The ESPA Nadorself 300T is a self-priming pump designed specifically as a drive unit for pool counter-currents, water spouts and water features. The self-priming capability up to a height of 4 m simplifies installation and eliminates the need to prime the pipework.
The pump body, impeller, diffuser and the suction and discharge flanges are made of chemically resistant technopolymer that withstands chlorinated and salted pool water. The AISI 431 stainless steel shaft and the aluminium mechanical seal with a graphite ring ensure a long, maintenance-free service life.
The motor with an aluminium alloy housing works on a three-phase 400 V supply and provides a flow rate of 54 m³/h. The pump is supplied without a power cable, the length and type of which is dimensioned by the electrical installation project of the specific construction. NBR/EPDM O-rings seal reliably even during temperature fluctuations.
