How a Launder Transfer Pump Works

The outlet of the Launder Transfer Pump is mated up to a small opening in the divider wall. The metal level is even on both sides of the divider wall when the pump is not operating.

The metal level in the furnace may change, but the pump maintains the metal at a constant level in the launder. A laser metal level sensor can  be used to monitors the level in the launder and adjusts the pump speed.

When the pump stops, the metal in the launder either drains out of the launder or flows back into the pump well. The metal level returns to the level in the furnace.

When the pump turns on, the metal level is pushed through the opening in the divider wall, lifting the metal level on the other side of the wall. The metal level rises and begins to flow down the launder.
