DFSS series double suction pump is horizontal single stage double suction pump, which adopts horizontal split. Structure, and gains "Utility model patent certificate" and "Certificate of Design Patent" authorized by State Intellectual Property Office, patent No. is ZL02265708. 8 and ZL0231 6326.7. Meanwhile gain National Key New Products and the certificate of Shanghai Hi-tech achievement transformation authorized by National Science and Technology.

1. DFSS series pump has stable performance, high-efficiency, easy maintenance, long life and other characteristics, and is very popular in market.
2. The design of product is according to the standard of GB/T5657 .
3. Pump adopts linear design and reinforcing rib making the struct ure more reasonable, beauty outline and installation stable.
4. Short bearing distance enhances rigidity of shaft. insuring units operate stably, small libration, low noise.
5. Full closed shaft design, make there is no touch about shaft and medium,to insure shaft no rust, easy dismantle,long life.
6. Shaft body adopts middle open structure, open pump cover and shaf t upper cover, could take out complete rotor, easy adjust and convenient to maintain.
7. There are two shaft sealstructures of mechanicalseal and packingseal,accordingto demand of user, we can adopt special seal mode,such assand sealing.Cutlayered packingsealetc.
8. Pump body and cover both adopt Resin sand molding.which make sure outline of casting and flow passage accuracy dimension.smooth surface, enhancing  hydraulic  efficiency.
9. Pumps select high efficiency hydraulic model and adopt CFD optimal design, enhancing the hydraulic efficiency and improving the performance of cavitation.
10. Adopt the finite element method for strength calculation, make the pump operate morereliable and durable, extending the life of pump.
11. Bearing has water cooling structure, can be worked at high temperature. Bearing can select Grease Lubrication of Dilugte oil lubrication.
