**High Quality Electric Water Pumps, Self-Priming Pump for Sea Water**
**11.3LPM / 3.0GPM | 55PSI**
**Description:**
This high-performance electric water pump is designed for use in marine, RV, yacht, and caravan systems. It features a run-dry capability, allowing it to operate without fluid without causing damage. The pump includes quick-connect ports for easy installation, and the hose kit is included. It is self-priming, meaning it can start pumping even when initially dry. It also has ignition and thermal protection for added safety and durability.
**How a Diaphragm Pump Works:**
1. The pump is driven by an AC or DC motor.
2. A valve assembly with multiple chambers controls the flow. Each chamber contains a diaphragm that moves back and forth, creating suction and pushing fluid through the system.
3. The flow rate depends on factors like the number of chambers, cam offset, operating pressure, and fluid viscosity.
**Applications:**
- Yacht/RV/Caravan pressurized water systems
- Sprayer fixtures (vehicle-mounted sprayers, electric sprayers)
- Clean machines, humidifiers, water purifiers, and medical equipment
- Food and beverage filling, liquid transfer
- Any pressurization system
