That’s a fluid o tech GA series pump, they come as a Bushed or Brushless DC pump. They use a 24V DC transformer. They are a rotary, not a gear pump. The model shown is the Brushless motor, as they use the square motor casing.
The upgrade cost is ridiculous, and they are cheaper than the gear pump used in the V, which is almost 70% smaller. They are quiet though and come with a steel or brass pump head.
