S Series Pumps offer advanced control
The flagship S Series pumps combine smart technology and simple programming for demanding applications. They feature multiple performance indicators and operational modes, and allow you to fine-tune them to suit your application.
Pumps accept multiple inputs and can be set for 7-day/24-hour timers, cycle timers or PPM feed. You can even link two S Series pumps together, and use a programmed transfer function on the first pump to activate the second pump in alarm conditions. An integrated leak detection system and programmable tube life timer alert you when maintenance is needed.
Chemical Compatibility
Use with aluminum sulfate (alum), ammonium chloride, ammonium hydroxide, ammonium sulfate, 5% calcium hypochlorite, ferric sulfate, 48% fluoride, 37% hydrochloric acid, 50% hydrogen peroxide, magnesium hydroxide, peracetic acid, potassium permanganate, sodium bisulfate, sodium hydroxide (caustic), sodium hypochlorite and 40% sulfuric acid. Call for compatibility with other chemicals. Wetted materials: Santoprene pump tube w/ polypropylene/PVC adapter fittings, polyethylene suction and discharge tubing, polypropylene/PVC suction strainer, polypropylene/PVC injection fitting (25 psi models) or polypropylene/PVC injection check valve (100 psi models).

S Variable and S Fixed pumps offer simpler operation
S Variable and S Fixed pumps provide practical functionality for an economical price. They feature three output relays and LED indicators to show pump status at a glance. S Variable models have an adjustable potentiometer for variable speed control while S Fixed models offer a steady fixed-rate run speed. Both series are suitable as backup pumps to a standard S Series pump, and can be activated by the transfer function under alarm conditions.
