Pneumatic double diaphragm pump is a new type of conveying machinery, using compressed air as the power source, for a variety of corrosive liquids, with liquid particles, high viscosity, volatile, flammable, highly toxic liquid, can be pumping Exhausted. Germany Hank (HANK) pneumatic double diaphragm pump is widely used in various industries, product quality acclaimed. The pump does not need to irrigate the water, both pumping the flow of liquid, but also transport some easy flow of the medium, suction high, adjustable head (0-50 m) air pressure only need to be greater than 1kg / cm2 that can work, Absolute fire protection, with a submersible pump, self-priming pump, impurity pump, shielding pump, mud pump all the features and many characteristics of the conveyor machinery.
Pneumatic double diaphragm pump with compressed air, nitrogen or natural gas as a power. The main directional (pneumatic) control valve distributes the compressed air to the gas chamber and applies a uniform pressure to the inner surface of the diaphragm. While the discharged gas is discharged from the rear side of the pump through the valve assembly guide port. Pneumatic double diaphragm pump chamber gas pressure exceeds the liquid chamber pressure, diaphragm link back and forth movement, in one side of the discharge, in the other side of the suction. The direction of the discharge and suction of the liquid is controlled by the direction of the check valve (ball valve or sheet valve). The suction stroke causes the pump to perform inhalation. The suction stroke reduces the chamber pressure and increases the chamber volume. Thereby generating atmospheric pressure differential pressure, to promote the liquid through the suction pipe, through the suction side of the check valve, into the external liquid chamber. The suction side travel also initiates the reciprocating (displacement, stroke or cycle) movement of the pump. Pneumatic double diaphragm pump Moves the suction diaphragm through the stroke Mechanical movement The diaphragm of the double diaphragm pump comes into contact with the aligned drive plunger and moves the pilot spool. When the pilot valve is activated, it will send a pressure signal to the other end of the main directional valve. The pneumatic double diaphragm pump will reverse the direction of the compressed air to the other side of the internal chamber so that the continuous conveyance of the medium is completed.
1, pneumatic diaphragm pump does not produce spark: Pneumatic diaphragm pump without power for power, ground and then prevent the static spark.
2, not overheating: compressed air for power, in the exhaust is a process of expansion and endothermic, pneumatic pump work is the temperature is reduced, no harmful gas discharge
3, can be through the liquid containing particles: because the volume of work and import for the ball valve, it is not easy to be blocked.
4, the material shear force is very low: how the work is sucked into how to spit out, so the smallest material agitation, for the transport of unstable substances.
5, the flow can be adjusted, you can install the throttle at the material exit to adjust the flow.
6, pneumatic diaphragm pump with self-priming function.
7, you can run empty, and not dangerous.
8, can dive work.
9, pneumatic diaphragm pump can transport the fluid is very wide, from low viscosity to high viscosity, from the corrosive get sticky.
成立于1852年创建于门兴格拉德巴赫（Monchengladbach）是位于德国北莱茵-威斯特法伦州首府杜塞尔多夫市以西的一座城市。于19世纪50年代初德国经济快速发展，由于德国能源短缺，政府在节能方面加大力度，因此HANK(Trouble Less pump没有故障的水泵)公司成立。汉克水泵是以生产高品质、先进的水泵、测量及控制系统而享誉全球的跨国性生产企业，在全球几十个国家拥有子公司及分支机构，公司产品涉及用途：石油、化工、电力、冶金、制药、食品、水处理、市政给排水、天然气、造纸、电子工业、楼宇、机械设备配套等领域。
GERMANY HANK PUMP LIMITED is founded on 1852 in Monchengladbach,which is located at one city in North Rhine in Germany, which is the west of Nordrhein-Westfalen. At the beginning of 1850s, as the rapid development of economic and the shortages of energy in Germany , the government had been in saving energy aspect. On this occasion, HANK Pump (Trouble Less Pump) was established.Hank pump is the world-famous transnational production enterprise,which produces high quality and advanced pump, measurement and control system, and which has its divisions and branches in dozens of countries in the global. The company products user involves the petroleum, the chemical industry, the electric power, the metallurgy, the drugs manufacture, food, the water treatment, the municipal administration to give draining water, the natural gas, the papermaking, the electronics industry, the building, the mechanical device necessary ect..
The conclusion of the pump concept in German Hank pump is resposibility,foresight,innovation. For ourselves resposibility, foresight and focusing on creating unprecendented solution and concept,our company has become the lead of pump manufacturer in the global.标签:   气动双隔膜泵 进口气动双隔膜泵
