This picture was taken in the office of ETM, a renowned aquarium equipment manufacturer in PA, of USA. Our latest visit to ETM dated back to May 2012 when the lovely VorTech pumps with different sizes were showcased in the fish tank.
The Vortech pump is comprised of two portions. The dry-side portion is having a motor outside ofthe aquarium, meaning no electrical components ever touch the water for a completely safety. The wet-side portion is built with an impeller to cause a water flow, whose parameters can also be changed to most exactly meet your needs.
Our company is a long-term supplier for ETM Company by producing DC brushless motors to fit the dry-side portion of the VorTech pumps.
During the visit, both sides had a serious discussion about how to reduce the noise that possibly arises from any parts of the pump, in an effort to enable pump users to create the healthiest, safest and smartest aquarium to an extreme extent.
