Pentair Hydraulic Kit | Boost-Rite & HydroBoost Booster Pumps | ZBR39330

Description

The Pentair Hydraulic Kit (ZBR39330) is the OEM replacement hydraulic assembly for the Boost-Rite™ and HydroBoost booster pump lines.

⚠️ IMPORTANT: KIT LISTING — MULTIPLE COMPONENTS INCLUDED
This listing is a kit, not a single component. All hydraulic kit components are included as a set. Order one kit per pump being serviced.

The hydraulic kit contains the internal hydraulic components required to restore full pump function on the Boost-Rite™ and HydroBoost booster pumps. Booster pumps supply dedicated high-pressure water flow to pressure-side pool cleaners; when hydraulic components wear, the pump loses the pressure output needed to drive the cleaner effectively. Replacing the complete hydraulic kit restores factory flow performance without replacing the entire pump assembly.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Pro Tip

Before ordering, confirm your booster pump model — the Boost-Rite™ and HydroBoost are distinct pump lines that share this hydraulic kit. The model name is typically printed on the pump label. If the label is worn, check your original installation paperwork or the pump’s wiring compartment cover for a model reference sticker.
