This new Edwards nXDS15iC 8.8 CFM Chemical-Resistant Dry Scroll Pump range from Edwards has exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features. The Edwards nXDS15iC is the best performing pump in its class. The nXDS15iC is up to 20 times quieter than other pumps. Its intelligent control functions and up to five year service interval offer low cost of ownership, making it the small dry pump of choice for today’s most advanced technologies.
It is suitable for use on vapor handling processes, and may be used for some pumping applications involving corrosive substances. The nXDS-C variants have Chemraz® internal valves and stainless steel fittings for extra protection from the pumped media.
Now with an integral pump controller managing the supply of current to a three-phase electric motor in accordance with operating conditions. The controller monitors power and temperature, and will protect the pump in the event of operation under sustained high load or under fault conditions. The controller provides the user interface. The pump may be operated in Manual mode, using the buttons on the interface panel, with a unique feature to control the speed of the pump in Standby Mode to 70% of full speed or with other buttons to increase or decrease pump speed to save wear and tear on tip seals and bearing service life; or a Remote Mode, via serial communications; or a digital and analogue process control (parallel) mode, via the 15-way D-type logic interface connector.
To pump high vapor loads, gas ballast can be delivered into the pump to prevent condensation of the vapor carried by the pumped gases. The logic interface has been designed to support both serial control, parallel control and monitoring, operating through one connector. For serial control either RS232 or RS485 can be selected.
