Product Description

Pallas PWG APT-120 Pressure Storage Tank – 120 Litres (1" BSP with Base)

The Pallas PWG APT-120 is a 120 litre vertical pressure storage tank that holds your water pressure at a set level and stops your pump starting every time a tap is opened. It is ideal for larger homes and borehole systems that need more reserve but have limited floor space, thanks to its slim 39 cm diameter.

Water is stored between a heavy-duty butyl diaphragm and an FDA grade polypropylene liner, so it never touches the steel shell. The pressurised air chamber above the diaphragm pushes stored water back into the system, cutting the number of pump starts, saving energy and extending pump life.

The APT-120 has a total volume of 120 litres. Usable (drawdown) volume depends on your pump's pressure switch settings and is typically around 30–50% of total volume, so expect approximately 36–60 litres between pump starts.

The APT-120 suits larger homes and borehole systems. At 39 cm wide it fits where the wider APT-200 won't, but it is 114.8 cm tall, so check headroom. For high-demand or light commercial systems, consider the APT-200. Final sizing depends on your pump's flow rate and pressure settings, so call us with your pump details if you are unsure.
