Triplex plunger pump
The triplex plunger pump (well-flushing pump) is primarily used for oilfield well flushing, workovers, and other operations. It features a single-acting triplex cylinder plunger design and comprises a power end, hydraulic end, and lubrication system. The power end's reduction mechanism utilizes an external gearbox configuration. The hydraulic end employs packing seals, allowing plunger leakage to be prevented by tightening the packings. After modification, the hydraulic end can handle corrosive media. The power end includes a built-in lubricating oil pump, while the hydraulic end uses pneumatic lubrication. Application Areas: Well-flushing trucks, paraffin removal trucks, combined well-flushing and paraffin removal trucks, boiler trucks Fulsh units, mud pump units Fracturing pump units, cementing and fracturing trucks
