STR2/STN



The Grundfos STR2/STN twin impeller shower pumps are specifically designed to enhance the performance of low-pressure gravity feed shower installations. These pumps offer increased water flows at consistent pressure and temperature, ensuring a more enjoyable and satisfying shower experience. Here are some applications of the Grundfos STR2/STN twin impeller shower pumps:

1. Low-Pressure Gravity Feed Showers: The primary application of these pumps is to boost the water pressure in low-pressure gravity feed shower systems. If you have a gravity-fed shower that lacks adequate pressure, the STR2/STN pumps can be installed to improve the water flow and ensure a more powerful shower experience.

2. Residential Buildings: These pumps are suitable for installation in residential buildings that rely on gravity-fed water systems. Whether it's a single-family home or an apartment building, the STR2/STN pumps can be used to enhance the water pressure and improve the showering experience for all occupants.

3. Retrofitting Existing Showers: If you have an existing shower system that suffers from low water pressure, the STR2/STN pumps can be retrofitted to boost the performance. Instead of going through the hassle of replacing the entire shower system, installing these pumps can be a cost-effective solution to improve water flow and pressure.

4. Multi-Story Buildings: In multi-story buildings, water pressure tends to decrease as you move to higher floors due to gravity-fed systems. Installing the STR2/STN pumps can help overcome this problem by boosting the pressure specifically for shower installations on higher floors, ensuring consistent and satisfactory water flow.

5. Hotels and Hospitality Industry: The STR2/STN pumps can be utilized in hotels, resorts, and other hospitality establishments that prioritize guest comfort. By installing these pumps, they can offer guests better shower experiences with improved water pressure, regardless of the low-pressure gravity feed systems.

6. Commercial Buildings: Certain commercial buildings, such as gyms, spas, and health clubs, may have shower facilities for their customers. The STR2/STN pumps can be installed in these establishments to ensure an optimal showering experience and customer satisfaction.

In summary, the Grundfos STR2/STN twin impeller shower pumps are designed to enhance the performance of low-pressure gravity feed shower installations. They find applications in various residential and commercial settings, improving water flow and pressure to provide more enjoyable and consistent shower experiences.
