Pool Spa Pumps: Silen and NOX

Preguntas frecuentes sobre Spa Pumps

Why are Espa pumps so well known?

Espa is a Spanish manufacturer with a long history of producing water pumps. Its pool pumps, such as the Silen and NOX series, stand out for their quiet operation, efficiency, and motor quality.

What is the difference between the Espa Silen and the Espa NOX?

Both are self-priming pumps with a prefilter for residential pools. The Silen is designed to operate especially quietly, while the NOX is a robust range for intensive use. Check each product specification for the flow rate the model delivers at your installation height.

How do I know what power Espa pump I need?

Divide your pool volume in m³ by 4 to find the required hourly flow rate, then look for a model that achieves it at 10 m.w.c. without exceeding your filter’s maximum flow rate.
