熱水采暖系統Heating system
DS系列屏蔽循環泵適用于集中供暖及分戶供暖系統的熱水循環。
該水泵能在三檔轉速下運行。
水泵適用于單管供熱系統，雙管供熱系統，地板采暖系統以及混合回路供暖系統。
DS series circulation pumps are specially designed for central and district heating systems.
The DS pumps can be operated at three different speeds.
The pumps are used primarily for one- and two-pipe heating systems, underfloor heating systems, also suitable for mixing loops in large systems.
太陽能、空氣能熱水系統Solar, air energy heating systems
DS系列屏蔽循環泵適用于太陽能及空氣能供熱循環系統。
在這種應用下，水泵必須能處理以下幾種情況：
l 輸送液體含有防凍劑
l 液體溫度過高
l 溫度波動范圍大
DS系列屏蔽循環泵設計精良，適用于上述特殊情形。在水泵啟動時，如果室外溫度較低，則管道內的水會很冷，流入水泵后會導致定子內部出現冷凝水，因此DS系列選用復合涂層的漆包線，且定子外殼設計有專門的冷凝排水孔。DS系列流體部件選用耐高溫的特種工程塑料，可以承受短時間的最高達140℃的高溫液體。
DS series circulation pumps are applicable for circulation in solar heating systems and air energy heating system,
Solar and air energy systems often operate with very low flow compared to other heating systems, and the pump must be designed to handle
l water with anti-freeze
l high liquid temperatures
l large temperature fluctuations.
The DS pump is optimised for operation specifically under these conditions. During start-up at low outside temperatures, the stagnant water inside the pipes may be very cold and may create condensed water inside the stator. Therefore, the DS pump windings are double-coated, the stator housing has drain holes. The DS pump components contacting with fluid use heat-resistant material and can work with temperatures up to 140 °C for a short time.
生活熱水系統Domestic hot-water systems
DST系列智能溫控泵特別適用于生活熱水加速循環，實現水龍頭一開熱水即來，避免浪費和等待。
PPS工程塑料泵殼更適合衛生熱水。
建議水泵工作時的液體溫度低于65℃，以消除鈣質結垢的風險。
DST series temperature cotroller pumps are specially designed For accelerated circulation in domestic hot-water supply system. Tap running and hot water arrive, no water waste and no waiting.
PPS composite pump housing is more suitable for sanitary water.
It is recommended to keep the operating temperature lower than 65 °C to avoid lime precipitation.
冷卻及空調系統Cooling and air-conditioning systems
工業設備冷卻及空調系統，可根據類型和尺寸大小選用德魯普DS系列屏蔽循環泵。 DS系列對冷水和熱水系統循環均適用。
溫度范圍：-25℃至+110℃
For cooling and air-conditioning systems, use DS pumps depending on type and size.
These pumps are suitable for circulation both of cold and hot water.
Temperature range: -25 °C to +110 °C.
家用增壓系統Household booster systems
DSA系列家用自動增壓泵可以為民用住宅內的冷熱水增壓。
DSA系列水泵用于開式系統中，能夠與供水管路直接連接，配備水流開關，在水龍頭打開或關閉時能自動開啟或關閉水泵。
DSA series household booster pumps are used for cold/hot water boosting in domestic buildings.
DSA series pump used in the open system and can be connected directly in the water supply pipes. With flow-switch installed, the pump can be switched on and off automatically by turning the taping water on and off.
