 F e a t u r e s

1.  The optimal hydraulic model is used for impeller,the pump is of an utmost dynamic-static balance and reliable performance.
2. The pump shaft is an extended one from the motor,so the concentricity is reliable.
3. The pump which is supported by imported bearing,runs at little vibration and low noise.
4. Single-stage single-suction horizontal centrifugal pump, closed impeller.
5. Coaxial volute structure,high efficiency,small volume lightweight,easy installation and maintenance
6. Mechanical seal,no damage to shaft,no leakage,long duration.
7. Materials can be selected according to the requirement of the customer.
