3ZB-250 (185) Triplex Plunger Pump
The 3ZB-250 (185) triplex plunger pump, commonly known as the Zhongyuan 80 m3/h pump, is a horizontal, specifically designed triplex plunger pump widely utilized in well-flushing trucks, well flushing-wax removal trucks, and circulating operation equipment. It primarily consists of the hydraulic end, power end, and lubrication system. The power end housing employs a rigid welded structure, while the fluid end offers a selection of plunger diameters, including φ90 mm, φ100 mm, and φ115 mm, to satisfy the user requirements for various pressures and displacements.

Product Description
The 3ZB-250 (185) triplex plunger pump, commonly known as the Zhongyuan 80 m3/h pump, is a horizontal, specifically designed triplex plunger pump widely utilized in well-flushing trucks, well flushing-wax removal trucks, and circulating operation equipment. It primarily consists of the hydraulic end, power end, and lubrication system. The power end housing employs a rigid welded structure, while the fluid end offers a selection of plunger diameters, including φ90 mm, φ100 mm, and φ115 mm, to satisfy the user requirements for various pressures and displacements.
The lubrication at the power end uses an oil pump for mandatory lubrication, with the oil recycled and reused. Similarly, the lubrication at the hydraulic end uses an oil pump for mandatory lubrication, with the oil circulated and reused, and pneumatic forced lubrication is also an option.
