If you have used the very popular, good quality "AD20P" model pump, you will be equally if not more satisfied with this pump. Here's a picture of the very popular AD20P next to this pump. Both feature brushless motor, ceramic components, and extremely long run lives of 20-50,000 hours. However, this pump features a new rare earth magnet (NdFeB) motor and a circular stator design, resulting in a more compact pump that is extremely quiet and extremely energy efficient. This pump is more efficient than the AD20P with similar performance characteristics. It will run on as little as 6 volts and handle up to 16V. This pump is not rated for submersible operation - connect 5/16" ID x 7/16" ID or 3/8" OD x 1/2" OD tubing to the inlet, and 1/4" x 3/8" tubing to the outlet. We have two variants of this pump: a slightly larger more powerful version (the listing you're reading), which is not meant to be submersed for long periods of time, and a slightly smaller IP68 submersible model designed for continuous operation under water.
