The suspended parts are fixed onto the intermediate support through the rabbet, and are supported onto the base by suspended frame.

●Easy installation and move, open back structure makes it easy to take out the rotor.

●Discharge on top center, pump body supported by anchor assure the stable structure and maximum resistance off-center and distortion caused by line load.

●No overload design, make sure performance operate stable.

●Adopt national standard hydraulic model make sure high operation efficiency and good anti-cavitation performance.
