Features and Operation

Separate stroke rate and stroke length adjustments provide control over dosing output. The Series A Plus uses an electronic timing circuit and a thermally protected solenoid with automatic reset. Its water-resistant housing supports indoor and outdoor applications, while guided ball check valves help limit backflow and support priming.

The bleed valve helps release air during priming. The series is rated for continuous-duty service, with few moving parts to simplify maintenance.

Applications and Selection

Use this model for chemical feed duties that fall within its capacity and pressure ratings and are compatible with its wetted materials. Confirm the chemical, concentration, operating conditions, and required dosing rate when selecting a pump. Contact Water Treatment Resource for 230-volt options or PVDF liquid ends for acid applications.
