Technical characteristics
Nadorself pump
Self-priming and compact centrifugal pumps for moving large volumes of water.
Specially designed for counter-current swimming equipment in private, collective and public swimming pools, in balneotherapy or thalassotherapy centres or in private or public gyms and spas.
This equipment can transform a swimming pool into a space for leisure, sport and health, especially in small swimming pools.
The self-priming capacity of this model, which is achieved thanks to a front suction flap, allows for great flexibility in installation, which can be carried out in technical areas without the need for building work on the part adjacent to the pool basin. Its configuration in plastic materials makes it highly resistant to the corrosion of swimming pool water, regardless of the disinfection system used
Outstanding features of the Nadorself series:
It incorporates an original and useful 2 1/2" curved impulsion threaded adjustable to 3 positions and 2 1/2" threaded flanged fitting on the axial suction. The single-phase models incorporate thermal protection of the motor.
