SENA Pump

New generation pump range. Motors from 1/3 HP to 1.25 HP in single-phase and from 3/4 HP to 1.25 HP in three-phase motors. GS marking. IP-55 Motor protection, Class F insulation. All parts in contact with water made of S.S. AISI-316. Ø 50 mm solvent weld fittings for connection. Flow rates given at 6 m head for 1/3 HP, 8 m head for 1/2 HP, and 10 m head for the rest of the range. 3,000 rpm.

Stainless steel nuts and bolts for the pump - 1.5" suction and return connectors for Ø 50mm tubing. - Mechanical closure manufactured in AISI 316. - NORYL (R) impeller. - Pump body and diffuser manufactured of polypropylene with mineral filler and fibreglass. - Class F insulation and IP-55 motor protection for operation in high-humidity, high temperature environments. - Self-priming at more than 2 m. - Standard 50 Hz range; also available in 60 Hz. - Sena pumps run at full duty with optimal noise levels for all models, thereby minimizing the effects of noise on the pool surroundings. - Includes a bayonet closure in the prefilter lid, making it possible to close the pump prefilter in four different positions in just one step. - The cross-shaped prefilter lid means any tool can be used to open or close it. - A highly stable, easy-to-assemble foot has been used to attach the foot to the pump body, eliminating the need for nuts and bolts.

The high flow rating and low noise level of Sena pumps go hand in hand to meet all the needs of private pools with an attractive design that is characteristic of AstralPool equipment. A special feature of this pump version is its self-priming capacity: at more than 2 m without a foot valve. In addition, Sena pumps are manufactured with engineering plastics and have a 2-litre prefilter fitted with a transparent lid for viewing the inside of the prefilter. Sena pumps are available with power ratings ranging from 1/3 HP to 1.25 HP with single-phase motors and 3/4 HP to 1.25 HP in three-phase motors, making it possible to run at 230 V and 230/400 V ± 10%, due to the use of Euro-voltage motors.

Characteristics:
• Stainless steel nuts and bolts for the pump
• 1.5” suction and return connectors for Ø 50mm
tubing.
• Mechanical closure manufactured in AISI 316.
• NORYL ® impeller.
• Pump body and diffuser manufactured of
polypropylene with mineral filler and fibreglass.
• Class F insulation and IP-55 motor protection
for operation in high-humidity, hightemperature
environments.
• Self-priming at more than 2 m.
• Standard 50 Hz range; also available in 60 Hz.

Low noise level
Sena pumps run at full duty with optimal noise levels for all models, thereby minimizing the effects of noise on the pool surroundings.

Practical design
The entire range of Sena pumps includes a bayonet closure in the prefilter lid, making it possible to close the pump prefilter in four different positions in just one step. The cross-shaped prefilter lid means any tool can be used to open or close it. In addition, a highly stable, easy-to-assemble foot has been used to attach the foot to the pump body, eliminating the need for
nuts and bolts.
