Danfoss 180B0007 PAH 12.5 High Pressure Axial Piston Pump
The Danfoss 180B0007 PAH 12.5 is a compact, water-lubricated axial piston pump built to move water at high pressure without relying on oil for internal lubrication. Because the pumped fluid itself lubricates the moving parts, this design eliminates the need for external lubrication systems, simplifies maintenance, and keeps the pump lightweight compared to traditional high-pressure hydraulic units. Its fixed displacement design means flow output scales directly with shaft speed, giving engineers predictable, repeatable performance across a wide range of installation setups, whether mounted horizontally or vertically.
This pump is well suited for demanding water-based applications that call for consistent high-pressure output, including industrial water treatment, dust suppression systems, DI and ultra-pure water processing, and general water hydraulic power transmission. Its AISI 304 stainless steel body resists corrosion in continuous water contact environments, and its compact footprint makes it a practical choice for facilities where space and weight are limited. Long service intervals, up to 8,000 hours, reduce downtime and lower the total cost of ownership for operators running continuous-duty water systems.
Built by Danfoss with a reputation for precision engineering, the PAH 12.5 model brings together compact size, low pulsation, and low airborne noise, making it a dependable option anywhere reliable high-pressure water flow is required, from manufacturing plants to municipal water infrastructure.
