Seven-day timer pump, 22 GPD, 230 VAC

Reliable metering performance—guided dual check valves provide precise seating and excellent priming and suction lift

PVC and PTFE construction with external control

Ideal for water treatment and chemical feed applications

Manual control pumps feature adjustable stroke rate and length, reliable timing circuits, and circuit protection from voltage and current upsets. Leak-free bleed valves provide safe and easy priming. Pumps are water resistant and can be installed outdoors.

What's Included:

Injection/back pressure valve assembly, foot valve/strainer assembly, three-function valve, 4-ft clear PVC tubing, and 8-ft rigid polyethylene discharge tubing. All 115 VAC pumps include a 6-ft power cord with US plug; 230 VAC pumps include a 6-ft power cord (plug not included).

Service kits (sold separately and listed in each table) include valve cartridges with O-rings, head, diaphragm, secondary O-ring, head screws, and washers.Seven-day timer pumps provide a simple and cost effective metering system for timed applications. Pumps offer eight on/eight off programs per week for maximum adjustability. These pumps feed chemical products on a timed schedule and are commonly used in biocide feed applications. Feed cycle is initiated and controlled by programmable timer.
