MARK-3® Portable High-Pressure Fire Pump

Launched in 1964, the MARK-3® lightweight portable pump has been the pump of choice for most wildland fire agencies around the world for decades. Backed by its proven record, the MARK-3® pump today is known for high performance, reliability and durability. Its consistent high-pressure output, ability to pump in tandem or series, and toughness to withstand the rigours of firefighting have made the MARK-3® the core of most remote water-delivery systems in wildland fire suppression. Following a series of improvements in 2015, today the MARK-3® gives new meaning to durability and reliability.
