Bait Pump Buying Guide

For any angler who wants to exploit the effectiveness of live bait, a bait pump is a must-have in your gear. They work with bait tanks to ensure your bait stay alive in captivity and as fresh as possible for when you’ll need to make a catch.

Our buying guide reviews the best bait pumps on the market based on their specified features and tested performance to give you the best options to choose from. We then take it a step further to outline the particular factors you should consider and qualities you should look out for in a bait pump before you make a purchase.

Size of Bait Tank

The first factor you want to consider before you buy a bait pump is the size of the bait tank you want to aerate. Smaller tanks will make a smaller air demand and ultimately require smaller bait pumps. A particular important indicator of the bait pump’s size is its labeled pumping flow rate. It is usually labeled in liters per minute and places a measure on how much air the pump moves per time.


Another important factor you want to consider is the pump’s power rating and options. In general, the larger the pump or flow rate, the more power it will draw. Depending on the brand, smaller bait pumps, in general, are powered by D batteries. For larger bait pumps with higher air demand, they typically use the DC outlet on your cigarette lighter to run.

Low-noise Performance

Another important quality you want to see on any bait pump is low-noise performance. The bait pump should come in a housing that damps sound and should resonate with the tank so it makes noise. The quieter, the better so that it doesn’t agitate your bait.

Waterproof Performance

Any bait pump you are going for should be highly waterproof as it will spend most of its life around water and splashes are very likely. AA well-sealed housing will keep water out of the water-sensitive electrical components to prevent short-circuit damage or corrosion and will ensure long service life.
