Abstract

Varios aspectos de la descripcion se dirigen a proporcionar estructuras que definen un espacio radial entre un impulsor y un elemento de carcasa de bomba que facilita la minimizacion del movimiento del fluido hacia el espacio radial de una manera que disminuye el impacto, y la consecuente degradacion, de la superficie interna del elemento de la carcasa de la bomba al mover las particulas abrasivas fuera del espacio radial, lo que se logra al proporcionar un arreglo de entrada de aspiracion de un impulsor y un elemento de carcasa de bomba que estan en angulo desde el ojo del impulsor hasta la periferia exterior del impulsor en una direccion contraria al protector trasero o al lado de accionamiento del impulsor y hacia un primer extremo de la carcasa de la bomba en el que se introduce fluido en la carcasa de la bomba.
