The ESPA NOX 50 model is designed for more demanding filtration circuits where a flow rate of 12 m³/h is required. The self-priming capability simplifies start-up and minimises the risk of air entering the system.
The all-plastic pump section resists aggressive pool chemistry without corrosion, while the AISI 420 stainless steel shaft and graphite mechanical seal ensure reliable sealing throughout the entire season. The surface-treated aluminium motor housing efficiently dissipates heat during continuous operation.
The pump serves as a direct replacement for older Iris 750 models with the same hydraulic performance and connection dimensions. Thanks to its performance/price ratio, the NOX 50 is one of the most popular models for medium-sized private pools.
