When you need to send water from a storage tank to a point where it is required, you must have an efficient demand or delivery pump. A typical demand pump delivers water from a non-pressurized tank to a point such as a hydroponics garden. It can also be used to boost the pressure from an under-sink RO unit to an ice maker or refrigerator.
As the name suggests, a demand pump is used when there is a demand or need for the water. The pump has an auto-switch that turns it off when water is not needed and on when the need arises. Installing this pump is relatively easy, and its use is a trouble-free experience. It also comes with ½” connect fittings and an 115v cord that can be used to customize any indoor hydroponic garden. At open flow, this pump can deliver an optimal performance of 3.2 gallons per minute.
