Product details

The Stenner 45MJL5A1STAA is a Classic 45 series single head adjustable chemical injection pump. It is the workhorse feeder for liquid chlorine or acid on a pool system, sized for 2.5 to 50 gallons per day against up to 25 psi.

Specifications

The single pump head is adjustable, so output can be set anywhere across the 2.5 to 50 gpd range. It handles 0 to 25 psi of line pressure and uses 1/4 in. tubing on suction and discharge. The head is polycarbonate for chemical resistance, and the motor runs on 120 V 60 Hz.

On the pad

Wire it to a timer or a chemical controller output and it meters a steady, repeatable dose. Because the pump head is adjustable, the feed rate can be trimmed as the pool season changes without swapping tubes or heads.
