Jabsco HotShot HD4 Heavy Duty Washdown Pump - 24V - 4 GPM - 60 PSI

The Jabsco HotShot HD4 Heavy Duty Washdown Pump—24V, 4 GPM, 60 PSI—represents a purpose-built solution for vehicle decontamination, equipment rinse-down, and tactical field sanitation in demanding operational environments. Originally engineered for marine washdown systems, this diaphragm pump has proven itself in law enforcement and military applications where reliable on-demand water delivery is essential. Whether mounted on patrol vehicles, decon stations, or rapid-response units, the HD4 delivers consistent performance without the complexity or failure modes of centrifugal alternatives.

Built around Jabsco's proven diaphragm pump architecture, the HD4 operates via 24-volt DC power—standard across most tactical and emergency vehicle electrical systems—and achieves a practical 4 gallons-per-minute output at 60 PSI operating pressure. This combination delivers adequate flow for effective washing while maintaining pressure sufficient to remove stubborn contaminants without requiring excessive water volume. The robust internal geometry and elastomer sealing surfaces handle both fresh and brackish rinse water, and the pump tolerates brief dry-run periods common in field operations. Weighing 8.85 pounds and dimensioned at 9 x 6 x 18 inches, the unit integrates into compact mounting footprints on equipment racks or vehicle frames without sacrificing durability or serviceability.

Tactical units, hazmat response teams, and law enforcement agencies rely on the HotShot HD4 for rapid biological or chemical decontamination protocols, vehicle exterior washdown, and equipment maintenance in austere conditions. Installation requires basic 24V DC wiring, inlet/outlet port connections (compatible with standard hose barbs or quick-disconnect fittings), and a water source—making field deployment straightforward. The HD4's proven track record across marine, commercial, and industrial sectors translates directly to reliable performance in high-stress operational scenarios where equipment failure is not an option.
