For clean and slightly polluted water
The pumps of this subcategory are divided into two groups. The first of them are pumps for cold, clean water, which are characterized by high head and lower efficiency as for this type of pump. Due to their construction and obtaining a relatively high pressure, they can be used in vertebral wells or similar tanks with a considerable depth of installation and the need for a longer pumping distance. Perfect e.g. for watering. Pumps for slightly contaminated water are characterized by relatively high efficiency and a lower head. Due to the hydraulic parameters, these pumps are used for pumping dirty water from flooded rooms and for pumping water from tanks.
