Make purchasing consumable pumps a thing of the past by switching to reusable bottle pumps. Server's stainless steel, hybrid bottle pumps are reusable, durable and easy to clean. Unlike plastic pumps that need to be replaced often and have a negative impact on the environment, our pumps last for years, take up less storage space, improve efficiency and also save on costs. The BP-1/4 pump is constructed of stainless steel with a plastic cylinder and dispenses 1/4 ounce (7 mL) portions directly from a 28 mm bottle 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.
