Abstract
The article describes the design of a powerful dc conduction pump operating on an increased voltage. The pump has a channel with sectional electrodes and is intended for pumping liquid potassium at 9 temperature of 700^°C. The head-discharge characteristic of the pump in the section (p = 24.5·10⁵ N/m²; Q = 0.015 m³/sec) -(p=14.7·10⁵ N/m²; Q = 0.0296 m³/sec) is linear. In the dc regime the supply is 14,870 A, voltage 15.5 V, discharge 0.0296 m³/sec, head 17.6·10⁵ N/m², and induction in the gap of the magnetic system 0.27 T. The maximum total efficiency of the pump is 25
