AirLift Pump - 2 inches

grabcad

A simple yet practical design is used for this sludge or sewage handling system, which mainly consists of commercial PVC pipes and fittings that are either glued or welded. It finds application in water treatment processes, aquaculture, and agriculture, primarily to lift fluids a few inches or transfer them to another vessel. The air source comes from low-pressure, high-flow equipment such as regenerative turbine pumps or rotary vane compressors and is not dedicated. To ensure proper functioning, inlet air pressure/flow needs to be regulated through a valve, with an ideal pressure of around 60 inches of water (2 psi more or less). In Spanish, this system is called Bombas de Elevación por Aire: Diseño sencillo pero muy util; utilizado en acuicultura, tratamiento de aguas residuales, agricultura, etc.; para elevar líquidos y lodos unas pocas pulgadas y transvasarlos. La alimentación de aire proviene de una fuente de baja presión, alto caudal (como una bomba de turbina regenerativa o compresor de lóbulos rotatorio). Casi nunca dedicado; la entrada de aire se debe regular con válvula y así ajustar la salida; la presión del aire debe estar por el orden de las 60 pulgadas de agua (apenas unas 2 libras).
