When Efficiency Matters
Efficiency isn’t just about saving power — it’s about creating a pool that runs quietly, smoothly, and effortlessly, so you can simply enjoy it.
Frequently Asked Questions
How quiet is the pump during operation?
Extremely quiet — as low as 36 dB at low speed, making it one of the quietest variable-speed pumps available.
What energy savings can I expect?
Inverter control can reduce power use by up to 80% compared with single-speed pumps, depending on usage and speed settings.
What is the annual energy consumption?
Approximately 492 kWh per year, based on a daily run time of 6.00 hours. For a quick cost guide, multiply 492 by your electricity price (e.g., at 60 c/kWh that’s about $0.81/day or $25/month). Actual results vary with tariffs, hydraulics, and selected RPM settings.
Is it compatible with saltwater pools?
Yes, it’s suitable for pools with salinity up to 3,500 ppm.
Can it replace my existing pool pump without re-plumbing?
Yes. It’s retrofit-ready and directly replaces most Astral Pool CTX, E, FX, and XP-Series pumps using the same 40/50 mm unions.
Does it have Wi-Fi and app control?
Yes. The built-in Wi-Fi allows you to control, schedule, and monitor performance through the Madimack app on your smartphone.
What does Skimmer Mode do?
It automatically activates surface-skimming cycles to remove leaves and floating debris, keeping the waterline clear.
How many timers can I program?
Up to four independent on/off cycles can be scheduled each day.
What happens with loss of prime or low flow?
The built-in protection automatically shuts the pump down to prevent damage.
Can it connect to a pool automation system?
Yes. It supports external digital input and RS485 communication for integration with compatible control systems.
Is it suitable for commercial pools?
It can be used in commercial settings; however, warranty coverage is two years for commercial installation and five years for residential use.
Does it need to be installed under cover?
It’s weather-resistant (IP55) but should be installed in a ventilated area, ideally shaded and protected from direct rain or sun for best longevity.
What routine maintenance is required?
Periodically empty and rinse the strainer basket, check the lid O-ring, and ensure the inlet and outlet are clear of debris.
Does the app show energy consumption?
Yes. The Active Energy Monitor provides real-time and historical energy usage data.
