Why this macerator pump stands out

When space, reliability, and efficiency matter, the TMC Macerator Pump 24V delivers. Its macerator action breaks down solids in-line, enabling waste to be pumped through standard hoses with less risk of clogs. The self-priming design removes the hassle of priming in cramped compartments or on the move, so you can start pumping quickly after installation. Built for 24V DC operation, it integrates smoothly with onboard power systems in caravans, motorhomes, and boats, offering consistent performance where you need it most.

• High-flow, low-fuss operation: up to 44 L/min with a 5 m maximum head for efficient tank emptying and flexible routing.
• Self-priming efficiency: reliable startup in varying orientations and tight spaces, ideal for mobile installations.
• Macerator capability: solids are ground into slurry to pass through hoses more easily, reducing maintenance interruptions.
• Inline, space-conscious design: engineered for compact installation in limited compartments without sacrificing performance.
• Rugged, mobile-ready build: designed to withstand the vibrations and movement common in caravans, boats, and motorhomes.

Who benefits and practical use cases

This pump is ideal for anyone managing a holding tank on a trailer, motorhome, caravan, or boat. If you rely on a dependable, ready-to-use solution to evacuate waste quickly and with minimal fuss, the TMC Macerator Pump 24V is built for that scenario. Its 24V compatibility makes it a natural fit for existing mobile electrical setups, reducing the need for additional power solutions while delivering steady, predictable performance.

Installation and ongoing care

Install as an inline pump between the holding tank and the discharge line to maximize efficiency and minimize hose complexity. Ensure proper orientation and secure mounting to tolerate movement. For best results, keep intake paths clear of debris and follow standard maintenance routines typical for macerator pumps in mobile environments. This approach helps maintain flow consistency and extends the life of the pump, keeping your waste-management system running smoothly on every trip.
