The Nadorself countercurrent pump from Espa is a self-priming and compact centrifugal electric pump for the transfer of large flows, specially designed for countercurrent swimming equipment in private, collective and public pools, in balneotherapy or thalassotherapy centers or in private or public gyms and spas.

This equipment can transform a pool into a space enabled for leisure, sports and health, especially in small pools.

The self-priming capacity of this model – realized thanks to a front suction flap – allows great flexibility in the installation, which can be carried out in technical rooms without the need for works in the part adjacent to the pool basin.

Its configuration in plastic materials provides great resistance to the corrosion of pool water, regardless of the disinfection system used.
