subsurface sucker rod pump

Comparing with conventional tubing pump, ours has better performance in corrosion resistance & anti-friction aspect. Plunger of it is nickel plated on alloy base, inside wall of barrel is plated with hard cadmium, key parts, such as valve hood, valve ball, are made of materials with excellent mechanical performance and corrosion resistant property. Compared with conventional pump, the series of pump has a longer working life.
