How does a force pump drain water from deeper mines?

The force pump was developed to overcome the limitations of the suction pump, which relies on atmospheric pressure and is restricted to lifting water to a maximum height of approximately 34 feet (10 metres).1

In a force pump, the mechanism functions through a piston stroke. When the piston moves downward, it forces water out through a side valve. Unlike the suction pump, the height to which the water can be raised is not limited by atmospheric pressure; instead, it depends entirely on the force applied to the piston. This allows the pump to move water from the depths of a mine through pipes located in the shaft to the surface for disposal. Historically, these systems were essential for underground mining as operations moved deeper and natural drainage via adits became insufficient.123
