6. Our advantage 

6.1  High & better self-priming performance: 

Suction head up to 9.5 m
Synchronous Dry priming
The suction head is more better than normal self-priming pump

6.2. Quick start and restart: 
No need feeding water before first start . 
Reduce the site work

6.3. Efficiency ≥80%, save running cost,   Energy-efficient in all pump life. 

6.4. Passing the solid particles up to 85 mm, sensible choice under various working condition. 
Due to pass the large diameter solid particles, so this SD series pumps are suitable for deep. 

6.5. Flange standard: GB, HG, DIN, ANSI standard, according to your requirements. 

6.6. Various materials to choose
Cast iron/ stainless steel/ steel/ Ductile iron/ Duplex stainless steel
Shaft seal: Mechanical seal 

6.7. Save installation place, low noise, easy maintenance
Compact structure, SD series High efficiency energy-saving self priming centrifugal pump. Pump casing and the suction device is compact; Save the installation place. The pump running with stable operation, and low noise. The pump assembly by the high concentricity components.
