Product Description
This is a conventional tubing pump, but it offers improved performance in terms of corrosion resistance and anti-friction properties. The plunger is nickel-plated on an alloy base, and the inside wall of the barrel is coated with hard cadmium. Key components such as the valve hood and valve ball are made from materials that offer excellent mechanical performance and corrosion resistance. Compared to traditional pumps, this series provides a longer working life.
