**How a Diaphragm Pump Works:**
1. The pump is driven by an AC or DC motor.
2. A valve assembly with multiple chambers and diaphragms creates suction as the motor turns, pulling fluid through the inlet.
3. The flow rate depends on factors like the number of chambers, cam offset, pressure, and fluid viscosity.
**Applications:**
- Yacht/RV/Caravan pressurized water systems
- Sprayer fixtures (vehicle-mounted sprayers, electric sprayers)
- Clean machines, humidifiers, water purifiers, medical devices
- Food and beverage filling & liquid transfer
- Any other pressurization system
