AL-alloy diaphragm pump Performance Summary QBY AL-alloy diaphragm pump not only can exhaust the flow liquid,but also can convey some uneasy flowed medium,with the merits of self-pumping pump,diving pump,shield pump,slurry pump and impurity pump etc: 1.It s unnecessary to pour the drawing water,the suction lift reaches 7 m height,the delivery lift reaches 70 m length and the export pressure â?§6kgf/cm2; 2.Wide flow and good performance.The diameter allowed to pass the max grain reaches 10 mm.The damage is very less to the pump while exhausting the slurry and impurity.
