3ZB-670/900HP positive displacement pumps

3ZB-670/900HP positive displacement pumps are widely used for intermittent oilfield operations like acidizing, fracturing, well killing, and so on. This horizontal reciprocating frac triplex plunger pump is designed in two plunger diameters (4”and 4-1/2”) to fulfill multiple pressures and displacements and they adopt the same power end. In this frac triplex plunger pump, the maximum rated brake power is 670 KW (900 HP), and the stroke is203.2 mm(8”).
