The Hydrolock™ In-Line Water Pump is a true workhorse providing HydroLock Covered Irrigation systems with appropriate flow and pressure specifications. This pump applies constant pressure to the Tornado Mist Sprayer for maximum root zone coverage. This 3-chamber diaphragm provides up to 3.3 gallons per minute and is capable of self-priming up to 6 vertical feet, and can run dry without damage. There is a plug for any standard US wall outlet for ease of use.

Most pumps used for indoor gardening do not hold optimal pressure for irrigation. In addition, most pumps fail rather quickly when running nutrient solutions and other particulates. The 33 Series packs a punch with pressure up to 45 PSI and is completely compatible with all nutrient solutions.
