1.Product Desciption:
Model TRA universal cam and rotor transfer pump (without coupling)
2.Working principle:
Operating principle
The TRA Lobe pumps basically consist of two lobe rotors which rotate synchronously inside a casing without touching each other.The two rotors divide the rotor chamber into to several smaller rooms and move in order as: a→b→c→d. At position a, only room Ⅰif filled with medium; at position b, some medium is closed in room B; at position C, some medium is also closed in room A, and at position d, room A and B are connected with room Ⅱ; here the medium is delivered to the outlet. With this circulation, the medium (material) is delivered through the pump continuously.
3.Technical parameters:
As the rotors rotate, the spaces between the lobes and the casing are successively filled with fluid, which is transported to the discharge nozzle with a fixed amount of displacement. The pumped fluid forms a continuous stream thanks to the tolerances between the lobes and the pump casing, thus ensuring an efficient pumping.
