Metering pump is widely used in petroleum, chemical industry, environmental protection, water treatment, plastic foaming, paper making, power plant, medicine as well as other scientific research and production departments. It is used to add pressure to pressure vessels and pipelines, or used to transport liquid quantificationally, its flux is carried out stepless regulation within 0-100％ when starting (or shutoff) (According to the features of metering pump, generally speaking, the minimum journey is no less than 30％ of the total journey at the time of using), and the metering precision can achieve ± 1％. Fluid end of this product can choose different materials according to corrosiveness of different mediums to cater for using requirements.

　　Flux regulation is realized through changing axial movement distance with eccentric shaft or N-shaped shaft to change stroke of plunger so as to achieve the target.

　　Flux range of metering pump: 0.16-18900L/h, max discharging pressure achieves 50Mpa, transportation medium temperature is from -30℃ to 120℃, the containing granule of liquid is less than 0.1mm, corrosive and non-corrosive mediums with viscidity of 0.2 ～ 1200mm2/S.

　　Besides, our company can make all kinds of special metering pumps, quantitative controllers, suit quantitative adding apparatuses as well as automatic alum-adding and chlorine-adding system for water factory according to users’ requirements, the precision of products can achieve 0.5％. meanwhile, we can make the products which can resist strong acid, strong alkali, organic solution, hot, cold, etc.
