Description
Astralpool pump body screw set 4405011440
The Astralpool pump body screw set 4405011440 is an original fastening kit used to secure the pump body, seal plate and related
components on compatible Astralpool pool pumps. With correctly dimensioned screws and matching heads, this set ensures a solid,
vibration resistant assembly of the wet end for reliable daily filtration.
Main features of the Astralpool pump body screw set
- Original Astralpool screw set for compatible pump bodies.
- Includes the specific number and length of screws required for the housing.
- Designed for secure clamping of pump body, seal plate and associated parts.
- Metal quality chosen for use in humid technical rooms around pools.
Function in the pump assembly
The screws in the 4405011440 kit hold the pump body firmly against the seal plate and motor flange. Correct tightening keeps the
internal geometry stable, protects the mechanical seal and gaskets and helps the pump maintain its original performance curve without
excess noise or vibration.
- Clamp the pump body and seal plate together around the mechanical seal.
- Maintain alignment between the hydraulic section and motor shaft.
- Support leak free operation by keeping gaskets evenly compressed.
Compatibility and use cases
The Astralpool pump body screw set 4405011440 is intended for specific Astralpool circulation pumps that list this code for their body
fastener kit in the exploded view. It is particularly useful when rebuilding a worn pump, replacing a damaged housing or whenever the
original screws are corroded, missing or have damaged heads.
- Suitable for Astralpool pumps that specify 4405011440 as body screw kit.
- Ideal for full wet end refurbishment or housing replacement.
- Recommended when existing screws show corrosion or stripped heads.
Always verify the reference against the official parts diagram of your pump model before ordering to ensure correct compatibility.
When to replace the pump body screws
Although the screws are not directly in contact with pool water, they work in a humid environment and are subject to vibration and
mechanical stress. Over time they can corrode or the heads can deteriorate, making safe tightening and future disassembly difficult.
- Visible rust or pitting on the screw shank or head.
- Rounded or damaged heads that no longer accept the correct tool.
- Missing screws or mismatched hardware of different lengths or qualities.
- Major pump service where the wet end is fully dismantled and rebuilt.
Installation guidelines
Installing the Astralpool pump body screw set 4405011440 is carried out during pump assembly or reassembly. The system must always be
isolated electrically and hydraulically before working on the pump.
- Switch off the power supply, close valves and drain the pump housing.
- Position the pump body, mechanical seal, seal plate and gaskets according to the manufacturer sequence.
- Insert the new screws by hand in their original locations to avoid cross threading.
- Tighten the screws gradually in a criss cross pattern so the body and seal plate pull together evenly.
- Avoid overtightening, which can distort plastic components or crush gaskets.
After reassembly, prime the pump, start filtration and check for leaks and abnormal noise, which may indicate incorrect alignment or
insufficient clamping.
Good practice for long term reliability
Using the correct Astralpool pump body screw set and following good installation practices helps keep the pump stable and serviceable
over many seasons.
- Use appropriate tools with clean bit profiles to avoid damaging screw heads.
- Check screw tightness during major services and re tighten gently if necessary.
- Protect the technical area from excessive humidity and condensation where possible.
- Replace screws preventively if you see early signs of corrosion during inspection.
With the Astralpool pump body screw set 4405011440 correctly installed, compatible pool pumps benefit from secure housing fixation,
easier maintenance and reliable hydraulic performance in everyday operation.
