S Series

Smart peristaltic metering pump interfaces with process control systems


  • Leak detection
  • Backup pump capability
  • Three output relays
  • Tube change timer
  • Enclosed housing, NEMA 4X
  • Simple tube replacement
  • 2 year warranty

Designed for Demanding Applications

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 and several performance 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. SEE PROGRAMMING VIDEO. The pump is Modbus capable with the accessory kit MOD100.

The identifying item number begins with S30, S40, or S50.

The OLED operating display is easy to navigate with intuitive programming. Select from the various modes of operation:
– 4-20mA – scalable, invertible  SEE PROGRAMMING VIDEO
– 0-10VDC – scalable, invertible
– Pulse
– Hall Effect
– PPM Feed Constant Flow – Flow Switch
– PPM Feed Variable Flow – Hall Effect
– Manual
– 7 Day/24 Hour Timer
– Cycle Timer

The pump can be programmed to respond based on a selected pump condition such as tube leak SEE PROGRAMMING VIDEO, tube change, standby, repeat pulse, run, mode change, low or high signal, low or high flow, drive fault, signal overrun, transfer and off.

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.

NOTICE: The information within the charts above is solely intended for use as a guide. The output data is an approximation based on pumping water under a controlled testing environment. Many variables can affect the output of the pump. Stenner Pump Company recommends that all metering pumps undergo field calibration by means of analytical testing to confirm their outputs
