Danfoss APP 0.8 Axial Piston Pump – Part Number 180B3037
The Danfoss APP 0.8 is a compact, high-pressure axial piston pump engineered to move low-viscosity, corrosive fluids with remarkable efficiency. Built around a fixed displacement design, it delivers flow that stays proportional to input shaft speed no matter how much back pressure the system generates, which makes it a dependable choice for operations that demand consistent output under changing conditions.
What sets this pump apart is its simplicity. There's no oil lubrication to manage, since the fluid being pumped lubricates the internal moving parts on its own. That means fewer maintenance headaches and a longer working life with very little upkeep. The pump body is constructed from duplex and super-duplex stainless steel along with carbon-reinforced PEEK components, giving it strong resistance to corrosion even in harsh, high-salinity environments. An integrated flushing valve also allows fluid to pass from inlet to outlet when the pump isn't running, helping protect internal components between cycles.
Lightweight and easy to install, the 180B3037 fits well into systems where space and weight matter, and it can even be paired with a combustion engine using the appropriate coupling. Whether it's supporting a treatment process, an irrigation setup, or another high-pressure fluid transfer application, this pump is built to run efficiently for the long haul with minimal service interruptions.

Frequently Asked Questions
Q: Does the Danfoss APP 0.8 require oil for lubrication?
A: No, the pump uses the pumped fluid itself to lubricate its internal moving parts, so no separate oil lubrication is needed.
Q: What kind of fluids can the 180B3037 pump handle?
A: It's designed for low-viscosity, corrosive fluids such as seawater, brackish water, and other saline solutions.
Q: Can the pump run on a combustion engine?
A: Yes, as long as a special coupling designed for that purpose is used.
Q: How does the flow rate respond to pressure changes?
A: Since it's a fixed displacement pump, flow stays proportional to shaft speed regardless of counter-pressure.
Q: What happens to the pump when it's turned off?
A: The integrated flushing valve lets fluid pass from inlet to outlet while the pump is idle, helping protect the internal components.
