sera Flore CO2 500 impeller set with vertical tube replacement SE-08071 (aquarium CO2 pump parts)

Replacement impeller set for the sera Flore CO2 500 unit, designed to restore smooth operation of the CO2 dosing pump. This kit contains the rotating impellers and a vertical tube intended for the internal circulation path of the CO2 pump assembly used in planted aquariums. It is intended for routine maintenance and repair of compatible sera Flore CO2 500 devices to reduce noise, vibration and restore original flow characteristics.

Advantages

The set provides direct replacement parts matched to the sera Flore CO2 500 design so wear-related issues can be addressed without replacing the entire unit. Replacing the impellers and vertical tube can reduce excessive noise and vibration, improve pump efficiency and help restore consistent CO2 delivery to the aquarium. Using original-design components simplifies installation and helps maintain the intended hydraulic performance of the dosing system.

Suitable for

• Maintenance and repair of sera Flore CO2 500 dosing/pump units compatible with the original impeller assembly
• Restoring CO2 circulation performance in planted aquariums
• Reducing noise and vibration caused by worn impellers or damaged vertical tubes
• Routine preventive maintenance to extend the service life of the CO2 pump

When it may not be suitable

This impeller set is intended specifically for the sera Flore CO2 500 pump design; it may not fit other CO2 pumps or dosing units from different manufacturers or models. If the pump housing, motor or other major components are damaged or corroded, replacing the impeller set alone may not fully restore function. Verify physical compatibility with your unit before purchase.

How to use

Disconnect the CO2 unit from power and remove it from the aquarium following safety instructions. Open the pump housing according to the manufacturer's service instructions, remove the worn impellers and the vertical tube, and fit the replacement parts from this set into their correct positions. Reassemble the housing, reinstall the unit, and test the pump operation for smooth rotation and stable CO2 delivery. If uncertain, consult the device manual or a qualified technician.

What to consider before purchase

• Confirm physical compatibility with your sera Flore CO2 500 unit and the pump assembly design
• Inspect the pump housing and motor condition — impeller replacement may not fix mechanical or electrical faults
• Ensure parts are appropriate for aquarium use and properly seated to avoid leaks or imbalance

Usage recommendations

Perform regular visual checks and clean internal components periodically to prevent debris buildup. Replace impellers at the first signs of wear, unbalanced rotation, or persistent noise to maintain stable CO2 dosing in planted aquariums.
