Liquid Chemical Dispensing Systems Adding pool chemicals automatically or on a regular basis minimizes the high and low swings associated with intermittent manual chemical maintenance. The SR-4000 (single pump system) is ideal for applications requiring daily chemical maintenance. With the ability to stack three pumps per drive, these systems can dose from one drop per minute to 70 gallons per day, with many increments in between. The SR-4000 can operate as stand-alone units for periodic injection or maintenance, or in conjunction with Automatic Backwash Controllers.
