Abstract
A sprayer system having a trailer, which is pulled by a tractor or other tow body, and has a tank carrying liquid to be sprayed and a spray head. The trailer has a peristaltic pump mounted on a frame and driving pumping power from the wheels of the trailer so that the sprayer is self pumping when the trailer is pulled. The peristaltic pump provides a smooth flow by providing a multiplicity of pulses of liquid produced by the pump from the rotation of the trailer wheels by wrapping the compressible tube of each pump around an assembly of rollers which are rotated by drive wheels. The tube is wrapped at least 360° around the rollers and is held stationary by being connected to fixed outlet and inlets of each pump. The tube lies side by side on at least one of the rollers of each assembly and overlaps that roller.
