Hotsy introduces high-pressure pumps now feature NESTechnology -- nested seal technology -- where the pump actually "nests" the seals of the pump's high-pressure packing assembly in place, supporting the side walls. The nesting assembly includes high- and low-pressure U-shaped seals surrounded by thicker brass pressure rings. For more information call (800) 525-1976 or visit www.hotsy.com/hotsy-pump.aspx.
