The NovelBee 720GPH Manual Diaphragm Hand Bilge Pump is a self-priming, hand-operated diaphragm pump designed for quick water transfer and dependable emergency bilge duty on small boats.

Compact and built from durable ABS, this hand bilge pump delivers up to 720 gallons per hour and offers a reliable mechanical alternative when electrical bilge pumps are unavailable or fail. Its design prioritizes ease of use: a simple lever action, 1.3" inlet and outlet to fit common hoses, and lift/discharge capabilities suitable for most small-craft situations. Lightweight and corrosion-resistant, it’s intended as a primary transfer pump or as an emergency backup for yachts, dinghies, and workboats.

How much water can this pump move and how quickly?

The NovelBee pump has a peak capacity of roughly 720 gallons per hour under ideal conditions, giving you fast manual dewatering or transfer when needed. Real-world flow depends on suction lift, hose length, and discharge head.

• Rated flow: 720 GPH (theoretical peak)
• Max suction lift: 3 m (10 ft)
• Max discharge head: 4 m (13 ft)
• Best performance with short, straight hose runs

How easy is it to install and connect to my boat?

Installation is straightforward: the pump accepts 1.3" inlet and outlet ports and is compatible with 1.5" hose commonly used on boats, making plumbing fast and tool-light. Mounting can be done in a cockpit locker, bilge area, or near a scupper for rapid access during an emergency.

• Hose inlet/outlet diameter: 1.3" — fits 1.5" hose
• Simple screw or bracket mounting options
• No electricity required; manual lever operation
• Lightweight ABS body resists corrosion

What are the physical limits and materials I should know about?

The pump uses a durable ABS housing and a diaphragm mechanism intended for fresh or seawater dewatering and transfer. It is designed for manual operation, so consider the suction and discharge limits before planning continuous heavy-duty use.

• Body material: ABS plastic for weather and salt resistance
• Manual operation recommended for intermittent or emergency use
• Do not exceed 3 m suction lift or 4 m discharge head
• Hose fittings sized for standard small-craft plumbing

When should I choose this pump over an electric bilge pump?

This hand-driven pump is an excellent backup to an electric system or a primary option where electrical power isn’t available. It’s reliable, simple to repair, and gives you control when battery power is low or electronics fail.

• Ideal as an emergency or auxiliary bilge pump
• Useful on small boats, inflatables, tenders, and work skiffs
• No wiring means fewer failure modes in rough conditions
• Portable and easy to store when not in use

Who is this for? The NovelBee 720GPH Manual Diaphragm Hand Bilge Pump suits boat owners, deckhands, and mariners who want a lightweight, corrosion-resistant, and easy-to-install manual pump as either a primary transfer solution for simple tasks or as a dependable emergency backup to electrical bilge systems. If you need a compact, tool-friendly pump for dewatering, transferring water, or ensuring redundancy at sea, this pump is a practical and cost-effective choice.
