S Series Smart Peristaltic Metering Pumps

Stenner S Series Smart Peristaltic Metering Pumps

The Stenner S Series is an advanced, programmable peristaltic metering pump platform designed for demanding water treatment, industrial process, manufacturing, and commercial chemical injection applications. Built with smart controls, multiple operating modes, integrated diagnostics, and process control compatibility, the S Series provides precise chemical dosing while delivering the monitoring and automation capabilities modern systems require.

Available in the S30, S40, and S50 models, the S Series offers outputs up to 315 GPD at 25 PSI and 125 GPD at 100 PSI, along with a 100:1 turndown ratio for exceptional dosing flexibility.

Smart Control and System Integration

The S Series interfaces directly with process control systems and supports:

• 4-20 mA input and output

• 0-10 VDC input

• Modbus RTU over RS-485 capability

• Hall Effect water meter inputs

• Pulse inputs

• Three programmable output relays

• Backup pump operation

An OLED display and digital keypad simplify setup, monitoring, and calibration while password protection helps prevent unauthorized changes to programming.

Nine Operating Modes

The S Series can be configured to match a wide variety of applications:

• 4-20mA scalable/invertible

• 0-10VDC scalable/invertible

• Manual

• Timer (7-day/24-event)

• Cycle Timer

• Pulse

• Hall Effect

• PPM Feed Flow Switch

• PPM Feed Hall Effect

Advanced Monitoring and Diagnostics

A key advantage of the S Series is its built-in pump status monitoring. The OLED display and programmable relays can provide alerts for numerous pump conditions, including:

• Tube Leak Detection

• Tube Change Alerts

• High Signal

• Low Signal

• High Flow

• Low Flow

• Drive Fault

• Standby

• Mode Change

• Signal Overrun

• Backup Pump Transfer

The integrated leak detection system can trigger alarms, stop pump operation, or automatically switch operation to a backup pump.
