustment mechanical seal, replace the mechanical seal to become easy and simple work.
11. The application of elastic prestressed design assembly, rotor parts assembly and disassembly is simple and rapid.
12.There is no need to adjust various gaps during assembly.
