          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格林進口熱水循環(huán)泵性能特點：
1、軸封：可選配軟填料密封和機械密封。  
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。  
4、承壓：設計壓力為4.0MPa，承壓高。  
5、軸承：軸承選用圓柱滾子軸承與兩個角接觸軸承配套，采用稀油潤滑，承載能力顯著提高。軸承設計壽命25000小時。  
6、高效節(jié)能：采用CFD計算流體動力學，分析計算出泵內(nèi)壓力分布和速度分布關系、優(yōu)化泵的流道設計，確保泵有高效的水力形線，提高了泵的效率。  
7、耐高溫結構：泵體采用中心支撐方式，解決了泵在輸送高溫介質(zhì)時防止高溫下泵組熱膨脹不一致而造成的應力集中以及聯(lián)軸器對中心發(fā)生改變。泵支架、泵蓋、懸架體(軸承部位)及機封壓蓋均有冷卻腔，可在不同溫度時分別用冷卻水冷卻或風冷卻。
