The Diaphragm Ocean Tech Waste Pump 12V 32 L/min is a compact, rugged solution designed for modern marine wastewater needs. Built to fit where space is tight and reliability matters, this Italian-made pump delivers steady, high-flow performance with minimal hassle.

Why this pump stands out

• Compact, flexible installation: Designed to fit in small bilges, shower pits, and Matromarine waste tanks without crowding your layout. Its 360° rotational pump body makes routing hoses easy in awkward spaces.
• Powerful yet efficient: Operates at 12V with a modest 4.5A draw, delivering up to 32 L/min while keeping energy use low and battery strain minimal.
• Reliable dry-running and air/water handling: No filters required and built to run dry. It effortlessly handles mixtures of air and water, which reduces blockages and simplifies maintenance on longer trips.
• Backflow protection and durability: Features double non-return valves to prevent backflow, protecting your system and keeping wastewater where it belongs.
• Quiet, low-maintenance operation: Meet ISO 8846 and EN55014 standards for safer, quieter performance — ideal for live-aboard comfort and smaller vessels.
• Versatile compatibility: 38 mm diameter hose tail ensures straightforward connections to common waste and gray-water lines on boats and leisure craft.
• A practical replacement option: Serves as a modern alternative to popular marine waste pumps (compatible with configurations like Jabsco 50890-1000/1), offering long-term reliability in a compact package.

Who needs this pump

• Boat owners and sailors looking to upgrade or replace a compact bilge or waste-water pump in tight spaces.
• Owners of small to mid-sized leisure crafts who want a quiet, energy-efficient solution for gray water and wastewater management.
• Installers seeking a robust, maintenance-friendly pump that can be mounted in confined spaces such as shower drains or dedicated waste-tank areas on boats.

Use cases and practical insights

• Bilge and shower drain integration: Ideal for small boats where space is precious. Its slim profile and 360° orientation simplify installation behind bulkheads or under compact sinks.
• Wastewater management: Connect to the Matromarine waste-water system or equivalent tanks to maintain steady flow without frequent service calls.
• Air-water mixture tolerance: When a line briefly contains air or condensate, the pump keeps moving rather than stalling, reducing downtime during trips.
• Energy-conscious boating: Low power draw helps extend battery life on overnight passages, while quiet operation minimizes noise in cabins and cockpits.

Installation tips for best results

• Plan a route with a direct, short hose run to reduce head loss and noise. The 38 mm hose tail is a common fit for many marine lines.
• Mount the pump in a location accessible for inspection, yet protected from splashes and direct exposure to salt spray when possible.
• Ensure secure electrical connections and adequate fuse protection on a 12V circuit to safeguard against surges.
• Test before finalizing the fit: run the system dry to confirm the rotation and check for leaks, then introduce wastewater to verify proper flow and valve operation.

Upgrade to the Diaphragm Ocean Tech Waste Pump 12V 32 L/min and experience effortless, compact wastewater management on your vessel. Its combination of dry-running capability, 360° flexibility, and quiet, efficient performance makes it a practical, long-term solution for boats and other small-space applications.
