Chemical Resistance Guide
The S Fixed and 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 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 with the patented pump S4 QuickPro® pump head.
The identifying item number prefix begins with S3F, S4F, S3V and S4V.
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.
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.
