Description:

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.

Working Principle:

The plunger's valves are closed when the upstroke, At the same time, The tube's valve is opened and oil going up to the tube's space. When the downstroke, plunger's valve are opened, the oil going up fromthe bottom of the plunger and inpour vitta .

Machinery Peculiarity:

This pump is include of pump tubing, plunger, coupling-extension, standing valve, the plastics hermetic device (the upper one) and the machinery hermetic device(the nether one). We can get one from two devices above.
