【Powerful Grinding & Fast Discharge】 Driven by a high-performance 12V DC motor, this macerator pump features dual 2-blade stainless steel cutters that smash waste and toilet paper into fine particles instantly. With a 12 GPM (45 LPM) high flow rate, it empties a 40-gallon black water tank in less than 5 minutes—no more long queues at the campsite dump station! 【Impressive 3m Lift & 100m Horizontal Run】 Engineered with a 1m (3.2ft) self-priming suction lift, a 3m (10ft) vertical head, and a massive 100m (320ft) horizontal discharge range. The powerful water thrust allows you to pump waste effortlessly over long distances or uphill directly into your residential toilet or sewer clean-out from your driveway. 【Mess‑Free & Effortless Dumping】 Ditch bulky, messy 3‑inch sewer hoses for good. This heavy‑duty 12V macerator pump and caravan waste pump grinds solids finely so sewage flows seamlessly through a standard 1" discharge hose. It makes emptying your motorhome and caravan holding tanks a clean, hassle‑free, and discreet experience. 【Universal Fit & Easy Installation】 Features a universal RV bayonet fitting that easily connects to your motorhome's standard waste outlet in seconds. The dual-use design lets you flush the black water tank first, then clean the pump and hose using grey water. 【Dual Protection & Electrical Safety】 Built-in advanced Thermal Overload Protection and Overcurrent Protection systems. The pump will automatically shut off if it detects overheating or excessive current, effectively preventing motor burnout and ensuring maximum safety during operation. (Note: To ensure a long lifespan, please do not run the pump dry; ensure liquid is flowing before turning it on).
