Submersible brushed DC pump, 3V, ~100mA, vertical outlet port. Must remain submerged at all times; polarity reversal does not reverse flow. Choose this over the horizontal variant when a vertical outlet simplifies plumbing.

One of the pump power wires for the submersible 3V DC water pump. Source describes the pump as a DC motor powered with 3V and says reversing polarity does not make it a suction pump.
Second pump power wire for the submersible DC pump. Use across a switched transistor or motor-driver output as described by the source.
