The SmartStream pump is said to eliminate striking of a piston to a seat or nozzle. Each cycle displaces a column of material, rather than a single sphere. Cycles at frequencies that create a stream of material that reportedly can deliver increased flow rates (greater than 70 ÿl/sec). The displacement piston, driven by a linear motor/encoder assembly, is carbide. Design allows for easy removal and cleaning of the fluidic module. Only three o-rings need to be replaced. Z travel of dispense head is said to be virtually eliminated, as material is released from a nozzle 2-3 mm above the PCB surface. Reduces number of height senses needed.
