The Grundfos STP-1.5 B is a premium brass shower pump featuring a positive head design and twin impellers, engineered to deliver reliable performance and long-lasting durability. Manufactured to the highest standards, it provides an ideal solution for boosting water pressure in a wide range of applications.
Designed for continuous operation, this regenerative pump is highly effective at overcoming air pockets within the system, making it particularly suitable for installations with complex pipework, including multiple bends and elbows. Delivering water pressure of up to 4 bar, it is suitable for domestic, commercial, and light industrial use.
The STP-1.5 B is designed to boost both hot and cold water supplies to single showers, multiple outlets, or whole-house systems, where outlets are positioned below the cold water tank.
Constructed from heavy-duty brass, including brass impellers and precision-machined components, the pump ensures exceptional strength and 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.
Fully WRAS approved, the STP-1.5 B has undergone extensive mechanical and water quality testing, ensuring compliance with industry standards and dependable performance.
