Grundfos Shower Pumps Databooklet

Grundfos STN-1.5 B is a premium brass shower pump with universal head and two impellers, designed and manufactured to the highest standards. 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. This shower pump ensures high performance, long durability and is suitable for domestic, commercial or light industrial use to boost shower pressure up to 4 bar. The shower pump is used for boosting both hot and cold water to single showers, multiple showers or whole house boosting where the outlets are above or below the cold-water tank.

The shower pump is a heavy-duty pump that relies upon brass impellers and machined brass stamps for improved durability and high performance. The pump is supplied with a flexible and braided stainless steel connection hose making it resistant to corrosion. Anti-vibration feet and long-life silicon carbide seals reduce the operating noise to 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.
