產品說明：
       GDD型泵是管道式安裝的立式單級清水離心泵，由於采用了低轉速電機，大幅度降低了運行噪音及振動，延長 了軸承及其易損件的使用壽命。本型泵效率高，己獲得中國節能產品稱號。廣泛應用於工農業給排水、自來水加壓、高層建築生活供水以及中央空調、暖氣循環係統中冷凍水及暖水的輸送。

輸送介質：
稀釋的、清潔的、不腐蝕的、不爆炸的清水及物理 化學性質類似水不含固體顆粒或纖維的液體。

性能及特點:
       采用專門設計製造的低轉速低噪聲電動機驅動，電機和葉輪等轉動部件作了平衡試驗，特別適用於對環境噪音要求高的場 合。該型泵功率在30kW以下的泵的葉輪直接安裝在電機加長軸上37kW以上的泵采用夾式聯抽器與電機連接。拆開泵蓋和葉輪 時不需拆卸吸進和排出管路即可更換密封和葉輪。出水口處於同一軸線上，而且口徑相同，可以象閥門一樣安裝在管路上，安裝方便簡單。

APPLICATIONS
       The type of GDD is the vertical single stage (single suction or double suction) inline centrifugal pumps for clean water. They are coupled with low speed motors, the low speed motor can decrease the operating noise and operating vibration, prolong the lifetime of the bearings and wear parts. This type of pumps are high efficiency pumps, it has obtained title of China energy-saving products.GDD pumps are widely used in industry and agriculture water supply and drainage, water boosting, water supply for high building, central air-conditioning, heating system circulation for cool water or hot water transportation.

APPLICATIONS
The low noise and low speed motors are designed specially, the rotor parts of the motor are balanced, such kind of pumps are suitable for the environment which requires low noise condition. If the power is lower than 30Kw, the impeller of pumps are assembled to the motor shaft, if the power is more than 37Kw, the pumps and motors are connected with clamp couplings. It doesn’t have to remove the inlet and outlet pipeline when dissembling the pump cover and impeller.The inlet and outlet are in the same axis and same diameter. It is like a valve assembling in the pipeline, easy installation.
