The pump begins with a large cylinder, allowing you to push a lot of fluid at low pressure, once the pressure begins to climb; the pump automatically shifts to smaller cylinders allowing the operator to add pressure to the shore with little physical effort. This combination reduces the stroke count dramatically as well as reducing the physical effort significantly.
Wheels make it easy to move on job sites.
An Auto Shifting 3 Stage Pump
Dramatically reduces (up to 60%) the number of strokes required to bring a shore to pressure.
