The DuraCirc Pump construction features two rotors, housed within a pumping chamber, known as a rotorcase, with each rotor located on a shaft held rigidly within a gearcase. The two rotors are timed via timing gears in the gearcase, which along with shimming, ensures no rotor or rotor case contact. Rotor/shaft drive is typically provided via geared electric motor.
Due to the close internal running clearance within the pumping chamber, the rotation of the rotors continuously generates a partial vacuum in the suction port of the pump as the rotors unmesh. This results in a localized pressure drop, which allows fluid to enter the pump. The fluid is then transported around the channel by the rotor wings and the pressure generated as the rotor wings re-mash forces the fluid out of the discharge port of the pump.
Duracirc Pump Working principle
The rotor pistons rotate around the circumference of the channel in the Duracirc Pump casing. This continuously generates a partial vacuum at the suction port as the rotors unmesh, causing fluid to enter the pump. The fluid is transported around the channel by the rotor pistons, and is displaced as the rotor pistons re-mesh, generating pressure at the discharge port. The direction of the flow is reversible.
