ACCUCRAFT 12V RV Macerator Pump 12 GPM — Portable 3" Outlet Kit, 10 ft Lift & Anti‑Clog Blades

The ACCUCRAFT 12V RV Macerator Pump is a portable, self-priming waste transfer pump that chops solids and quickly evacuates RV, marine, or camper holding tanks through a standard 3" outlet.

Designed for campers, boaters and RV owners who want a faster, cleaner way to empty holding tanks, this all-in-one macerator kit includes everything needed to connect to a 3" RV outlet and pump sewage up to 10 feet away. With a compact 12-amp copper motor, dual spiral macerating blades and a fresh-water rinse port, it reduces clogging and keeps the hose path clearer than a simple gravity dump.

How fast and far can this pump move waste?

The pump delivers up to 12 gallons per minute and can lift waste vertically as high as 10 feet, with self-priming suction to about 3.2 feet. That combination clears a standard 150-liter sewage tank in minutes under typical conditions.

• Flow rate: 12 GPM for quick tank emptying
• Vertical lift: up to 10 feet for uphill discharge
• Self-priming suction: 3.2 feet to start pumping without manual siphon
• Compatible with standard 3" RV waste outlet for direct hookup

What prevents clogs and keeps the pump running reliably?

The macerator uses double 4-spiral blades that shred solids down to about 1/16" maximum, drastically lowering clog risk. An all-copper motor with built-in thermal overload protection increases durability and automatically pauses the unit if it overheats, restarting when cooled.

• Dual spiral blades: reduce particle size, cut clogs by up to 95%
• Copper motor: efficient, stable operation and lower noise
• Thermal overload protection: automatic shutoff and restart for safety
• Manual crushing feature: extra power on stubborn debris

How easy is setup, power connection, and cleaning?

The kit arrives ready to use: it fits standard 3" RV outlets and includes both a cigarette-lighter adapter and an alligator-clip cable for direct battery connection. A dedicated garden-hose style discharge port, fresh-water rinse and quick-release flush valve make post-use cleaning and maintenance straightforward.

• Complete kit: no extra accessories required for typical RV hookup
• Power options: 7 ft cigarette-lighter and 11.4 in alligator clip cable included
• Quick-release valve and rinse port: fast flushing after pumping
• 1" discharge port: accepts standard garden hose fittings for convenient routing

What are the technical specs and capacity details?

Operating at 12 volts DC and drawing roughly 12 amps, the pump connects to common RV electrical systems and battery banks. The inlet matches a 3" RV outlet while the discharge uses a 1" port; designed to empty typical recreational holding tanks rapidly.

• Voltage: 12 V DC; Current: 12 A
• Inlet size: 3" to fit standard RV waste outlets
• Outlet size: 1" garden-hose compatible discharge
• Performance: 12 GPM, 3.2 ft suction, 10 ft lift

Who is this for? The ACCUCRAFT macerator pump is made for RV and boat owners, campgrounds, mobile maintenance crews and anyone needing a portable, efficient way to move waste from holding tanks when gravity dumping isn’t practical. It suits users who want a quick-connect kit with strong maceration, reliable 12V operation, and easy flushing to keep the system clean between uses. If you value speed, fewer clogs and simple hookups without added accessories, this pump meets those needs.
