DR型系列泵，專(zhuān)用于高溫熱油加熱場(chǎng)合或類(lèi)似的熱媒環(huán)境，選用具有較高的磁能積和極低的溫度系數，溫度穩定性和化學(xué)穩定性高的磁性材料，可輸送溫度至400℃的熱傳送流體，是一種理想的高溫熱油循環(huán)泵。
      DR series pumps are specially designed for applications with high temperature hot oil heating or similar thermal media environment; they are made with magnetic materials with high magnetic energy product and extremely low temperature coefficient, and high temperature and chemical stability, to transfer heat transfer fluid with temperature up to 400℃, hence an ideal high temperature heat transfer oil circulating pump. 

1. 單級單吸離心式結構。

2. 安裝支撐面在泵軸心線(xiàn)的水平面上。

3. 獨特的內部循環(huán)和冷卻散熱系統，保證了內置滑動(dòng)軸承和磁傳動(dòng)部件的使用壽命。

4. 根據熱媒體溫度，必要時(shí)對內部循環(huán)液和泵支架等進(jìn)行冷卻，冷卻液量每只管路0.3～0.7m3/h，壓力0.2～0.3MPa。

5. 當采用外部循環(huán)液時(shí)，壓力應高于泵腔內的壓力0.07～0.1MPa，如果輸送易汽化介質(zhì)時(shí)，應高于汽化壓力0.175～0.2MPa。
