ASC 175 Litre Stormwater Pit with D25VAMAG Pump
The ASC 175 litre Stormwater Pit and Pump System is your all-in-one answer for managing excess water, especially in areas prone to flooding. This system is designed as a ready-to-go solution, making it incredibly easy to set up and start using.
What It Is & How It Works
This system is a pre-plumbed unit, meaning it’s a “plug and play” solution right out of the box. It features a grated lid that efficiently collects both surface water and water flowing from underground pipes. Once collected, the integrated pump kicks in to move the excess water away.
Connecting it to your existing drainage is straightforward thanks to a 50mm threaded BSP brass fitting. It also includes a 40mm flap valve for smooth operation.
Ideal for Common Water Woes
This system is particularly effective for tackling water problems in various residential and light commercial settings, such as:
- Garage and driveway flooding
- Exterior edges of patios
- Areas around swimming pools
- Protecting cellars and basements
- Backyards with clay soil that struggle with drainage
The Powerful ASC D25VAMAG Pump
At the heart of this system is the ASC D25VAMAG pump. This robust pump is known for its reliability and features a vertical float, which is crucial for operating in small, confined spaces where a traditional float might get stuck. It’s capable of pumping water at flows up to 165 litres per minute and can achieve a vertical lift of up to 9 metres. For your convenience, it comes with a 10m Australian power plug.
Beyond just stormwater, the D25VAMAG pump is versatile. Its semi-vortex impeller allows it to handle suspended solids up to 15mm, significantly reducing the risk of blockages. This makes it suitable for a range of applications, including:
- Grey water pumping
- Sump emptying
- Septic effluent pumping
- General water transfer
- Pumping light industrial and factory waste systems
To ensure you get the best performance, always refer to the pump performance chart to match the necessary flow with your specific lift requirements.
Do you have a particular flooding issue in mind, or are you curious about the installation process? If you’re dealing with stormwater issues at your property, the ASC 175 litre Stormwater Pit and D25VAMAG Pump System offers a practical and effective solution. This isn’t just a pit; it’s a complete, pre-assembled package designed for efficient water collection and disposal.
