Hand pumps are manually operated pumps that use human power and mechanical advantage to move fluids (liquids or gasses) from one place to another. Hand pumps are used widely around the world for industrial, marine, irrigation, and leisure activities. Hand pumps generally operate on a piston, diaphragm, or rotary vane principle with a check valve on the exit and entry ports operating in opposing directions. Most hand pumps use positive displacement to move fluids and are either piston pumps or plunger pumps.

The pump includes the name “Lezyne” in capital letters above the words “Pressure Drive,” also in capital letters near the top of the pump’s body.
