Lynvire 12V RV Macerator Pump — Portable 12 GPM Sewage Pump, 10 ft Lift, Quick-Release & Freshwater Rinse

The Lynvire 12V RV macerator pump is a portable, high-flow sewage pump that shreds and evacuates waste from 3" RV outlets fast and cleanly.

This compact macerator is engineered for RVs, boats, and campsites where reliable, sanitary waste removal matters. It pairs a powerful all-copper motor and dual stainless-steel cutters with a garden-hose rinse port and quick-release fittings so you can empty a typical 150 L black water tank in minutes. Built-in protections and simple plug-and-play power make it practical for weekend trips, seasonal maintenance, and emergency drain-out situations.

How fast and far can this pump move sewage?

The Lynvire macerator delivers up to 12 gallons per minute (about 45 LPM) and creates roughly 15 PSI, providing a vertical lift up to 10 feet and reliable suction at short lifts. That rate enables rapid tank emptying and long-distance discharge when needed.

• Flow: 12 GPM (45 LPM) — empties ~150 L in roughly 5 minutes
• Vertical lift: up to 10 feet (3.2 feet effective suction lift noted)
• Pressure output: ~15 PSI for steady discharge through hoses
• Designed for standard 3" RV waste outlets for direct connection

What features prevent clogs and make cleaning easier?

This pump uses dual four-blade stainless-steel cutters to macerate solids into very small particles, reducing blockages and smoothing flow through hoses. A dedicated freshwater rinse port and flow-control switch let you flush tank residue without disassembling connections.

• Dual 4-blade stainless cutters grind solids to ~1/16" particles
• Anti-clog, self-cleaning design reduces maintenance frequency
• 25 mm outlet plus garden-hose connector for rinse and debris clearing
• Quick-release fittings for fast hook-up and removal

How do I power and protect the pump during use?

Power is straightforward: the kit includes both a 7-foot cigarette-lighter cable and an 11.4-inch alligator clip cable for direct 12V battery hookup. The motor features thermal overload and dry-run protection to shut off automatically under stress, then restart after conditions normalize.

• Included power options: cigarette-lighter and alligator-clip cables
• Heavy-duty all-copper motor with precision bearings for efficiency
• Thermal overload and dry-run prevention for safe operation
• Low-noise design suited for roadside or campsite use

What basic care and safety steps should I follow?

Use the pump only with compatible 3" outlets and never run it dry or leave it powered while idle for long periods. If the pump halts for thermal reasons, resolve the cause before restarting; disconnect power to clear jams and avoid reaching into the unit while energized.

• Always connect freshwater rinse accessories when cleaning tanks
• Do not start the pump without liquid present or force restart after shutdown
• To clear debris, disconnect power and use the manual clearing port
• Drain residual water after use and protect from freezing in winter

Who is this for? The Lynvire 12V macerator pump is ideal for RV owners, boaters, mobile-home residents, and outdoor-service providers who need a compact, fast, and sanitary solution for black-water disposal. It suits users who value quick hook-up, minimal clogging, and built-in safety features, plus technicians who require a dependable pump for maintenance, winterization, or emergency tank emptying.
