This is a complete replacement head unit for the SUNSUN HW-703A canister filter. It suits aquarists whose filter head has failed or worn out and who want to restore the filter to its original working condition without replacing the whole unit.
Why it matters
- Complete assembly: the set includes the motor (water pump), main gasket, impeller, impeller cover with ceramic shaft and power cable, so the head can be replaced as one piece.
- Ceramic shaft: the impeller cover carries a ceramic axle, which is the component that supports the impeller's rotation.
- Secure mounting: two side clips hold the head in place on the canister.
- Restored performance: fitting the full head returns the filter to its original parameters.
What it works with
The head is designed specifically for the SUNSUN HW-703A canister filter and is listed in the aquarium filtration parts category. It is intended for aquarium filters and is not a universal part, so check model compatibility before ordering.

Frequently asked questions
The set includes the motor (water pump), two side clips, the main gasket, the impeller, the impeller cover with a ceramic shaft, and the power cable. It is a complete cover, not just a single part.
The motor is included, since the cover comes with its own motor (water pump) and impeller. You don't need to order these parts separately.
According to the supplier, replacing the whole cover restores the canister filter's original parameters. The description does not give further performance figures.
The gross price is 242.99 PLN. This is the complete cover set, so the price covers all the listed components.
This product is the head cover for the HW-703A model, so check that your filter is this model before ordering. If your filter is a different model, this cover is not the right part for it.
