Danfoss 180B0032 PAHT 10 High-Pressure Water Pump
If you're running a system that depends on clean, technical water — whether that's reverse osmosis, deionized water, or ultra-pure water production — the Danfoss PAHT 10 (part number 180B0032) is built to keep that system running without the usual headaches. This axial piston pump uses the water itself as the lubricant, which means there's no oil, no grease, and no separate lubrication system to maintain. That single design choice removes one of the most common failure points in industrial pumps and gives the PAHT 10 a genuinely maintenance-free service life.
What stands out about this pump is how much performance it packs into a small footprint. It's built from stainless steel, so it holds up well in demanding water treatment environments, and it delivers strong, steady flow without the pressure pulsation that usually forces engineers to add dampeners to a system. Because it's a positive displacement pump, the flow stays consistent and predictable regardless of changes in discharge pressure, which makes it easier to design around and easier to trust once it's installed.
The PAHT 10 is equally at home driving desalination equipment, supporting irrigation and water supply systems, or working inside a larger water treatment plant. It handles high recirculation rates without overheating, runs across a wide speed range, and can be paired with either an electric motor or a combustion engine depending on the application. For teams that need a compact, dependable pump they won't have to think about for years at a time, the Danfoss 180B0032 is a solid, proven choice.

Frequently Asked Questions
Q: Does the Danfoss PAHT 10 require any lubricating oil?
A: No, the pump is water-lubricated and does not use any external lubricant, which is part of what makes it maintenance-free.
Q: What type of water can run through the PAHT 10?
A: It's designed for technical water applications, including deionized, demineralized, and ultra-pure water produced through reverse osmosis.
Q: Can this pump be driven by something other than an electric motor?
A: Yes, it can be powered by either an electric motor or a combustion engine, depending on the setup.
Q: Does the PAHT 10 need a pulsation dampener?
A: No, the pump produces negligible pressure pulsation, so a dampener is not required.
Q: How does flow output behave as pressure changes?
A: Since it's a positive displacement pump, flow stays consistent based on shaft speed and is not affected by changes in discharge pressure.
