Base per pompa Sta-Rite — 0,55 kW (RC478P)

Pump base / mounting foot for the Sta-Rite HD pump range, rated for the 0.55 kW motor block. The base holds the motor + seal plate assembly at the correct height above the pool-room floor and dampens motor vibration so the pump runs quiet and the base bolts don’t work loose over time.

Order the matching kW/phase variant — the small (0.55 kW) motor block sits on a different mounting boss height and bolt pattern than the medium (1.10–1.50 kW) or large (2.20 kW) blocks. Getting the wrong base version forces the seal plate off-axis and shortens the mechanical seal life drastically.

Includes the vibration-isolating rubber pads at the mounting points. Genuine Sta-Rite / Pentair part — machined bolt boss lines up straight with the OEM motor. Replace when the base is cracked, when the vibration pads have hardened, or when a pump swap goes from one motor family to another.
