          進(jìn)口熱水循環(huán)泵主要用于冶金、電站、輕紡、化工、采暖及余熱利用系統(tǒng)中的管路或封閉回路中的熱水循環(huán)或有機(jī)熱交換介質(zhì)的輸送。對輸送熱交換介質(zhì)的泵來說，介質(zhì)與泵是處在高溫下，而系統(tǒng)壓力是不高的。

英國GRIMM格林進(jìn)口熱水循環(huán)泵結(jié)構(gòu)說明：
          GRS型泵為臥式徑向剖分，后開門，單級單吸蝸殼式離心泵。泵的連接尺寸按照ISO2858/DIN 24256，腳支撐式。
          GRSY、GRY為臥式，徑向剖分，后開門，單級單吸蝸殼式離心泵。泵連接尺寸按照ISO2858/DIN 24256，中心線支撐式。

英國GRIMM格林進(jìn)口熱水循環(huán)泵性能特點(diǎn)：
1、軸封：可選配軟填料密封和機(jī)械密封。  
2、聯(lián)軸器：采用彈性柱梢聯(lián)軸器，傳動精度高。  
3、輔助管路：按API 610第8版要求配置。
