La bomba extractora está compuesta de una carcasa exterior o estator, que aloja al rotor, estando el eje de giro del rotor desplazado respecto al eje del estator.The extractor pump is composed of a outer shell or stator, which houses the rotor, with the axis of Rotation of the rotor displaced with respect to the stator axis.

El rotor presenta unas paletas, que poseen posibilidad de desplazamiento en dirección radial y que a instancia de su roce con las paredes internas del estator y el giro del rotor se produce el deslizamiento de las mismas para adaptarse a la pared interna de estator.The rotor has vanes, which have possibility of displacement in radial direction and that upon request of its friction with the internal walls of the stator and the rotation of the rotor the sliding of the same takes place to adapt to the wall internal stator.

Las paletas diametralmente opuestas del rotor de la invención preconizada constituyen una única pieza que atraviesa el rotor diametralmente, pudiendo desplazarse en el interior del mismo. Para posibilitar el desplazamiento relativo entre paletas, ya que éstas al atravesar diametralmente el rotor se cruzan en el eje de giro del rotor, una de ellas debe presentar un cajeado de inserción del resto de los pares de paletas.The diametrically opposed vanes of the rotor of  the recommended invention constitutes a single piece that crosses the rotor diametrically, being able to move inside the same. To enable relative displacement between pallets, already that these diametrically cross the rotor intersect on the shaft of rotation of the rotor, one of them must present a recess of insertion of the rest of the pairs of vanes.

La pared interna del estator presenta un perfil circular achatado en su parte superior e inferior y simétrico respecto de un eje vertical que pase por los ejes de giro de rotor y el eje del estator. El perfil interno del estator está engendrado por los extremos de una recta de longitud igual a la longitud de las paletas girando con eje de giro el del rotor y de manera que el perfil resultante sea simétrico.The internal wall of the stator has a profile circular flat on top and bottom and symmetrical with respect to a vertical axis that passes through the rotor rotation axes and the stator shaft. The internal stator profile is generated by the ends of a line of length equal to the length of the vanes rotating with rotation axis the rotor and so that the resulting profile be symmetric.

El rotor es un cuerpo cilíndrico hueco que se encuentra atravesado diametralmente por un número par de paletas, disponiendo para ello de ranurados radiales de inserción de las mismas. Consta en sus extremos de unas abrazaderas que vinculan las distintas secciones en las que quedaría dividido el rotor por efecto de las paletas pasantes. El rotor cuenta también con una serie de cajeados simétricamente distribuidas de alivio de su peso.The rotor is a hollow cylindrical body that found diametrically traversed by an even number of pallets, having radial grooves for insertion of the same. It consists in its ends of some clamps that link the different sections in which the rotor would be divided by effect of the passing vanes. The rotor also has a series of symmetrically distributed relief reliefs of their weight.

La bomba se encuentra totalmente sumergida en la balsa de orujos y dispone de ruedas para su desplazamiento por el fondo de la misma, así como de un motoreductor hidráulico acoplado al eje de giro del rotor y otro para su desplazamiento. La velocidad de giro del rotor es baja debido a que el producto a bombear son fangos o lodos.The pump is fully submerged in the  Pomace raft and has wheels for movement through the bottom of it, as well as a coupled hydraulic gearmotor to the axis of rotation of the rotor and another for its displacement. The Rotation speed of the rotor is low because the product pumping is mud or sludge.

La cavidad de recepción del líquido o cámara de aspiración se encuentra en la parte inferior de la bomba, llenándose el espacio comprendido entre dos paletas consecutivas, el rotor y el estator. La cavidad de descarga o cámara de impulsión se encuentra en la parte superior produciéndose una compresión de los fangos trasegados debido a la posición excéntrica del rotor.The receiving cavity of the liquid or chamber of suction is located at the bottom of the pump, filling the space between two consecutive palettes, the rotor and stator. The discharge cavity or discharge chamber is found at the top producing a compression of the rear sludges due to the eccentric position of the rotor.
