VSP 50 
    Vehicle Mounted Thom-Katt® Pump
    Now added to our Vehicle-Series product line with the VSP 50 Vehicle
  Mounted Thom-Katt® Pump. It doesn’t require a CDL to operate, which
  means more versatility for your staff. It delivers the same high-level
  performance and output as the reliable Thom-Katt® pump on a rugged
  flatbed-style chassis. The VSP 50 is well suited for pumping grout,
  block fill, and shotcrete applications due to its ø6” (150mm) concrete cylinders.
