Measurement Guide


To get the best possible results from your hydropump, it's important to pick the right size. If you choose an overly large pump, or one that's too small, you may not receive the maximum pressure, resulting in less impressive results.

Follow our correct measurement guide below:

MEASURE-1Measure your erect penis with a ruler pressed lightly onto your pubic bone. You`ll find a ruler is easier than a tape measure.

Record the measurement from the pubic bone right up to the tip of your penis.

MEASURE-2Measure the circumference of your erect penis around the middle of your shaft

You’ll find a tailors tape measure is easiest, but a piece of string wrapped round and then measured against a ruler after will do.

Now Select Pump Range By Your Size

Note: It’s important to make sure you choose the right size pump to maximize the performance gains you get. Choosing a pump that is too big for you can reduce vacuum pressure and consequently cause less effective exercise.
