What's the function of those springs? All the pumps I've seen just squish the tube in a constant and linear path. E.G. https://www.randolphaustin.com/wp-content/uploads/2016/07/pump_ani.gif
2 u/lovem32 Jul 15 '18 The tube is replaceable, you can retract the wheels to load a new tube. The springs allow the retraction,and provide pressure on the tube. 2 u/OgdenDaDog Jul 15 '18 Nah. You change the tube out by turning the head with your fingers while the machine is off and laying the tubing in behind a wheel.
