11.采用了加長撓性膜片式聯(lián)軸器部件，檢修時不必拆卸吸入和吐出管路就能拆出葉輪、軸等零部件；
12.對軸承、泵支架，根據(jù)工況條件進行冷卻，冷卻水的管路布置符合API682規(guī)范。
13.泵和電機安裝在同一個公用底座上。
14.法蘭標(biāo)準(zhǔn)可提供ANSI、HG/T20615、HG/T20592等多種選擇。
15.可配帶普通電機、防爆電機、直流電機和永磁電機等。
1. This seriespumps are all single stage, single suction, horizontal cantilever centrifugalpumps.
2. These pumps adopt axial horizontal suction and radialvertical discharge.
3. Pump bodyadopts volute type, radial splitting, and horizontal central support.
4. The impeller is an integral casting, complete with rear sealring and balance hole to balance axial force.
5. Eddy flow heat and friction heat generated in the pump istaken away by various circulation modes, e.g. pumped process liquidself-circulation and forced circulation of externally connected liquid, tosatisfy conveying of media under different operating conditions.
6. Cooling or thermal insulation jacket can be provided ifrequired by operating condition such as crystallization or evaporation.
7. Optimized rigid shaft structural design provides betterdeflection index, further reducing pump vibration.
8. Internal sliding bearing adopts thick, heavy duty, strongthrust ceramic bearing, and high purity, high wear resistance silicon carbide material,thus allowing long service life.
