Danfoss 180B0020 PAHT 25 High-Pressure Water Pump
The Danfoss 180B0020 PAHT 25 is a compact, oil-free axial piston pump built for applications where water purity and mechanical reliability matter equally. Instead of relying on separate lubrication oil, this pump uses the water itself to lubricate its moving parts, which removes the risk of oil contamination entirely. That design choice makes it a natural fit for facilities producing electronic components, running humidification systems, or managing adiabatic cooling loops where even trace contamination can cause costly problems.
What stands out about the PAHT 25 is how much performance is packed into such a small footprint. It can push water up to 160 barg while moving over 52 liters per minute, yet it remains one of the lightest and most space-efficient pumps in its category. Because it can be mounted either horizontally or vertically, plant engineers have real flexibility when integrating it into existing piping layouts without redesigning the surrounding system.
Reliability is also part of the story. The stainless steel construction resists corrosion from continuous water exposure, and the pump's efficient internal design means it doesn't need a separate cooling circuit, even under sustained high-pressure operation. With service intervals that can stretch up to 8,000 hours, the 180B0020 is built to keep running with minimal downtime, making it a dependable choice for continuous industrial water processes.
