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.

Ordering instructions
Must provide order information: 

The required pump model or user operating point flow, head, NPSH, the nature of the medium and temperature parameters and special parameters of the basic requirement; 
The pump main parts material (not to specify the configuration according to the sample delivery); 
Inlet pressure (if inlet pressure >=0.6MPa, pump casing should equip with high strength material); 
The shaft seal type (three are mechanical seal, injectable soft-fillings seal, special seal part, packing seal and so on, it will delivery packing seal if it does not indicate); 
The bearing structure type (select according to medium temperature and so on, it will deliver standard fitting if it does not indicate); 
Revolving direction of pump (view from the end of transmission, the revolving direction of pump is anticlockwise. It will deliver standard fitting if it does not indicate); 
Motor rotational speed, power, voltage, protection rank, insulation grade, cooling method, whether to guard against explosions and so on; 
Base: the sample 315 with the following common base frame sizes, frame sizes above 315 with a split base or no base, please specify when ordering; 
For spare parts, please indicate the name and quantity of spare parts required;

Selecting description: 

The order of user isn't limited by the data which listed in the sample performance curve and performance parameter chart, this company may design and provide the products specially according to user's actual requirement flow and head; 
If it is close to the listed performance parameter, it will prefer to select the standard impeller pump and the high speed pump generally (the premise is that satisfies the requirement of cavitation performance); 
If user's required flow and head parameter aren't in the scope of product's large flow and low head operating condition, the matched motor power may confirm and reduce properly according to the actual operating condition point. 
if you have special selecting or have the unclear place to the sample, please inquire the technical support department of Shanghai East Pump (Group) Co., Ltd directly. 
Recommended spare parts: shaft, mechanical seal, seal ring, packing, bearings, impeller.
