Pumping stations

Definition

Pumping stations are facilities designed to move fluids, such as water or geothermal fluids, from one location to another through the use of pumps. In district heating systems, these stations play a crucial role by ensuring the efficient transport of heated water from the central plant to residential and commercial buildings. Their design and operation are essential for maintaining pressure and flow rates, which are critical for effective heat distribution.
