Excellent pumps for high pressure and very low volume applications such as misting, cooling, etc. (High pressure misting with the correct nozzles provides a small droplet size to provide a "dry" mist which cools without undue wetting). Both models feature built-in pressure regulator, extruded aluminum body with Teflon hardcoat, stainless plunger and valves and nitrile o-rings. Model 213 also features new 10,000 hour seal system. Models shown below include 120V motors; 12V motors also available. Simple maintenance can be done with hex wrench and repair kits.
