HK 系列机械隔膜计量泵
HK series mechanical diaphragm metering pump

    HK系列机械隔膜计量泵是可按各种工艺流程的需要，输送水及类似水的化学液体以及腐蚀性和非腐蚀性液体的一种往复式容积泵，流量可在0-****范围内调节，产品执行中国国家标准GB/T7782-2008及参照国际****设计理念设计并生产。
产品广泛应用于石油、化工、水处理、环保、食品、轻工、造纸、制药、印染、冶金、矿山、电镀等行业。
The metering pump is a special reciprocating displacement pump, which the discharge can be infinitely regulated between 0 and **** to feed corrosive and non-corrosive liquid at a certain amount for the purposes of different process flows. The products comply with GB/T7782-2008 metering pump standard.
HK series mechanical diaphragm metering pumps are extensively used in such industries and sectors as petroleum, chemical, water treatment, environmental protection, food, light industry, paper-making, pharmacy, dyeing and finishing, metallurgy, mining and electroplating industry.
