Charles Austen BP Pond Pumps
Energy-conscious pond circulation with optional remote flow control
The BP series is the controllable family in this part of the Charles Austen range. The current models on our site cover 6,000 to 11,000 l/h maximum flow, with strong published head figures and notably modest power inputs from the BP8000 upwards.
Charles Austen offers a separate paired remote receiver that can switch compatible BP pumps and adjust flow. That is useful on waterfalls and streams where the appearance changes with season or where full output is not needed all day.
The remote is an option, not a substitute for correct sizing. Choose a pump that reaches the required duty at full power, then use control to fine-tune it.
Model Comparison
| Model | Maximum flow | Maximum head | Power |
|---|---|---|---|
| BP6000 | 6,000 l/h | Check product data | Check product data |
| BP8000 | 8,000 l/h | 4.3 m | 49 W |
| BP10000 | 9,200 l/h | 5.8 m | 68 W |
| BP12000 | 11,000 l/h | 6.2 m | 92 W |
Maximum figures are comparison points measured under favourable conditions. Delivered flow falls as head and system resistance increase.
Optional remote control
The compatible receiver allows on/off operation and stepped flow adjustment without reaching the mains connection. Each receiver is paired to its remote frequency and includes mounting hardware according to Charles Austen’s current information.
Confirm that the exact pump listing includes or supports the receiver you intend to use; do not assume every BP package contains it.
Strong head from efficient models
BP8000, BP10000 and BP12000 combine increasing flow with 4.3, 5.8 and 6.2 m maximum head. Their published power figures make them attractive for features and circulation where pressure is needed, but the curve at working head must still be checked.
BP6000 is the entry model; because its current product summary lacks complete head and power data, verify the live specification before designing around it.
Installation and control
Use large-bore pipe, provide accessible isolation and mount any receiver in the approved dry location. Do not use remote switching as a reason to stop biological filter circulation for long periods.
Our advice: remote control is most valuable for a decorative stream or feature. A filter pump is usually best left running continuously at the flow the filter requires.

Frequently Asked Questions
Are BP pumps controllable?
They can be paired with the compatible Charles Austen remote receiver where specified.
Is the remote included?
Not necessarily. The manufacturer describes it as an optional accessory, so check the exact package.
Which BP model has the highest head here?
BP12000 has the highest published maximum head at 6.2 m.
Can I turn a BP filter pump off overnight?
Normally no. Biological filtration should generally receive continuous circulation.
Are BP pumps suitable for salt water?
Charles Austen describes the series as suitable for fresh and salt water, subject to the exact installation instructions.
Can the remote fine-tune a waterfall?
Yes. That is one of the clearest reasons to use the optional control system.
Why is BP6000 missing some figures?
The current product data supplied to the site does not publish complete head and power information, so confirm before specification.
Which is the lowest-power listed model with full data?
BP8000 is listed at 49 W.
Does maximum flow tell me what will reach the filter or waterfall?
No. Maximum flow is measured with little or no head. Lift, pipe length, fittings, hose diameter and connected equipment all reduce delivered flow.
Is maximum head the height at which I get full flow?
No. Maximum head is the shut-off end of the performance curve, where useful flow approaches zero.
Should I use the largest connection possible?
Usually yes. Generous, smooth pipework reduces friction and helps the pump deliver more water for the same electricity.
Can I reduce flow with a valve?
A valve can trim a water-pump output where the instructions allow, but a correctly sized pump or approved controller is normally more efficient than heavy throttling.
How often should I clean the pump?
Inspect it whenever flow falls and as part of routine pond maintenance. Keep the intake, rotor and impeller chamber clear without damaging seals or shafts.
Can you help size a BP pump?
Yes. Send us the required flow, vertical lift, pipe bore and length, major fittings and the equipment the pump will feed.
Why is my real flow lower than the model name?
Model names and maximum-flow figures do not include the resistance of a real installation. A flow test at the return is the best check after installation.
