Frac pump plungers

A pump’s plunger is constructed of a strong, yet malleable metal designed not to crack under pressure, then hard-coated to resist wear. However, as the plunger strokes in-and-out of the packing over millions of cycles, it eventually begins to wear.

Our plunger remanufacturing program offers a significant cost savings by taking worn plungers and bringing them back to like-new condition. We will bring a collection bin to your location for storing used plungers, and set-up a schedule to pick them up and leave a new bin. After receipt, used plungers are machined back to the bare metal specifications, recoated and refinished to ensure the same quality finish as our new plungers.

Dawopu manufactures high-quality OEM parts and consumables,

including industry-leading plungers, available to fit any manufacturer’s pump.

Our plungers, like all our consumables, meet the same rigorous quality

standards as our pumps and fluid ends. We manage the entire manufacturing

process in-house, from material sourcing and rough machining to spray and

fuse, and the final coating. Our facility is 100% dedicated to excellence in

plunger manufacturing, ensuring superior performance and reliability.
