Profile: Top Level International Industry Co., Ltd. specializes in various CNC machining services. Progressing cavity pumps are used during the normal pumping work, the rotor, stator and some other components would be worn naturally or damaged due to some problems. Then the users need to replace the original spare parts or need some good quality replacement parts instead. We can provide the universal replacement parts with complete models. The rotor and the stator work in pair and matching with each other. The single helix rotor rotates eccentrically within the double helix stator. Then a continuous cavity is formed accordingly and progresses towards the discharge end of the pump as the rotor revolves.
