Eco bottle pumps from Server Products are NSF listed and cleanable. They offer superior performance and precise portion control and because of their durability, they will not wind up contributing to a landfill like disposable pumps. This hybrid stainless steel and plastic pump has been completely redesigned to dispense smooth condiments (without particulates), directly from a manufacturer's container with a 38 mm opening. The one-piece discharge tube with over molded knob and combination ball/pinch valve design has only a few parts. And clean-in-place certification makes maintenance a breeze.
