Watson-Marlow Bredel's 313 pumphead features secure clamps that allow more clearance during loading and prevent tampering. It has no valves, is self-priming and can run dry without incurring damage. Loading involves three steps: sliding open the track to expose the rotor; placing the tubing over the rotor; and sliding the track down. The unit is available with a choice of three or four rollers and fixed or variable tube clamps.
