Technical Performance & Characteristics

1. The pump barrel is made of high-quality special tubes, and the internal surface is hardened through chrome or nickel-phosphorus plating, resulting high strength, rigidness and corrosion-resistant performance.
2. The surface of the plunger is subject to build-up welding with nickel-based alloy powder, thus the corrosion-resistant performance is enhanced.
3. The valve ball and seat are made of high carbon chromium stainless steel, tungsten carbide, titanium carbide or other materials, thus its service life is extended.
4. High pumping efficiency and long inspection cycle.
5. Compact structure and easy installation and maintenance.
