Single vs. Double Action Pump – How to Inflate a SUP Properly

Single-action vs. double-action pump – which difference really matters?
If you've ever inflated an inflatable stand-up paddleboard , you know: the right pump makes the difference between a relaxed start and a sweaty workout on the shore. Especially for beginners, getting the board to the recommended 12–15 PSI can be a bit of a hurdle. But don't worry—with the right pump, it's much easier. But what exactly are the terms single-action pump and double-action pump ? We'll explain that in this article.
How does a single-action pump work?
The single-action pump is the simplest and most robust option. It only pumps air into your SUP when the piston is pushed down . There's no airflow when you pull it up. The principle is easy to understand and even suitable for children.
Advantages:
- Less effort required per stroke – convenient if you like it comfortable.
- Robust, simple and durable – hardly susceptible to defects.
- Ideal for beginners and kids boards , for example from the All-Around Advanced series .
Disadvantages:
- It takes significantly longer for your board to reach the correct pressure.
- With larger SUPs, pumping can be very strenuous.
How does a double-action pump work?
The double-action pump is a favorite among many paddlers. It pumps air into your board both when you push down and when you pull up . Many models can be switched between dual modes: first, for quick inflation, then single mode for the final PSI where more pressure is needed.
Advantages:
- Faster inflation by supplying air in both directions.
- Switchable to single mode – perfect for high pressure applications.
- Particularly practical for large touring or race boards, such as the ZRAY Racing SUPs .
Disadvantages:
- Slightly higher resistance when pumping in dual mode.
- Slightly heavier and more expensive than single-action models.
Comparison: Single-Action vs. Double-Action Pump
feature | Single-action pump | Double-action pump |
---|---|---|
How it works | Pumps only when pressed down | Pumps when pushing down and pulling up |
Pumping capacity | Slower, less volume | Faster, double the flow rate |
Effort | Lighter per stroke | Higher resistance in dual mode |
Area of application | Smaller boards, children & beginners | Large boards, touring, race, frequent users |
Price | Cheaper | Slightly more expensive |
My personal tip
I still remember my first season: With a single-action pump, it easily took me 10 minutes to get my board ready—after that, I was practically exhausted. Today, I only use the double-action pump: First, I quickly add air, then use the single-action pump to add the final PSI. This saves me time and energy for what really matters— paddling on the water .
If you're looking to buy your first SUP board , I recommend a complete set with a double-action pump, such as the ZRAY Allround SUP complete sets . This will ensure you're perfectly equipped.
Conclusion
- Single-action pumps : cheap, simple and perfect for small boards or beginners.
- Double-action pumps : faster, more efficient and ideal for those who paddle regularly or use larger boards.
