09-1052S-9 Johnson Pump F3B & TA3P10 Macerator Impeller | Genuine OEM Marine Part

🔧 Product Description

Aftermarket F3B / TA3P10 Nitrile Macerator Impeller - Replaces SPX Johnson 09-1052S-9

Compact six-blade nitrile impeller for Johnson TA3P10/F3P10 macerator and selected F3B utility pumps. SPX lists no Jabsco direct replacement, so dimensional aftermarket crossovers must retain the 45.2 × 12.8 mm single-flat configuration.

⚙️ Key Features

• Material: nitrile, oil and waste-fluid resistant
• Outside diameter: 45.2 mm / 1.78 in
• Width: 12.8 mm / 0.50 in

🚤 Compatibility

Commonly used on

• SPX Johnson TA3P10 macerator pumps

Application Details

• Pump / Service Type: Macerator, waste, oil and compatible utility-pumping service
• Identification: Confirm 45.2 × 12.8 mm size, 8 mm single-flat drive and six blades.
• Always compare the removed impeller or pump against the listed dimensions, drive style, material and housing depth before installation.

🔌 Function

The flexible vanes form expanding chambers on the inlet side and contracting chambers on the discharge side. This produces self-priming suction and moves cooling water or other compatible fluids through the pump.

⚠️ Common Signs of Failure

• Reduced flow or inability to prime
• Engine overheating or weak cooling-water discharge
• Pulsing flow, cavitation or unusual pump noise
• Vanes are cracked, hardened, flattened or missing
• Hub has slipped, corroded or loosened from the rubber body
• Impeller has been damaged by dry running, debris or incompatible fluid
