Qinhuangdao Metropolitan through the main production pump: a single-screw pumps, progressive cavity pumps, New Territories, water pump, centrifugal pump, water pump selection and so on. 
 Use: 
 Since the two parts of the special geometry, respectively, to form a separate sealed chamber capacity, medium introduced by the uniform axial flow, internal flow rate is low, the volume remains constant, steady pressure, and thus will not produce vortex and agitation. Each level of the pump output pressure is 0.6MPa, head 60m (water), self-absorption a height of 6m above. 
 Due to the stator use a variety of flexible material, so this pump for high viscosity fluid delivery and media containing suspended particles or rigid media with fiber transmission, has a general kind of incompetence pump characteristics. Proportional to the flow and speed. 
 Single screw pump compact, small size and easy maintenance. Adaptability of the media, smooth flow, pressure pulsation, high self-priming capability. Operating temperature up to 120 ℃, if need transport medium temperature 120 ℃ -350 ℃, can be customized. Widely used in food, metallurgy, paper making, printing and dyeing, chemical, fertilizer, pharmaceuticals and other industrial sectors.
