Air Operated Double Diaphragm Pump
Product Description:
It’s unneccessary to pour the drawing water, the suction lift reaches 7m height, the delivery lift reaches 70m length and the outlet pressure ≥ 6 kgf/cm3. Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. The damage is very less to the pump while exhausting the slurry and imperity. The delivery lift and flow can pass the pneumatic valve opern to realize the stepless adjustment (the pneumatic pressure adjustment is between 1-7kgf/cm3. This pump has no rotary parts and no bearing seals. The diaphragm 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 danger while exhausting the toxin and flammable or corrosive medium. No need electricity power. It’s safe and reliable while using in the flammable and explore places. It can be soaked in medium to work. 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 be damaged caused by this. Once overloading, the pump will automatically stop and possesses the selfprotection function. When the load recovers normally, it also can start automatically. Simple structure and less wearing parts. This pump is simple in struction, installation and maintenance. The medium conveyed by the pump will not touch 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. This pump needn’t the oil lubricant. Even if idling, it has no influence to the pump. This is a specail characteristic of this pump.ModelFlow (m3/h)Head (m)Suction head (m)The max particles passed (mm)Max pressure (kg/cm2)Caliber (mm)QBY-100-0.80-5051710QBY-150-15115QBY-250-2.472.525QBY-400-874.540QBY-500-127850QBY-650-167865QBY-800-2471080QBY-1000-30710100
