Charles Austen HX88 Mini Series
Charles Austen HX88 Mini Pumps
Low-power adjustable pumps for desktop fountains, rock pools and very small water features
HX88 Mini is exactly what the name suggests: three tiny adjustable pumps for light circulation. HX8803, HX8805 and HX8807 provide 300, 450 and 650 l/h with power inputs of only 5, 6 and 8 W.
Charles Austen highlights the removable rotor assembly, multi-orientation mounting and built-in flow regulator. That makes the range useful for a tabletop feature or small reservoir where the water effect needs fine adjustment.
The low head figures are equally important. These are not miniature waterfall pumps; the largest model reaches a 1.2 m maximum head and useful flow will be lower well before that point.
Model Comparison
| Model | Maximum flow | Maximum head | Power |
|---|---|---|---|
| HX8803 | 300 l/h | 0.65 m | 5 W |
| HX8805 | 450 l/h | 0.75 m | 6 W |
| HX8807 | 650 l/h | 1.2 m | 8 W |
Maximum figures compare the models. Real flow falls as lift, pipe friction and connected equipment add resistance.
Designed for small effects
Use HX88 Mini for a desktop bowl, rock pool, short trickle or compact hydroponic pot system. The flow regulator lets the effect be softened without adding an external valve.
Keep hose short and avoid lifting water close to the maximum-head figure.
Flexible mounting and simple maintenance
The pump can be mounted in different orientations where the intake remains submerged and clear. The rotor assembly is designed for straightforward removal.
Fine grit is the enemy of a miniature impeller. Raise the pump slightly from a sandy base and use suitable screening.
A realistic expectation
A 300–650 l/h pump creates a small water effect, not a broad cascade. If the feature must rise or split between outlets, move to a larger range.
Our advice: HX88 Mini is excellent when “small and adjustable” is the brief. Do not ask it to compensate for narrow hose and excessive lift.

Frequently Asked Questions
Are HX88 Mini pumps adjustable?
Yes. The range includes a flow regulator.
Which is the lowest-power model?
HX8803 at 5 W.
Can HX8807 lift water 1.2 m?
That is its maximum head, where flow approaches zero; choose a larger pump for useful flow at 1.2 m.
Can the pump be mounted sideways?
Charles Austen states that the range can be mounted in different orientations, subject to correct submersion.
Can it run a tabletop fountain?
Yes, when the lift and desired flow are modest.
Can it run a pond filter?
It is too small for ordinary pond filtration.
Does it include a connector?
Charles Austen lists a barbed brass connector and manifold; check the exact model package.
Can grit damage it?
Yes. Protect the intake from sand and abrasive debris.
Does maximum flow tell me what reaches the outlet?
No. Maximum flow is measured at little or no head. Lift, pipe length, fittings and connected equipment reduce delivered flow.
Is maximum head the height for full flow?
No. It is the shut-off end of the curve, where useful flow approaches zero.
Should I use the largest practical pipe bore?
Yes. Generous, smooth pipework usually improves real flow and efficiency.
Can I throttle the pump with a valve?
Where permitted, a valve can trim flow, but heavy throttling wastes performance. Correct sizing or approved electronic control is preferable.
How often should the pump be cleaned?
Inspect and clean the intake and impeller whenever output falls and during routine pond maintenance.
Can you help me choose the model?
Yes. Send us the desired flow, vertical lift, pipe bore and length, fittings and connected filter or feature.
Why is my flow lower than the model name?
The model figure is a maximum comparison point, not the delivered flow through a real installation.
