Fixed & Variable Rate | S Fixed & Variable Series

The S Fixed and Variable Series Pumps 

  • Backup pump capability
  • Output Relays: Leak Detect, Run, Transfer 
  • LED Indicators: Run/Fault, Standby, Leak, Power

Flow Rate Outputs
2.0 to 150.0 gpd, pressures to 25 psi maximum
0.3 to 60.0 gpd, pressures to 100 psi maximum

 

The S Variable has an adjustable potentiometer and the S Fixed is a fixed speed pump.

The S Fixed and Variable Series are peristaltic pumps that offer practical functions for industrial, water and wastewater, and commercial swimming pool applications.

The variable pumps have 20:1 turndown and run at the speed set with the adjustable potentiometer when power is applied or the standby input is removed.

The fixed models run at the factory set speed when power is applied or the standby input is removed; they do not have an on/off switch  Both series have LED performance indicators and three output relays for indication from the pump to a separate device, like a process control system.

The pumps have a durable totally enclosed housing with NEMA 4X rating. The brushless DC motor is equipped with ball bearing support and the switch power mode offers energy efficiency. The splined shaft in the pump head and roller assembly allows smooth installation and replacement. Tube replacement does not require tools and is fast and easy with the patented pump S4 QuickPro®  pump head.            
   

KEY FEATURES

    Leak Detect Jumper

    The pump includes a factory installed Leak Detect Jumper to stop the pump if a leak is detected.  The  jumper may be removed to allow the pump to continue to run when a leak is detected.

    Three Dedicated Output Relays

    • Leak Detect: Sends relay to indicate a leak is detected.
    • Run: Sends relay to indicate pump is operating.
    • Transfer: Sends relay from the primary pump to transfer operation to a back-up pump, if a leak is detected, or if there is a loss of power or a drive fault.

    Standby Input

    The Standby Input can receive a dry contact signal to remotely stop or start the pump. The standby input is also utilized with the transfer relay to set the primary pump to transfer operation to a back-up pump.

    Advantages of All Stenner Peristaltic Pumps

    • Self-priming against max. working pressure; foot valve not required
    • Solutions do not contact moving parts
    • Pump head requires no valves, allows for easy maintenance
    • Does not lose prime or vapor lock
    • Pumps off-gassing solutions and can run dry.
    • Output volume is not affected by back pressure.
    • Simple tube replacement without tools

    exclamationNOTICE: The information within this chart 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.
