Since there was some interest in this on the Tunze thread:
This pump is what caused the biggest commotion at MACNA. This is the VorTech. The propellar assembly fits inside the tank, and the motor fits on the outside. It uses low voltage, and has a thermal switch inside to prevent damage. It moves over 3000 gph
The black part is the power supply for the pump. The white metal housing holds the controller.
Here it is attached to the side of the tank. The yellow balls near the base were added to show the flow through the tank. These are some that were sucked against the intake grate.
