Heidolph Hei-FLOW Expert 600 Peristaltic Pump This model has a flow rate of 2.0 — 4,056 ml/min and i (more)s designed for operation with single-channel pump heads. The analog interface makes it possible that all functions can be controlled externally. A control accuracy of ±3.5% and a conveyor speed of 24 to 600 rpm provide optimum process conditions. In addition, sensitive media can be protected from influence by using the optional foot switch. Like all Heidolph peristaltic pumps, the conveying direction of this model can be changed by a simple push of a button. Furthermore, the accelerated filling and emptying of the tubing is simplified, since here only the button for the maximum speed has to be pressed.

Edwards nXDS20iR Dry Scroll PumpFeatures - Bearing shield ensures separation between process gases a (more)nd bearing lubrication to ensure clean vacuum and no possibility of contamination. - Smart motor drive means consistent performance globally, pump overload protection and remote start/stop capability. - High flow gas ballast feature allows pumping of vapours including water vapour at up to 240 gh-1 - Simple single sided scroll design allows maintenance to be done in minutes for low cost of ownership and maximum up-time. - Enhanced versions offer up to 20% lower peak power requirements during initial pump down. The nXDS allows a wide range of control and communication options The nXDS comes as standard with a manual, easy to use, gas ballast port A perfect companion for your turbomolecular pump With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features Edwards nXDS is the best performing pump in its class.nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise - up to 20 times quieter than other pumps. Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimised pumping performance globally. Unlike the standard nXDS20i, the Edwards nXDS20iR isdesigned for specialist applications such as gas recirculation, rare gaspumping and recovery or other applications where the dilution of the pumped gasis undesirable, or where sealing is integral to minimizing potential gas loss.
