MAXZONE Submersible Bilge Pump 12V 750 GPH

Flow Rate: 750 GPH. Voltage: 12 VDC. Head: 13 ft (4 m). Outlet: 3/4″ (19 mm). Typical uses include hydraulic systems fed with cold water and lines fed by gravity or pressure. Best for small boats or ponds with modest drainage needs where a compact unit is preferred.
Who it’s best for: boaters needing a small, straightforward pump for limited bilge space or pond maintenance without automatic features. Why selected: compact size and sufficient flow for light-duty bilge or water transfer tasks.
Caution: manual operation means no auto-start; ensure you activate it before heavy water accumulation to avoid delays.
MAXZONE Automatic Submersible Bilge Pump 12V 1100 GPH

Flow Rate: 1100 GPH. Volt: 12V. Current: 3.8A. Head: 3.0 m. Outlet: 1-1/8″ (29 mm). Includes a built-in float switch, eliminating the need for a separate float. Best for boats needing reliable automatic switching with relatively compact height.
Who it’s best for: users who want automatic bilge control with a small footprint. Why selected: integrated float switch reduces wiring complexity and power consumption for unattended operation.
Caution: some installations may require precise height alignment for optimal auto-activation. Check your bilge depth to ensure the switch engages reliably.
MAXZONE 1100 GPH Submersible 12V Non-Automatic

Flow Rate: 1100 GPH. Voltage: 12 VDC. Head: 13 ft (4 m). Outlet: 1-1/8″ (29 mm). Typical uses include hydraulic systems fed with cold water—fed by gravity or pressure. Best for situations where manual control is acceptable and a high flow is needed in a compact form.
Who it’s best for: those who prefer manual operation or back-up pump configurations. Why selected: higher-flow option without automatic features offers straightforward reliability when you want direct control.
Caution: no built-in float means you must provide a separate control plan to prevent overflow in unattended applications.

Buying Guide: Small Electric Bilge Pumps — What To Consider
- Flow rate vs. bilge size: Larger bilges benefit from higher GPH; smaller bilges can use 750–1100 GPH without overworking the pump.
- Automatic vs. manual operation: Auto pumps with float switches reduce monitoring time, but manual pumps give direct control when needed.
- Head height (lift) requirements: Check the maximum head to ensure the pump can evacuate water from your bilge or reservoir.
- Outlet size compatibility: Most boats use 1-1/8″ or 3/4″ hoses; confirm your hose diameter matches the pump outlet.
- Build and materials: Marine-grade construction and anti-airlock features improve longevity in saltwater and rough conditions.
- Power and wiring: 12V systems are common; consider current draw and available fuse protection on your vessel’s circuit.
- Accessories: Some kits include hoses and thru-hull fittings; others require separate purchases. Plan for fittings compatible with your setup.
FAQ
- What is the typical bilge pump flow rate I need for a small boat? A: For small boats, 750–1100 GPH often provides sufficient drainage for normal bilges and occasional spillover, depending on bilge size and water input.
- Should I choose an automatic bilge pump? A: Yes if you want hands-free operation; auto pumps turn on when water rises and shut off when dry, reducing manual monitoring.
- What outlet size should I look for? A: Common outlets are 3/4″ and 1-1/8″; match the hose diameter in your installation for a secure fit.
- Do these pumps work in freshwater and saltwater? A: Most are designed for both. Verify marine-grade construction and anti-airlock features for reliability in harsh environments.
- Is a float switch necessary? A: It’s convenient for automatic operation, but some setups use a separate float or manual control depending on installation.
- What about warranties? A: In this selection, some models offer extended warranties (e.g., SEAFLO with 4-year coverage); check the product page for details.
