Grundfos SCALA1 is a fully integrated, self-priming, fixed speed water presure booster pump designed for a variety of applications, including shallow well, boosting from tanks, from city mains, etc. The pump features Bluetooth connectivity and can be controlled via Grundfos Go app, which allows to set pump run schedule, run diagnostics and much more. SCALA1 now features a twin mode (with a separately sold piping kit), which allows to utilize both pumps at once (for added output) or in stand-by mode (as a backup). The all-new dual 24v external input connections allow to engage/disengage the pump using an alarm or a float/level/sensor switch.
Features:
Fixed speed motor
Bluetooth enabled, works with Grundfos Go app for custom run schedule, diagnostics and more
Twin mode (duty assist or duty stand-by) - enables use of two pumps (with 99725168 kit) for increased ouput or backup

While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
