SHURflo 3200 Macerator: Pump Models & OEM Repair Parts
The SHURflo 3200 macerator is a 12-volt pump for transferring waste from an RV holding tank to an approved dump location. The 3200-001 and 3200-201 have the same basic connection arrangement but different rated flow and electrical loads. When replacing the complete pump or repairing its cutting and impeller sections, match the full number on the existing motor label.

The flow ratings describe the manufacturer-specified model performance. Actual emptying speed depends on fluid, hose length, lift and the discharge arrangement. A pump with matching port sizes is not automatically the correct electrical or mounting replacement for another model.

These four SHURflo parts are listed for both 3200-001 and the 3200-200/201 RV macerator family. Identify the failed component by its factory drawing number before ordering.
| Drawing number | Factory replacement kit | Component |
|---|---|---|
| 1 | 94-571-00 | Flexible impeller repair kit |
| 2 | 94-570-00 | Impeller housing kit |
| 3 | 94-570-02 | Macerator blade kit |
| 4 | 94-570-04 | Motor-side lip-seal kit |
1 — Flexible impeller
Moves the macerated waste through the discharge side of the pump.
2 — Impeller housing
Surrounds the flexible impeller and forms its pumping chamber.
3 — Cutting blades
Break up suitable waste at the inlet side before it reaches the impeller.
4 — Shaft lip seal
Helps keep pumped liquid away from the motor-side shaft area.

Safe operating and maintenance checks
SHURflo specifies a momentary switch so the operator can stop the pump when the tank empties. Do not continue running a dry pump for more than 15–20 seconds. The pump has a run-dry-capable design but excessive dry operation can damage the impeller and housing. It is intended for normal RV holding-tank waste, not hard objects, rags or sanitary products.
- Disconnect the 12-volt supply before opening the pump or removing its wiring. Use a fuse and wiring sized to the motor label and the manufacturer's installation chart.
- Close the upstream holding-tank shutoff valve and isolate the discharge line before dismantling the pump. Use suitable gloves and sanitation procedures.
- Compare the complete pump number and factory drawing callout before choosing an impeller, housing, blade or seal kit.
- Flush the tank and pump with clean water after use as directed by the manufacturer, and confirm the system is leak-free after service.
