Fire fighting pipeline pressurizing;
Cold and hot water circulation in air-condition;
Transport water from far away;
Pressurizing transport in industrial circulating system, and all kinds of water supply equipments, boiler etc.
DFG series (pipe hot water is derived from this type) are designed carefully according to different working conditions. The hydraulic model is excellent. Product quality of the implementation of GB/T 5657-1995" Centrifugal Pump
condition classIII standare".
The motor and pump are joined directly without transmission parts. So they operate smoothly. The inlet and outlet can be fixed anywhere like valves in pupeline. Compared with common horizontal pump, DFG series can decrease 30 percent floor space. Besides, they feature smooth operation and lower noise etc. The life of damageable parts is prolonged. In conclusion, this series pumps are favored in market because of their smooth operation, high efficiency, less energy consumption, small floor space and compact structure.

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;
Ordering, no special requirements to flanges book list data delivery, if any special requests when ordering;
State seal flushing method: wash the external and external washing. Add the rinse water temperature is suitable for =80°C or media containing sand and other particles of the occasion;
Flat flange of the pump, with the sealing surface for sealing wire required the contract specified.
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.
