The ESPA NOX 33 pump with a flow rate of 8 m³/h is a strong helper for pool filtration where smaller models are insufficient. The self-priming design allows it to easily overcome the difference in height between the water level and the pump during start-up.
The all-plastic pump section is resistant to pool chemistry and UV radiation, while the surface-treated aluminium motor housing efficiently dissipates operating heat. The AISI 420 stainless steel shaft and graphite mechanical seal form a long-term tight and maintenance-free solution.
This model is compatible with filtration replacing the original Iris 500 pumps, while maintaining the same connection dimensions for easy replacement. The robust design ensures reliable operation even with everyday, season-long use.
