90L Groundwater / Dewatering Pump System

Ideal Pump System for Basements, Cellars & Flood-Prone Areas

Keep your basement dry and protected with our 90L Groundwater & Dewatering Pump System - a compact, fully automatic solution designed specifically for residential basements and cellars. This complete pump package is perfect for removing groundwater or flood water where gravity drainage isn’t possible.

Reliable, powerful, and easy to install, this system is trusted by professionals but simple enough for homeowners and builders alike.

Why Choose This System?

✅ Compact & Space-Saving
The 90L sump chamber is designed to fit neatly into tight spaces, requiring minimal groundwork.
Chamber size: 460mm (D) x 560mm (H)

✅ Powerful Performance
Capable of pumping up to 260 litres per minute with a vertical lift of 7.5 metres, making it ideal for domestic basement environments.

✅ Fully Automatic Operation
The pump switches on only when water levels rise and turns off automatically once cleared - efficient, reliable, and worry-free.

✅ More Reliable Float Switch
Fitted with a vertical arm-style float switch, which is far more dependable than traditional cable floats and less prone to failure.

✅ Prevents Backflow
A built-in non-return valve ensures water cannot flow back into the chamber once pumped away.

✅ High-Quality Pipework
Supplied with 1½” Class C high-pressure PVC pipework, improving flow rates, reducing vibration, and outperforming standard waste or MDPE pipe.

✅ Built to Last
Manufactured from high-quality moulded polyethylene and supplied with an anti-flotation device to keep the chamber secure even in high groundwater conditions.
