Peristaltic pump dispensers transfer low-viscosity liquids by pressure displacement applied to a turning rotor against a tube-carrying fluid.
The peristaltic movement extends the life of the tube and generates fewer air bubbles in the fluid. Various materials such as instant adhesives (cyanoacrylates), thread-locking fluids, anaerobic adhesives, solvents and medical fluids can be consistently dispensed using either a PTFE or a Silicone tube.
The pump is bidirectional allowing snuff-back after discharge to prevent dripping.
