The Grundfos STN-2.0 B is a premium brass shower pump featuring a universal head and twin impellers, engineered to the highest standards for powerful performance and long-lasting reliability.
Designed to boost either hot or 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 above or below the cold water tank, offering flexibility across a wide range of applications. Delivering water pressure of up to 4 bar, it is ideal for domestic, commercial, and light industrial use.
As a continuously rated regenerative pump, the STN-2.0 B is highly effective at overcoming air pockets within the system. This makes it particularly suitable for installations with complex pipework, including multiple bends and elbows, ensuring consistent and reliable 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, offering excellent 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.
Fully WRAS approved, the STN-2.0 B has undergone extensive mechanical and water quality testing, ensuring compliance with industry standards and dependable performance.
