A piston type industrial pump comprises a power device (1), a pumping device (2) and a stirring device (3). A connecting pipeline is arranged between the power device (1) and the pumping device (2); the pumping device (2) is fixedly connected with the stirring device (3); the power device (1) consists of at least two power units connected in parallel; the power units comprises hydraulic oil tanks (101), motor oil pump sets (102), and a power unit base (103); and a communicating oil pipe (104) is arranged between the hydraulic oil tanks (101) of the power units. There are at least two groups of motor oil pump sets (102) provided in each power unit. Two or more power units are connected in parallel for providing superimposed power, so that the flow of a hydraulic system can meet a large-volume conveying requirement; in the meantime, all the power units are independent of each other and can work together in parallel or work independently; when one of the power units is fails, only the faulty unit is stopped for maintenance, and the other power units continuously provide power output and are spare to each other.
