Technical characteristics
Swimming pool pump Astralpool Sena 1/2 hp single-phase - 25462
Design and high performance
In the Sena family of pumps, both maximum flow and low noise levels 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. It is worth highlighting their self-suction capacity, over 2 metres without a foot valve. In addition, the Sena pumps are made of technical plastics with a 2-litre pre-filter and a transparent cover that allows the inside of the pre-filter to be seen.
The Sena family is available from 1/3 CV to 1.25 CV with single-phase motors and from 3/4 CV to 1.25 CV in three-phase motors, allowing them to work at 230 V and 230/400 V with a variation of ± 10% with respect to the nominal voltage due to the fact that they incorporate Eurovoltage motors.
Sena pumps comply with the specifications of the EN-60335-2-41\A1:2001 standard, which has led to them obtaining the TÜV-GS mark.
Simple and reliable
Sena pumps are a simple solution for pumping water from pools and water features with low to medium flow requirements. Pumps are easy to install thanks to the fittings already included.
Small dimensions
Built to be a compact self-priming pump. All Sena references are shorter than 490 mm and narrower than 200 mm. A pump that fits even in the smallest technical boxes and cabins.
For all types of pools
Available in single-phase and three-phase motors, Sena pumps can handle 3.5 to 16 m3/h. Supports all common chemical treatments, including saltwater chlorination.

Low noise level
Sena pumps work at full performance with an optimum noise level for all models, so that the perceived noise effects in the pool environment are minimised.
Practical design
The entire range of Sena pumps incorporates the bayonet fitting 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. Also, to fix the foot to the body of the pump, we have chosen a foot of great stability and easy assembly, eliminating the screws as one of its components.
