One cannot avoid to speak of their self-suction capacity, above 2 meters without valve with base. Moreover, the Sena pumps are constructed of plastic, techniques with a pre-filter of 2 liters capacity, and have a transparent cap which allows viewing within the pre-filter.
The Sena family is available from 1/3 CV up to 1.25 HP with single-phase motors and from 3/4 hp up to 1.25 HP in three-phase motors, allowing it to work at 230V and 230/400V with a variation of ± 10% compared to the nominal voltage, since they include Euro-tension motors.
Sena pumps respect what is determined by the legislation that led to the obtaining of the TÜV-GS mark. Practical design.
Self-suction capacity above 2 meters. Standard 50 Hz range, also available at 60 Hz. Low sound. Sena pumps work at full efficiency with an excellent sound level for all models, in fact the sound effects perceived in the pool environment are minimized.
The whole range of Sena pumps includes bayonet locking on the pre-filter cap, which allows the pump pre-filter in four different positions to be closed in one movement. The cross-type configuration of the pre-filter cap ensures that any tool can be used to open or close. Moreover, to fix the base to the pump body, a base of great stability and simple assembly was chosen, eliminating the screws.
