• Debris filter included to protect the diaphragm and valves
• Clear manual for wiring and plumbing steps
• Mounting holes for secure attachment in tight compartments

What protection and durability features are built in?

The unit is engineered for long life in mobile environments with corrosion-resistant materials and a self-priming diaphragm design that tolerates brief dry running. An integrated pressure switch protects the motor by stopping the pump automatically when taps are closed, reducing wear and conserving power.

• Self-priming capability simplifies startup after empty tanks
• Pressure switch provides automatic on/off control
• Dry-run safe design for short-term operation without water
• Corrosion-resistant components for marine and outdoor use
