The S Series is a smart peristaltic metering pump designed to interface with process control systems utilizing a 4-20mA output signal and three output relays. The rugged construction includes a totally enclosed housing built to NEMA 4x. Select from 9 modes of operation: 4-20mA scalable, invertible; 10VDC, scalable, invertible; 7-day/24hr Timer; Pulse; Hall Effect; Cycle Timer; PPM Feed flow switch; PPM Feed hall effect and manual. Select from several indicators to communicate the pump status. Password protection prevents unauthorized access to the programmed settings. Program the transfer function to activate a relay to start a second S Series as a backup to the primary pump. The pump can be programmed to respond based on a selected pump condition such as tube leak, tube change, standby, repeat pulse, run, mode change, low or high signal, low or high flow, drive fault, signal overrun, transfer and off via output relay or MODBUS. Agency listings include NEMA 4X, NSF 61 & 372, cULus indoor/outdoor; CE IP65 and NSF 50 are also available on certain models. The brushless DC motor is equipped with ball bearing support and the switch power mode offers energy efficiency. The splined shaft designed pump head and roller assembly allow smooth installation and replacement. Simple tube replacement.
