Submersible pumps

If the delivery head exceeds nine meters, a submersible pump is needed. It pumps the medium, usually groundwater, typically into a storage tank. Submersible pumps are often controlled by a pressure switching cycle: If the pressure falls below a defined level, the pump restores the desired maximum pressure in the tank. In smaller domestic water systems, however, demand-controlled activation without intermediate storage can also be useful, so that the pump delivers the water precisely when it is needed. OSNA’s reliable submersible pumps can be found in domestic and industrial water supply systems, in industrial and municipal facilities, as well as individual special versions used in mining.
