The Rhino 39030 gives you full macerator capability without a cord, a generator, or a 12V hookup. It runs on an 18V lithium-ion battery, grinds solid waste with VortexCore blade technology, and pumps at up to 12 GPM with a 10-foot vertical prime -- making it one of the most capable portable macerator kits available for RVers who dump away from traditional hookup stations.
Standard macerator pumps need 12V power from your tow vehicle or RV electrical system, or they need a 120V outlet nearby. The Camco 39030 breaks that dependency. The 18V lithium-ion battery system means you can set up a complete waste dump operation at remote campgrounds, residential septic cleanouts, or anywhere a cord won't reach -- with no adapters and no extension cables running across a parking lot.
VortexCore grinding creates a multi-blade vortex that liquefies solid waste and tissue before it enters the pump chamber, protecting the impeller and preventing clogs. The 12 GPM flow rate empties a standard 40-gallon black tank in roughly 3-4 minutes at full flow. The 10-foot vertical prime spec means the pump can lift waste against gravity -- useful when the pump sits below a raised RV and the dump inlet is at grade or above.
Multi-blade vortex liquefies solids and tissue before the pump chamber -- fewer clogs, faster flow.
No 12V tap, no extension cord, no generator. Run the full dump cycle on battery power.
Empties a typical 40-gallon black tank in approximately 3-4 minutes at full rated flow.
Lifts waste 10 feet vertically -- handles grade differentials and above-ground dump stations.
A macerator pump connects between your RV's black or gray tank outlet and the dump station or cleanout. Instead of relying on gravity flow through a 3-inch hose, it grinds waste into a fine slurry and pumps it under pressure through a standard garden-hose-diameter discharge line. That smaller hose is easier to handle, can run uphill, and stretches much farther than a rigid sewer hose.
Cordless operation specifically solves the problem of remote and primitive dumping locations. Many boondocking spots, residential properties, and agricultural dump points don't have electrical outlets anywhere near the dump area. With the 39030, you connect the inlet to your tank, connect the discharge hose to the cleanout or portable waste tank, and run the cycle on battery -- no adapters, no improvised power.
The 39030 is packaged as a complete kit. It includes the macerator pump unit, the 18V lithium-ion battery, a charger, inlet adapter fittings for standard RV tank outlets, and discharge hose connections. You are not buying just a pump head and sourcing parts separately. Verify kit contents on the product label before your first use to confirm all accessories are present.
Because the macerator pumps a liquefied slurry under pressure rather than relying on gravity, the discharge line can be a standard 3/4-inch or 1-inch garden hose rather than a 3-inch sewer hose. This lets you run discharge lines significantly farther -- often 50 to 100+ feet -- to reach a dump point that's inconveniently located. The 10-foot vertical prime spec means the outlet of the discharge line can be up to 10 feet higher than the pump, which covers most practical grade differences at campsites and residential cleanouts.
The Rhino macerator can also be used on the gray tank after dumping black. Running gray water through the pump after the black tank cycle helps flush the internal pump chamber and discharge line, reducing odor and residue buildup in the equipment.
The kit includes adapter fittings and connections, but the discharge garden hose itself may need to be sourced separately depending on your required run length. Use a dedicated hose for waste discharge -- do not repurpose a drinking water hose for this application. Label all waste-handling hoses clearly.
For campgrounds without on-site dump stations, the Rhino macerator works well paired with a portable waste tote tank (such as the Camco Rhino Tote series). Pump your tanks into the tote, then tow the tote to a dump station -- no need to move the RV.
