Grundfos SCALA1 5-55 — 99631754 Water Booster Pump 115V
Grundfos SCALA1 5-55 (99631754) — 115V High-Head Booster Pump
The Grundfos SCALA1 5-55 at 115V brings full smart booster pumping performance to households powered by standard 115V circuits. It integrates pump, motor, pressure sensor, control electronics, and a small buffer tank in a fully sealed package, offering up to ~5 to 55 GPM and strong head capacity. Bluetooth connectivity, diagnostics, and protection features make it an intelligent pick for pressure boosting. )
Key Features & Benefits
- 115V motor option for circuits without 230V availability
- Integrated, self-priming booster system with minimal external parts
- High performance: up to ~55 GPM/45 m head (depending on conditions)
- Bluetooth-enabled control and monitoring via Grundfos GO
- Protection built in: dry-run, lock-up, overload detection
- Quiet operation (~55 dB) in sealed IP6X housing
Applications
- Residential pressure boosting on 115V supply
- Tank-to-home setups and weak municipal pressure cases
- Low-to-mid elevation irrigation circuits
- Backup or remote installations where 230V isn't available

Common Questions
Q: Why 115V vs 230V version?
A: Use this variant when your site only has 115V supply or to avoid rewiring to 230V.
Q: Can it maintain pressure with multiple taps open?
A: Yes — its variable-speed control adjusts output to sustain pressure under varying loads.
Q: What protections are included?
A: Dry-run, lock-up, overload, diagnostics, and motor protection are built in.
Q: Is 115V less efficient?
A: Efficiency differences are minimal; performance per curve remains largely the same as long as application conditions are within spec.
SCALA1 5-55 at 115V delivers high head and smart booster performance for systems constrained to standard voltage supply.
