Danfoss 180B0024 PAH 2 High-Pressure Axial Piston Pump
The Danfoss 180B0024 PAH 2 is a compact, high-pressure axial piston pump built to move water efficiently without relying on oil for lubrication. Instead, the pump uses the water it's pumping to lubricate its own moving parts, which keeps the design simple, reduces maintenance needs, and helps it hold up well over long periods of continuous use. Its all-stainless-steel body resists corrosion, making it a solid choice for demanding water applications where reliability really matters.
What stands out about this pump is how much capability is packed into such a small footprint. It's a fixed displacement design, meaning output flow scales directly with input shaft speed, giving predictable performance whether it's driven by an electric motor or a combustion engine. It can pull from a boosted inlet supply or draw directly from a tank, which gives installers flexibility depending on the setup. Because pressure pulsation is naturally low, there's no need for an additional pulsation dampener, simplifying the overall system.
This pump shows up in a wide range of settings beyond just marine or industrial use, including humidification systems, flushing and cleaning processes, fire suppression setups, and general high-pressure water delivery for both stationary and mobile equipment. For anyone needing a dependable, low-maintenance pump that can handle sustained high-pressure output, the PAH 2 offers a strong balance of durability, efficiency, and straightforward operation.

Frequently Asked Questions
Q: Does the Danfoss 180B0024 PAH 2 pump require oil for lubrication?
A: No, the pump uses the water being pumped to lubricate its internal moving parts, so no separate oil lubrication system is needed.
Q: What drive options work with the PAH 2 pump?
A: The PAH 2 can be powered by either an electric motor or a combustion engine, depending on the application setup.
Q: Can this pump draw water directly from a tank?
A: Yes, it's suitable for both boosted inlet pressure supply and direct water draw from a tank.
Q: What material is the pump body made from?
A: The pump body is constructed from AISI 304 stainless steel for long-term corrosion resistance and durability.
Q: Is a pulsation dampener needed with the PAH 2 pump?
A: No, the PAH 2 has extremely low-pressure pulsation, so a pulsation dampener is not required.
