Counter-Current Pump Espa Nadorself 300T - 54 m3 / h - 400 V

The Espa Nadorself pump represents the technological pinnacle in pool hydraulics, with its primary purpose being to power both commercial and private counter-current systems, hydromassage jets, and attractions requiring an enormous water flow. Unlike standard filtration pumps, which work with a smaller volume of water at higher pressure and are equipped with a prefilter to capture coarse debris, this unit operates on the principle of massive circulation without prefiltration. This allows it to instantly move a huge amount of water and create a strong, stable, and wide stream that can simulate a river current directly in the pool. As a result, even a smaller home pool can be transformed into a full-fledged sports and rehabilitation facility, where swimmers can train without having to constantly turn around at the end of the pool. The high level of electrical protection and special insulation class ensure that the pump can safely withstand the extremely humid environment of technical rooms. The integrated thermal protection continuously monitors the winding condition and, in the event of overheating risk, automatically disconnects the unit, protecting it from fatal damage and restoring operation once it has cooled down. The entire pump body, together with the internal diffuser and impeller, is injection-molded from an advanced technopolymer reinforced with glass fibers for maximum mechanical strength. The motor shaft is made of premium stainless steel, and a highly durable mechanical seal ensures perfect separation of the hydraulic and electrical parts. The hydraulic geometry itself, with an extra-large connection thread diameter, minimizes friction and pressure losses, which in practice means the pump can move more than fifty cubic meters of water in a single hour while maintaining high energy efficiency. The unit also features self-priming capability, but for ideal operating conditions and immediate stream start-up, installation below the pool water level is recommended.

Advantages:

High water flow: Ideal for creating a strong and smooth current for swimming in place.
Prefilter-free design: Enables direct and massive water transfer without hydraulic losses.
Top-grade material resistance: Technopolymer with glass fibers and stainless steel guarantee long service life and resistance to pool chemicals and salt water.
Integrated thermal protection: Protects the motor from burnout by automatically switching it off when overheated and turning it back on after cooling.
High electrical protection rating: safely withstands the extremely humid environment of technical rooms
Self-priming capability: Flexibility in installation (although the ideal position remains below the water level).
