Replacement impeller service kit for compatible SHURflo 3200 Series RV and marine macerator pumps, including the replacement impeller and gasket needed for pump-head service.
The SHURflo 94-571-00 macerator impeller kit is designed to service compatible SHURflo 3200 Series macerator pumps used in RV and marine waste evacuation systems. If the pump motor runs but waste flow is weak, inconsistent, or reduced, a worn or damaged impeller may be one of the parts to inspect.
This kit includes the replacement impeller and gasket for pump-head service. It is intended for repairing compatible SHURflo macerator pumps rather than replacing the full pump assembly, helping restore pumping performance when the motor, wiring, housing, cutter, and other components are still serviceable.

For compatible waste evacuation macerator pump systems
This kit is designed for compatible SHURflo 3200 Series macerator pumps. It is not a universal impeller kit for all RV macerator pumps, marine macerator pumps, freshwater pumps, or other SHURflo pump models. Verify the pump brand, pump model/series, part number, pump head style, and existing failure symptoms before ordering. If the motor is seized, wiring is damaged, housing is cracked, cutter is jammed, or seals are leaking, additional parts or full pump replacement may be required.
Before Starting: Disconnect 12V power to the pump and make sure the waste system is drained, flushed, depressurized, and safe to service. Wear gloves and follow sanitation procedures when working around macerator pumps or waste plumbing. Basic Service Steps: 1. Confirm Pump Model: Verify the existing pump is a compatible SHURflo 3200 Series macerator pump before disassembly. 2. Disconnect Power: Turn off power at the pump circuit and confirm the pump cannot activate accidentally. 3. Prepare the Waste System: Drain and rinse the tank and pump plumbing as thoroughly as possible. 4. Access Pump Head: Remove the pump from the system or access the pump head according to the pump service instructions. 5. Inspect Components: Check the impeller, gasket surface, cutter area, housing, seals, and motor shaft for wear, debris, cracking, or damage. 6. Replace Impeller and Gasket: Install the new impeller and gasket using the correct orientation and service procedure for the pump. 7. Reassemble Carefully: Reinstall the pump head evenly without pinching or misaligning the gasket. 8. Reconnect Plumbing: Reattach hoses and clamps, checking for proper fit and seal condition. 9. Test with Liquid Present: Restore power and test the pump briefly with water/waste liquid present. Check for leaks, flow, vibration, and abnormal noise.
Package Contents: • 1 replacement impeller • 1 replacement gasket NOT Included — May Also Need: • Complete macerator pump • Pump motor • Pump housing or pump head assembly • Cutter blade or cutter plate, unless separately supplied • Shaft seal or additional O-rings, unless separately supplied • Hose clamps, fittings, wiring, or switch components • Sanitation supplies, gloves, or cleaning materials • Installation/service tools This listing is for the impeller repair kit only unless otherwise stated. Confirm whether additional pump parts are required before ordering.
To confirm compatibility before ordering, have the following ready: • Existing pump brand and model number • Photo of the pump label • Pump series, such as SHURflo 3200 Series • Photos of the pump head and existing impeller if already disassembled • Description of the failure symptom, such as weak flow, no flow, leak, jam, or blown fuse • Whether the motor runs normally • Whether the pump housing, cutter area, or shaft seal is damaged Why this matters: A replacement impeller can help with worn-impeller flow problems, but it will not fix a failed motor, damaged wiring, cracked housing, jammed cutter, or incorrect pump installation.
Match this kit by SHURflo pump series, pump model, pump-head style, included components, and failure symptoms. Do not select by appearance alone.
If pump performance does not improve after replacing the impeller, inspect voltage, wiring, valves, hose routing, cutter condition, housing wear, shaft seal, and tank outlet condition before replacing additional parts.
This kit is for compatible SHURflo macerator waste pump service only. Always disconnect power before disassembly and follow proper sanitation procedures when working with black tank, gray tank, sewage, or marine waste plumbing. Do not service the pump while connected to power, do not run the pump dry for extended periods, and do not use this kit for potable water pumps or non-compatible pump models.
