热水采暖系统Heating system
DS系列屏蔽循环泵适用于集中供暖及分户供暖系统的热水循环。
该水泵能在三档转速下运行。
水泵适用于单管供热系统，双管供热系统，地板采暖系统以及混合回路供暖系统。
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.
太阳能、空气能热水系统Solar, air energy heating systems
DS系列屏蔽循环泵适用于太阳能及空气能供热循环系统。
在这种应用下，水泵必须能处理以下几种情况：
l 输送液体含有防冻剂
l 液体温度过高
l 温度波动范围大
DS系列屏蔽循环泵设计精良，适用于上述特殊情形。在水泵启动时，如果室外温度较低，则管道内的水会很冷，流入水泵后会导致定子内部出现冷凝水，因此DS系列选用复合涂层的漆包线，且定子外壳设计有专门的冷凝排水孔。DS系列流体部件选用耐高温的特种工程塑料，可以承受短时间的最高达140℃的高温液体。
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.
生活热水系统Domestic hot-water systems
DST系列智能温控泵特别适用于生活热水加速循环，实现水龙头一开热水即来，避免浪费和等待。
PPS工程塑料泵壳更适合卫生热水。
建议水泵工作时的液体温度低于65℃，以消除钙质结垢的风险。
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.
冷却及空调系统Cooling and air-conditioning systems
工业设备冷却及空调系统，可根据类型和尺寸大小选用德鲁普DS系列屏蔽循环泵。 DS系列对冷水和热水系统循环均适用。
温度范围：-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.
家用增压系统Household booster systems
DSA系列家用自动增压泵可以为民用住宅内的冷热水增压。
DSA系列水泵用于开式系统中，能够与供水管路直接连接，配备水流开关，在水龙头打开或关闭时能自动开启或关闭水泵。
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.
