Lynvire 12V RV Macerator Pump — Portable 12 GPM Waste Pump, 10 ft Lift, Garden-Hose Rinse

Lynvire's 12V RV macerator pump is a portable sewage pump that shreds and evacuates waste from 3" RV outlets at up to 12 GPM, with a garden-hose rinse and quick-release connections for fast, reliable dumping.

This compact macerator is engineered for RV owners, boaters and campers who need a faster, cleaner way to empty black and gray water tanks. It combines a dual-blade cutter, a high-flow 12 GPM motor, and multiple power-connection options so you can empty a typical 150 L tank in minutes and flush the line afterward without extra tools.

How quickly will this pump empty an RV holding tank?

The Lynvire macerator delivers up to 12 gallons per minute (approximately 45 LPM), designed to clear a 150 L tank in roughly five minutes under normal conditions. Its 15 PSI output and 10-foot vertical lift make it practical for most campsite or marina dump stations.

• Flow rate: 12 GPM (≈45 LPM)
• Typical empty time for 150 L tank: ~5 minutes
• Maximum vertical lift: 10 feet / 3.2 meters
• Pressure rating: 15 PSI for long-distance discharge

What prevents clogs and how does the rinse work?

Two stainless-steel four-blade cutters reduce solids to about 1/16-inch particles to dramatically lower clog risk. After dumping, a dedicated garden-hose discharge port with a flow-control switch lets you rinse the pump and hose to remove residue without disassembly.

• Dual 4-blade stainless cutters for fine maceration
• Particle size after cutting: ~1/16 inch
• 25 mm outlet plus garden-hose connector for fresh-water rinse
• Flow-control switch for controlled rinsing and reduced splatter

How durable and safe is the motor for repeated use?

The unit uses a heavy-duty all-copper motor with precision bearings for efficient, low-noise operation. Built-in thermal overload protection and dry-run prevention stop the pump if it overheats or runs without fluid, protecting components until conditions normalize.

• All-copper motor for long service life and efficient power use
• Thermal overload protection automatically cuts power if overheated
• Dry-run protection prevents damage when fluid is absent
• Quiet operation thanks to precision bearings

What power and connection options are included for immediate use?

The macerator ships ready for plug-and-play use with both a 7-foot cigarette lighter cable and an 11.4-inch alligator-clip cable, so you can hook to a vehicle or battery. It’s purpose-built for standard 3-inch RV waste outlets and works without extra adapters when used with compatible fittings.

• Included: 7 ft cigarette lighter cable and 11.4 in alligator-clip cable
• Designed for 3-inch RV waste outlets; quick-release fitting included
• Garden-hose discharge port for convenient rinsing
• Compact for storage in winterization kits or boat compartments

Who is this for: The Lynvire 12V macerator pump is aimed at RV owners, boaters, and campers who want faster, cleaner tank dumping without hauling the vehicle to a dump station or using bulky permanent plumbing. It's ideal for users with 3" waste outlets who need a portable, heavy-duty solution for seasonal use, winterization, or remote campsite servicing. Note: follow safety guidelines—do not run dry, avoid prolonged idle power, clear blockages only after disconnecting power, and protect the unit from freezing.
