SHURFLO Piranha Pump Repair Kit — 94-620-00 Cartridge for 800/1100 GPH 12V Pumps, OEM Rebuild

The SHURFLO 94-620-00 pump repair and rebuild kit replaces the internal cartridge of Piranha 800/1100 12V pumps to restore flow and extend service life without swapping the entire pump.

If your Piranha livewell, aerator, or ballast pump has lost performance, this OEM SHURFLO replacement cartridge is built to bring it back to reliable operation quickly. The kit contains the components you need to rebuild the pump’s wet end, engineered for the Piranha Series’ 800 and 1100 GPH 12V models. It’s a practical alternative to full pump replacement, saving time and reducing maintenance costs while preserving the original housing and wiring already installed on your vessel.

How will this kit improve my pump’s performance?

Replacing the internal cartridge addresses worn impellers, seals, and bearings that cause reduced flow, noise, or intermittent operation. The rebuild restores the hydraulic geometry and sealing surfaces so the pump can move water at intended capacity again.

• Fresh cartridge and internal components designed for Piranha 800/1100 pumps
• Restores efficient water flow for livewells, bait tanks, and ballast transfer
• Reduces vibration and noise from worn internal parts
• OEM parts maintain original pump tolerances and fit
