Danfoss 180B0029 PAHT 6.3 High Pressure Water Pump
Keeping technical water systems running smoothly comes down to choosing a pump built for the job, and the Danfoss 180B0029 PAHT 6.3 does exactly that. This axial piston pump is engineered specifically for demanding technical water applications like deionized, demineralized, and reverse osmosis water, delivering consistent flow up to 4.7 GPM and pressures reaching 1450 psi. Its all-stainless steel construction stands up to the corrosive nature of ultra-pure water while keeping the pump lightweight and compact enough to fit into tight system layouts.
What sets this pump apart is how little it asks of the people running it. Because the PAHT 6.3 is water-lubricated rather than oil-lubricated, there's no separate lubrication system to maintain, no belts, and no gearbox to service. That translates into a pump that keeps performing reliably over a long service life with minimal downtime for upkeep. It also runs with remarkably low pressure pulsation, so many installations can skip the pulsation dampener altogether, simplifying the overall system design.
Beyond its use in water treatment and desalination, this pump shows up in a surprising range of industrial settings, from high-pressure cleaning in electronics manufacturing to dust suppression, humidification, and diesel engine emissions control. Whether it's paired with an electric motor or a combustion engine, the 180B0029 adapts to boosted inlet pressure setups or straightforward tank-fed supply lines, making it a versatile choice for engineers who need dependable performance across varied technical water applications.

Frequently Asked Questions
Q: Does the Danfoss 180B0029 require an external lubrication system?
No, the PAHT 6.3 is water-lubricated, so it does not need a separate oil or grease lubrication system, which simplifies maintenance and reduces upkeep costs.
Q: Can this pump be powered by something other than an electric motor?
Yes, the 180B0029 can be driven by either an electric motor or a combustion engine, giving flexibility depending on the application setup.
Q: Is a pulsation dampener needed with this pump?
In most cases, no. The PAHT 6.3 produces negligible pressure pulsation, so many systems can operate without a dampener.
Q: What types of water is this pump designed to handle?
It is built for technical water applications, including deionized water, demineralized water, and reverse osmosis water used in high-purity industrial processes.
Q: Can the pump run with a boosted inlet pressure or draw from a tank?
Yes, the 180B0029 is suitable for both boosted inlet pressure configurations and simple tank-fed water supply setups.
