Lower Cost and Better Features! Longer life, higher efficiency, smaller and lighter weight, easier to reguild, all plastic construction prevents problems from minerals in water. Easier installation -- now only 6 lbx. Includes handy water-tight quick disconnect plug that makes hook-up easy and water-protected without splicing. Dry-run capability -- you won't have to worry about harming the pump if your well runs too low. This pump makes a solar pumping system comparable in cost and performance to a generator-run system -- but without the noise, fuel costs and maintenance. Easy to install in 3-4 hours and light weight enough to move for seasonal pumping. Hook directly to solar modules for daytime pumping or attach to a battery for on-demand water. Positive displacement triple-diaphragm pump with new internal bypass.
