Shinjo Valves-QBY AL-alloy diaagm 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 ≧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.3.The delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment(the pneumatic pressure adjustment is between 1-7 kgf/cm2) ;4.This pump has no rotary parts and no bearing seals.The diaagm will completely separate the exhausted medium and pump running parts,working medium.The conveyed medium can t be leaked outside.Thus it will not cause the environmental pollution and human body safety dangerous whils exhausting the mmable or corrosive medium.5, No electricity. It s safe and reliable while using in the flammable and explire places.5.It can be soaked in medium.6.It s convenient to use and reliable to work..Only open or close the gas valve body while starting or stopping.Even if no medium operation or pausing suddenly for long time because of accident matters,the pump will not bedamaned caused by this.Once over-loading,the pump will automatically stop and possesses the selfprotection function.When the load recovers normally,it also can start automatically.7.Simple structure and less wearing parts.This pump is simple in structure,installation and maintenance.The medium conveyed by the pump will not touth the matched pneumatic valve and coupling lever etc.Not like other kinds pumps,the performance will drop down gradually because of the damages of rotor,gear and vane etc.8.It can transmit the adhesive liquid(the viscosity is below 1000 centipoise).
