A head for a peristaltic pump that may be used for delivering ink to a flexographic printing press includes a housing and a roller assembly. The housing is adapted to receive a flexible tube. The housing has a curved wall and a clamp. The clamp secures the flexible tube within the housing. The clamp has an open position and a closed position. The clamp is in the open position when the flexible tube is able to move through an entrance and exit in the housing. The clamp is in the closed position where a first section of the flexible tube is secured in the entrance and a second section of the flexible tube is secured in the exit. The first and second sections are secured where they are not able to be pulled into the housing but are able to gradually slip out of the housing allowing the head to pump in both directions. The roller assembly is rotatable within the housing. The roller assembly rotates about an axis through the housing. The axis is coaxial to the curved wall in the housing. The roller assembly includes at least two compression rollers and at least one guide roller. The compression rollers are peripherally spaced where each of them come successively into contact with the flexible tube during rotation of the roller assembly. Successive compression rollers compress two portions of the flexible tube against the curved wall to confine a finite volume of fluid in the flexible tube. The guide rollers are peripherally spaced between the compression rollers where each of them comes into contact with the flexible tube during rotation of the roller assembly. The guide rollers guide the flexible tube to stay centered with the compression rollers and initiate decompression of the flexible tube to return to a partial compression dimension. Fluid is moved through the flexible tube by rotation of the roller assembly.

A device for weightlifting and bodybuilding that comprises a housing that has and cap on one end that allows the device to be placed onto a typical barbell bar, such as the bars used in plate-loading barbell sets. Small, incremental weights may be easily added or removed from the hollow internal section of the device by removing a lid. An end of a barbell can be fit through the center of a device to secure the device on each end of a bar, or an alternative configuration provides a clamp that attaches a device to an end of a bar.
