Grundfos Shower Pumps Databooklet

Grundfos STR2-1.5 C is a regenerative shower pump with positive head and two impellers. This pump is the result of extensive research and development, resulting in a high-performance pump at an affordable price. The shower pump is continuously rated as a regenerative pump making it equipped to overcome air pockets and ideal where the plumbing route includes multiple bends and elbows. The shower pump is used for boosting hot and cold water to single showers or simple bathroom suites where the outlets are below the cold-water tank.

This high-performance composite shower pump has an innovative design, and by incorporating a low-speed induction motor, it improves durability and ensures a long life. This design ensures minimal turbulence in the pump head. The pump is supplied with a flexible and braided stainless steel connection hose making it resistant to corrosion. Anti-vibration feet, long-life carbon graphite and high-density ceramic seals ensure that the operating noise is held at a minimum. The shower pump has built-in thermal protection, which immediately stops the pump motor if it overheats.

The shower pump is a WRAS-approved product and as such the whole product has undergone and passed extensive mechanical and water quality testing. Additionally, this pump is a regenerative pump making it equipped to overcome air pockets.
