The series of BLY485/12, BLY480/10, BLY400/12, BLY320/10, and BLY290/11 crawler-mounted mud pump trucks for mines are often used as supporting products for ZYL kilometer - class drilling rigs. They provide hydrodynamic power and power supply for the downhole motors of the drilling rigs. They can also be used as hydraulic equipment for other special requirements. This series of crawler-mounted mud pump trucks for mines are characterized by small size, light weight, fast travel speed, and diverse flow specifications. The mud pump trucks adopt a load-sensing hydraulic system, which greatly reduces power loss, saves operating costs, and improves operating efficiency.
