The ESPA Silen I 33 pump belongs to the Silen I series, which differs from the standard NOX series in lower noise thanks to the improved hydraulic profile of the impeller. With a flow rate of 8 m³/h, it covers the filtration needs of medium-sized pools.
The self-priming design simplifies installation and start-up, while the all-plastic pump section resists pool chemistry without corrosion. The stainless steel shaft and graphite mechanical seal ensure long-lasting tightness and minimal maintenance requirements.
The pump is designed as a direct replacement for Iris 500 models and is compatible with the ESPA flange collar, which facilitates connection to various types of Niper, Iris, Silen, and NOX series pumps. Thanks to its quieter operation, the Silen I 33 is particularly suitable for pools near living spaces.
