Cementing pumps are core high-pressure operating equipment in petroleum drilling and completion operations. They mainly adopt a three-cylinder or five-cylinder plunger pump structure, and can continuously and stably deliver media such as cement slurry and spacer fluid under high-pressure and large-displacement working conditions.

Driven by the power system, the plungers perform reciprocating motion to inject the prepared cement slurry into the wellbore annulus at a set pressure, completing cementing and sealing. This ensures tight bonding between the casing and the formation, realizes wellbore sealing, strengthens the well wall, and prevents fluid channeling between formations.

Widely used in cementing, fracturing, pressure testing and other engineering operations in onshore and offshore oil and gas fields, they feature high pressure, large displacement, reliable operation, wear resistance and corrosion resistance.
