Una bomba de acción simple tiene una sola cámara de fluido (single acting) Una bomba de acción doble (double acting) es el equivalente a dos bombas simples ubicadas lado a lado en el mismo cuerpo. El movimiento del pistón en una bomba doble ocurre de tal manera que al llenar una cámara la otra se vacía, y viceversa. Este arreglo permite duplicar la capacidad de la bomba con respecto a una bomba simple de diseño similar. En general, el flujo efectivo de las bombas recíprocas disminuye a medida que la viscosidad del fluido bombeado aumenta debido a que la velocidad de la bomba debe reducirse.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
