Astralpool Sena pump

AstralPool Sena pool pump

AstralPool's Sena series of pool pumps has been designed so that the maximum flow rate and low noise level go hand in hand with the intention of fully satisfying the requirements of the private pool and with an attractive design that is already characteristic of AstralPool.

The pump's self-suction power stands out, above 2 m without foot valve. In addition, the Sena pumps are made of technical plastics with a pre-filter of 2 L capacity and its transparent cover allows the interior of the pre-filter to be seen.

The Sena pump series is available from 1/3 HP to 1.25 HP with single-phase motors and from 3/4 HP to 1.25 HP in three-phase motors allowing to work at 230 V and 230/400 V with a variation of ± 10% with respect to the nominal voltage due to the incorporation of eurovoltage motors.

Sena pump benefits

• Low noise level: Sena pumps work at full capacity with an optimum noise level in all models. This minimizes the perceived noise effects in the pool environment.

• Practical design: The entire range of Sena pumps incorporates the bayonet lock on the pre-filter cover, which allows the pump pre-filter to be closed in four different positions in a single movement. The cross configuration of the pre-filter cover allows any tool to be used to open or close it.

• To fix the foot to the body of the pump we have chosen a foot of great stability and easy assembly, eliminating the screws.
