1.Conical shaft extension design: when shaft diameter is greater than 60mm, the product uses conical shaft extension design, which is advantageous to installation and disassembly of the coupling, the bearing and the seal .
2.Standard seal configuration:chamber size is completely according to the API682 standard, and it can be configured with multiform seal flushing and cooling plans or configured according to user requirements.
3.Good cavitation performance: suction type impeller, good cavitation performance.
4.Convenient inspection and maintenance: the inner core adopts total extraction structure and can realize the maintenance and inspection of the pump without moving the inlet and outlet pipes.
5.Friction vice configuration: pump body and impeller are provided with seal rings,and its gap and hardness difference are in line with API610 standard. Spare parts replacement is convenient and service life is long.
6.High temperature resistance: at normal temperature, middle seal surface uses "O-type ring";at high temperature, the use of "metal surface VS metal surface" design.
7.Inlet and outlet arrangement form:the normal way is "over-entering and over-out" structure,but also takes other ways according to user requirements .
8.Guide set: the cylinder body is provided with guide key and locating pin. When high temperature medium is transported, the pump extends to non-driving end, and the connection with driving machine is not affected.
9.Balanced structure:Drum-plate-drum balance mechanism effectively avoids "flash" phenomenon, at the same time, greatly improves service life of the bearing and running stability.
10.Reliability assurance:pump body, pump cover and other important parts are manufactured by means of forging process, and 3mm corrosion allowance is guaranteed to ensure pump safety and stability under design pressure.
