What Is Pumper Apparatus?
Housing a massive centrifugal pump (typically 1,500 GPM), a water tank (500-1,000 gallons), and thousands of feet of hose, this is the foundational fire engine.
⚠️ Operational Safety Warning:Exceeding the pump's cavitation threshold can destroy the impellers and abruptly halt water flow.
