Engineered Solutions Peristaltic Pump Dispenser Peristaltic pump dispensers transfer low viscosity liquids by pressure displacement applied to a turning rotor against a tube carrying material. Usually these pumps are chosen because the liquids are hazardous or difficult to work with and it is advisable to limit operator contact. Another reason is that peristaltic pumps are air free. The model PPD-130 offers excellent features for air-free positive displacement dispensing of materials such as cyanoacrylate, solvent, alkaline and acid. Dispense outputs can be timed from 0.01 - 99.99 seconds with flow speeds from 0.01 - 6ml/min using Teflon tubing and from 0.1 - 20ml/min using silicone tubing. The pump is bidirectional allowing snuff-back after discharge to prevent dripping of the fluid. Air free dispensing Forward and reverse motion Instant reverse for snuff-back cuts off liquid flow Adjustable interval before reverse direction Teflon and silicone tube options Continuous or timer modes Large segment digital LED display Output signal to indicate end of dispense cycle Clean room compatible Simple load mechanism also provides easy cleaning Suitable for small shots and continuous operation Adjustable rotor speed in volume 0 - 10 Self priming from bottle or jar Teflon tubing for smaller discharges at lower flow rates Silicone tubing for larger discharges at higher flow rates System operated by finger switch on holder or remotely from I/O connector at rear of unit • Timer display counts down for discharge
