一、Features: 
1. Interchangeability in connection with other products that meet the requirements of this standard and pump shell, convenient installation and maintenance, shorter axial dimension and less occupation area;
2. Structural design for improving quality -- the pump body adopts the form of high-efficiency volute, whose flange conforms to GB/ t1724.6-1998 pn1.6mpa (16bar);
3. No leakage mechanical seal design -- suitable for occasions where leakage is not allowed, solve the serious leakage problems caused by packing or ceramic seal, ensure the site is clean and tidy, meet the requirements of safety and environmental protection;
4. Direct connecting frame -- the pump and motor are directly connected through the direct connecting frame. The structure is simple and compact, and the concentricity of the components is high.
5. Wide range of flow and head, high efficiency, suitable for all kinds of water supply and drainage conditions, to provide users with the best selection scheme
