3ZB-750/1000HP Triple Plunger Reciprocating Pump

3ZB-750 or 1000HP triple plunger reciprocating pump is of positive-displacement type and widely utilized in intermittent oilfield operations such as acidizing, fracturing and well killing. Its maximum rated brake power is 750 KW (1000 HP), and the stroke is203.2 mm(8”). Plunger diameter is4”or 4-1/2”such as to meet different requirements for pressure and displacement. All kinds of plungers (with different diameters) are equipped with the same power end.
