- Leak detection
- Backup pump capability
- Remote start or stop
- LED Indicators
- Three dedicated output relays
- 2 year warranty
20:1 Turndown
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.
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 allow smooth installation and replacement.
The identifying item number prefix begins with S3V, S4V, or S5V.
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 if a drive fault occurs.
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.
Stenner Peristaltic Pump Advantages
