Astralpool silentblock set for 0.75 to 1.25 HP pumps 4405010442
The Astralpool silentblock set for 0.75 to 1.25 HP pumps 4405010442 is an original anti vibration mounting kit designed to support and
isolate compatible Astralpool pool pumps from the floor. By placing these elastic blocks between the pump base and the support slab, the
set helps to reduce noise, limit vibration transmission and protect the hydraulic connections in the technical room.
Main features of the Astralpool silentblocks 4405010442
- Original Astralpool silentblock set for 0.75, 1.0 and 1.25 HP pumps.
- Elastic mounts designed to absorb vibration from the motor and wet end.
- Suitable hardness for typical residential pool filtration applications.
- Dimensions matched to the fixing points on the corresponding pump base.
Function in the filtration installation
During operation, the motor and hydraulic section of a pool pump generate small vibrations that can be transmitted to the floor and
pipework. The Astralpool silentblocks 4405010442 act as an elastic interface between the pump base and the support, absorbing a
significant part of this energy. This helps keep the installation quieter and reduces mechanical stress on unions, valves and other
components connected to the pump.
- Decouple the pump from the floor to limit noise and vibration.
- Help protect suction and return pipework from micro movements.
- Contribute to a more comfortable acoustic environment around the plant room.
Compatibility and typical applications
This silentblock set is intended for Astralpool pool pumps in the 0.75 HP to 1.25 HP range that specify reference 4405010442 in their
exploded view or spare parts list. The number, size and thread of the mounts are configured to match the original holes in the pump
base, ensuring easy replacement or retrofit.
- Suitable for Astralpool pumps rated 0.75, 1.0 and 1.25 HP that use this silentblock set.
- Ideal for residential pool technical rooms where noise reduction is a priority.
- Recommended when relocating a pump or rebuilding an older installation.
Always check the pump identification label and parts diagram to confirm that 4405010442 is the correct silentblock reference for your
model.
When to replace the Astralpool silentblocks
Silentblocks are made from elastomer and work under compression over many hours of operation. With time, they can harden, crack or lose
elasticity, which reduces their ability to absorb vibration and can allow direct contact between pump base and floor.
- Visible cracks, tears or flattened areas on the rubber element.
- Pump base touching the support directly because the mounts have collapsed.
- Increased vibration or noise compared to earlier operation.
- Corroded or stripped threads on the metal studs or inserts.
Installation and good practice
Installing the Astralpool silentblock set for 0.75 to 1.25 HP pumps 4405010442 is straightforward and usually done when the pump is
being repositioned or the base is being renewed. Correct installation helps the mounts work efficiently and last longer.
- Switch off the pump and isolate the electrical supply before handling the unit.
- Support the pump, then unfasten it from the existing mounts or base.
- Fix the new silentblocks to the pump base or support according to the original layout.
- Set the pump back on the mounts, ensuring that all points are correctly seated and level.
- Retighten the fixings without overtightening, so the rubber still has room to flex.
After installation, check that the pump runs smoothly, does not rock on its supports and that noise and vibration are noticeably reduced.
Tips for a quiet and durable installation
Combined with proper pipe support and a solid foundation, the Astralpool silentblock set 4405010442 helps maintain a stable and quiet
filtration system.
- Install the pump on a rigid, level concrete slab or strong support.
- Support suction and return pipes independently to avoid hanging weight on the pump.
- Periodically inspect the mounts for signs of ageing or compression.
- Replace all silentblocks in the set at the same time for uniform behaviour.
With the Astralpool silentblock set for 0.75 to 1.25 HP pumps 4405010442 correctly installed, compatible pumps benefit from better
vibration isolation, quieter running and reduced mechanical stress on the entire filtration installation.
