The Artesian2 pumps are molded of tough, corrosion-resistant glass-reinforced polypropylene, extremely strong and built for long term service. Their good self-priming characteristics allow them to be positioned above the supply source. The carefully designed internal water passages provide for high flow rates with minimal water noise. An easy-open Lexan™ lid provides easy viewing and access to the oversized strainer basket, which makes installation and service quick and easy. All Artesian2 pumps combine high efficiency and reliability in an external, self-priming pump that will last for years and provide great electricity savings. Artesian2 High Flow pumps are designed for maximum flow rates while still maintaining energy-efficiency and durability. Low RPM and High Head models are also available.
