Foot Pump - PILOT

A foot pump is a manually operated device that uses foot action—typically stepping or pressing with the foot—to move air or liquids. It functions as a positive-displacement pump, harnessing the strength of the legs which provides greater force and efficiency compared to hand-powered alternatives

Basic Construction and Mechanism
Intake and Outlet Ports: Includes one-way valves to control flow direction—allowing fluid or air in through the intake and out through the outlet 
About Mechanics

Airtight Chamber: A sealed housing or bladder prevents backflow, ensuring efficient displacement during each press cycle 

About Mechanics
Reciprocating Action: Pressing down moves the piston to force fluid out; upon release, it draws intake fluid back in. Springs or internal pistons typically return the mechanism to its initial position
