Astralpool Sena pool pump exploded view

The Astralpool Sena pool pump exploded view gives a clear, detailed overview of all components that make up the pump. From the prefilter
lid and basket to the impeller, diffuser, housing and motor interface, each part is shown in its exact position and identified with a
reference number so you can easily find the correct spare part for your installation.

Overview of the Astralpool Sena pump range

The Astralpool Sena series is a family of self priming pool pumps designed for residential pools. All models share the same general
architecture with a large prefilter, corrosion resistant housing and quiet motor, while power and hydraulic performance vary between
sizes. The exploded view groups the common parts and highlights the few elements that change from one model to another, such as impeller
and diffuser versions.

How to read the exploded view

In the exploded diagram, each component of the Sena pump is shown separately but in the correct order of assembly. Every part has a
position number, which is linked to a parts list where you will find the official description and reference code. By comparing your
existing pump with the drawing and matching the numbers, you can identify exactly which piece you need to replace.

• Locate the zone of the pump concerned (prefilter, hydraulic body, motor side).
• Find the part visually on the exploded view and note its position number.
• Use the number to retrieve the exact spare part reference in the parts list.
• Check that the reference corresponds to your Sena model and power rating.

Main component groups shown

The Astralpool Sena pool pump exploded view is divided into several logical groups, which makes it easier to understand how the pump is
built and which parts work together.

• Prefilter section: transparent lid, lid o-ring, basket, housing inlet and drain plugs.
• Hydraulic body: pump housing, diffuser, impeller, shaft seal and internal gaskets.
• Motor interface: seal plate or backplate, fixing screws and alignment components.
• Base and connections: mounting foot, unions and connection fittings for suction and discharge.

Each group can be examined separately when diagnosing a leak, unusual noise or loss of performance, helping you decide whether a simple
gasket, a new impeller or a complete wet end is required.

Choosing the correct spare parts

When ordering spares based on the Astralpool Sena exploded view, it is important to check both the position number and the pump
specifications indicated on the motor nameplate. Some internal parts, such as impellers and diffusers, differ between models to match the
motor power and desired performance curve. Using the correct reference ensures that the pump will recover its original flow, pressure and
quiet operation after repair.

• Always note the full pump model and voltage from the identification label.
• Compare the dimensions of existing parts with the technical data when in doubt.
• Replace gaskets and o-rings at the same time as nearby mechanical parts where possible.

Benefits of using the exploded view for maintenance

Using the Astralpool Sena pool pump exploded view before disassembly helps you plan maintenance work, reduces the risk of assembly errors
and ensures that you order all necessary seals and fixings in one go. Whether you are replacing a mechanical seal, changing an impeller or
renewing the prefilter lid and basket, the diagram acts as a visual guide for correct reassembly of the pump.

By combining the exploded view with the official spare parts list, you can quickly identify and order the right Astralpool Sena pump
components, extending the life of the pump and keeping the filtration system running reliably for many seasons.
