12V macerator pump designed for RV and marine sanitation waste evacuation, with dual-cut stainless blade design, flexible impeller pump, 13 GPM typical flow, and 1-1/2" inlet x 1" outlet connections.
The SHURflo 3200-001 is a 12V macerator pump designed for sanitation waste and fish box evacuation in compatible RV and marine systems. It helps grind and transfer waste from holding tanks through a discharge hose using a flexible impeller pump and stainless steel dual-cut blade design.
This pump is commonly used for RV black water and gray water waste evacuation where the plumbing, voltage, fuse protection, and port sizes match the installation. Its sealed motor construction, thermal protection, and ignition-protected design make it suitable for harsh RV and marine environments when installed correctly.
Designed for RV and marine sanitation waste transfer applications
Stainless steel blade design helps grind waste before discharge
Typical flow rating up to 13 gallons per minute at 0 ft head
Runs on compatible 12-volt RV and marine electrical systems
This pump is not a universal replacement for every RV or marine macerator pump. Verify your existing pump model, voltage, inlet/outlet sizes, wiring, fuse rating, mounting space, and plumbing layout before ordering. The SHURflo 3200-001 is listed with a 1-1/2" hose barb / 1-1/2" male NPT inlet and a 1" hose barb outlet. It is intended for intermittent-duty waste evacuation and is not listed for potable water use.
Before Starting: Disconnect 12V power and confirm the RV waste system is drained, flushed, depressurized, and safe to service. Wear appropriate protective equipment when working around black tank, gray tank, sewage, or fish box plumbing. Basic Installation Steps: 1. Confirm Fitment: Compare the existing pump model, voltage, inlet size, outlet size, fuse rating, wiring, hose style, and mounting space. 2. Disconnect Power: Turn off the 12V pump circuit before removing wiring or plumbing. 3. Prepare the Waste System: Drain and rinse tanks as thoroughly as possible before removing the old pump. 4. Remove Existing Pump: Disconnect inlet/outlet hoses, wiring, and mounting hardware from the old pump. 5. Mount Near the Tank: Install the pump as close to the holding tank as practical for best performance and pump life. 6. Connect Plumbing: Attach the 1-1/2" inlet and 1" outlet using compatible sanitation-rated hose, fittings, clamps, and adapters as needed. 7. Wire Correctly: Connect to a separate, properly fused 12V DC circuit using the correct fuse size and wiring practices. 8. Use a Momentary Switch: A properly sized momentary switch is recommended so the operator can stop the pump when the tank is empty. 9. Test Operation: Run the pump with liquid present, checking for leaks, flow, abnormal noise, overheating, or electrical issues.
Package Contents: • 1 SHURflo 3200-001 12V macerator pump • Integrated dual-cut blade and flexible impeller pump assembly • Motor and pump body components as supplied by manufacturer NOT Included — May Also Need: • 1-1/2" inlet hose or compatible inlet fitting • 1" discharge hose • Hose clamps • Wiring, momentary switch, fuse holder, or circuit protection components • Sanitation fittings, adapters, valves, or sealant • Tank fittings or plumbing components not supplied with the pump • Installation tools or waste system service supplies This listing is for the macerator pump only unless otherwise stated. Confirm required hoses, fittings, wiring, switch, and installation supplies before ordering.
To confirm compatibility before ordering, have the following ready: • Existing pump brand and part number • Photos of the existing pump label and plumbing connections • Voltage and fuse/circuit information • Inlet and outlet hose measurements • Whether the inlet uses hose barb, threaded connection, or adapters • Available mounting space and pump orientation • RV or boat year, make, model, and waste system layout if available Why this matters: Macerator pumps can look similar while using different port sizes, fuse ratings, outlet orientations, wiring requirements, mounting dimensions, and plumbing adapters.
Match this pump by part number, voltage, inlet size, outlet size, amperage/fuse requirements, duty cycle, plumbing layout, and available mounting space. Do not select by voltage or general appearance alone.
If pump issues continue after installation, check power supply, fuse size, wiring, switch, valves, hose routing, tank outlet condition, priming distance, and plumbing compatibility before replacing additional components.
This pump is intended for compatible RV and marine waste evacuation applications only. It is not for drinking water or potable freshwater supply. Do not use with gasoline, fuel, solvents, chemicals, hard objects, rags, feminine hygiene products, or other materials that can damage or jam the pump. Do not operate against a closed valve and do not intentionally run dry for extended periods. Always disconnect power before servicing and follow proper sanitation procedures when working with sewage, black tank, gray tank, or fish box plumbing.
