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

Single vs. Double Action Pumpe – SUP richtig aufpumpen

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.

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.
