Practical Functions

The S Variable Series are peristaltic pumps with practical functions such as backup pump capability, leak detection, and remote operation for industrial, water, wastewater, and commercial swimming pool applications. The 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 Series has LED pump status indicators and three output relays for indication from the pump to a separate device, like a process control device.

Leak Detection

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.

Remote Stop or Start

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.

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
detected, or if there is a loss of power or if a drive fault occurs.

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.

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
