Frequently Asked Questions

What is a peristaltic (Stenner) pump?

A peristaltic pump moves fluid by squeezing a flexible tube — the chemical only contacts the tubing, never the pump body. This makes the pump highly resistant to chemical corrosion, easy to maintain (tube replacement is the primary service item), and self-priming. Stenner is the leading manufacturer of peristaltic chemical feed pumps for pool applications.

Which Hayward water chemistry controllers is this compatible with?

The Stenner Variable Output pump is part of the Hayward Commercial chemical feed equipment line and is designed to work with Hayward water chemistry controllers including the HCC 2000, CAT 2000, and CAT 4000 series. Confirm compatibility with your specific controller and installation with your pool professional.

What does "variable output" mean?

Variable output means the pump's flow rate is adjustable — you can dial up or down the volume of chemical dispensed per unit of time. This allows the pump to be calibrated to match the specific chemical demand of your pool rather than having a fixed single dose rate.
