The utility model relates to a be used for fracturing blender truck closed type pump double pump confluence system, including the hydraulic pump aggregate of getting on the bus, the hydraulic pump aggregate of getting off, motor low pressure hydraulic fluid port, motor high pressure hydraulic fluid port, a logic valve other end of the hydraulic pump aggregate of getting on the bus is connected with a logic valve other end of the hydraulic pump aggregate of getting off, motor high pressure hydraulic fluid port, two other ends of logic valve of hydraulic pump aggregate of getting on the bus are connected with two other ends of logic valve, the motor low pressure hydraulic fluid port of the hydraulic pump aggregate of getting off, a logic valve other end and the motor high pressure hydraulic fluid port of hydraulic pump aggregate of getting off is connected, motor low pressure hydraulic fluid port, motor high pressure hydraulic fluid port are the motor fuel feeding. The utility model has the advantages that: through the socket pump with the same motor connection of upper and lower car hydraulic pump aggregate, realize that two sets of pump system for the motor fuel feeding, utilizes high -low pressure oil to realize crisscross fuel feeding, at the on the premise of that does not influence the work of upper and lower car hydraulic pump, the get off problem of underpower of solve.
