Heating system

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.

Solar, air energy heating systems

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.

Domestic hot-water systems

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.

Cooling and air-conditioning systems

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.

Household booster systems

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.
