Product Description
The 3ZB-1800 (1340) type triplex plunger pump is a positive-displacement, reciprocating, horizontal, single-acting pump that is primarily used for intermittent well servicing operations such as fracturing, acidification, water injection, and sand prevention. It is mainly composed of a fluid end, a power end, and a lubricating system, characterized by high output power, high pressure, and large displacement.
The power end housing employs a rigid welded structure, while the fluid end offers a selection of plunger diameters, including 4" (φ101.6 mm), 4-1/2" (φ114.3 mm), and 5" (φ127 mm), to satisfy the user requirements for various pressures and displacements.
