WORKING PRINCIPLE:

TGA pumps are centrifugal pumps with an open impeller. The impeller, mounted on the end of the motor shaft, consists of a back disk and blade. The design uses the pump body to delimit the blade channel, rather than a front counter disk , as with closed impeller pumps. The blade channel therefore consists of a rotating part (back disk and blades) and of fixed part (pump body): this form of construction avoids the possibility of clogging even when handling fluids with fairly large amounts of impurities. The fluid enters the rotating blade channel via the suction opening, which faces the center of the impeller. From here the fluids is accelerated by the impeller from the center outward, acquiring energy from the blades in the form of pressure and an increase in speed. When the fluid leaves the impeller it passes around the pump volute and is guided out of the top delivery opening, under pressure, by the diffuser.
