Low sonority. The Sena pumps work at full capacity with an optimum sound level for all models, so that the perceived sound effects in the pool environment are minimised.

Practical design. The entire Sena pump range has a bayonet fitting on the pre-filter cover, which allows the pump pre-filter to be closed in four different positions in one single movement. The cross configuration of the pre-filter cover allows any tool to be used to open or close it. Also, to fix the foot to the pump body, a very stable and easy to assemble foot has been chosen, eliminating the screws as one of its components.
