Product overview
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 Stage Intellectural Property Office, patent No. is ZL02265708.8 and ZL02316326.7. Meanwhile gain National Key New Products and the certificate of Shanghai Hi-tech achievement transformation authorized by National Science and Technology.
DFSS series pump has stable performance, high-efficiency, easy maintenance, long life and other charecteristics, and is very popular in market.
The design of product is according to the standard of GB/T5657.
Pump adopts linear design and reinforcing rib making the structure more reasonable, beauty outline and installation stable.
Short bearing distance enhances rigidity of shaft, insuring units operate stably, small libration, low noise.
Full closed shaft design, make there is no touch about shaft and medium, to insure shaft no rust, easy dismantle, long life.
Shaft body adopts middle open structure, open pump cover and shaft upper cover, could take out complete rotor, easy adjust and convenient to maintain.
There are two shaft seal structures of mechanical seal and packing seal, according to demand of user, we can adopt special seal mode, such as sand sealing , cut layered packing seal etc.
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.
Pumps select high efficiency hydraulic model and adopt CFD optimal design, enhancing the hydraulic efficiency and improving the performance of cavitation.
Adopt the finite element method for strength calculation, make the pump operate more reliable and durable, extending the life of pump.
Bearing has water cooling structure, can be worked at high temperature. Bearing can select Grease Lubrication of Dilugte oil lubrication.
