Self-priming rubber lobe pump

Rubber lobe pump is a positive displacement pump with self-suction, no one-way valve and flux is proportionate to rotarion speed. Compact structure, convenient assembling, smooth running, low energy cost, high efficiency, small shear force to media, good

Roller-type rotor pump

The roller-type rotor pump is a new rotation displacement pump. It is among the best fluid delivery pumps, consisting chiefly of cavity, rotator and roller. The roller turns closedly against the inner walls of the cavity under the centrifugal and hydrauli
