The Grundfos Amazon STN-1.5 Bar is a premium brass shower pump featuring a universal head and twin impellers, engineered to the highest standards for reliable performance and long-lasting durability.
Designed to boost both hot and cold water supplies, this versatile pump is suitable for single showers, multiple outlets, or whole-house systems. It can be installed where outlets are positioned either above or below the cold water tank, making it a flexible solution for a wide range of applications. Delivering pressures of up to 4 bar, it is suitable for domestic, commercial, and light industrial use.
As a continuously rated regenerative pump, the STN-1.5 Bar is highly effective at overcoming air pockets within the system. This makes it ideal for installations with complex pipework, including multiple bends and elbows, ensuring smooth and consistent performance.
Constructed from heavy-duty brass, including brass impellers and precision-machined components, the pump provides exceptional durability and high performance. It is supplied with stainless steel, flexible braided connection hoses for enhanced corrosion resistance and long-term reliability.
For quieter operation, the pump is fitted with anti-vibration feet and long-life silicon carbide seals, helping to minimise noise levels. Integrated thermal protection automatically shuts off the motor in the event of overheating, providing added safety and peace of mind.
