Peristaltic pumps, like the one pictured above, provide a safe and efficient way to pump many liquid chemicals into a pool’s circulation system. Their closed design prevents gases from escaping into the air, and their electronically timed rotation keeps chemical dosage consistent.
Manufacturers of chemical feed systems offer a variety of feeder components, sized for a variety of applications. The image above offers a size comparison between several different types of liquid chemical pumps.
Some chemical feeders, like the one pictured to the right, include detection systems for water chemistry parameters like pH and ORP. This enables the feeder system to dispense chemical doses in direct accordance with up-to-the-minute data on the demands of the water.
