Product details

The Stenner 45MJH2A1STAA is a single head adjustable chemical injection pump rated for 100 PSI and up to 10 gallons per day, running on 120V.

What it does

The pump meters a treatment chemical into a pressurized line at a rate you set. On commercial pools that usually means sanitizer, or an acid or base feed to hold pH in range. Outside the pool room the same pump handles problem water: dosing for pH correction, or oxidizing iron, hydrogen sulfide and manganese so they drop out and the filter can take them.

Sizing it

Match the 10 GPD ceiling and the 100 PSI rating to your system before ordering. The output is adjustable downward, so a pump with headroom is easier to live with than one running flat out.
