Recently, Hunan Oil Pump Co., Ltd. has successfully developed eight new cooling water pumps for the United States Constrains, the M11 and ISM02 series, and has taken a new step for Xiang Pump to enter the international market. Since the previous work was done very solidly and the technical quality problems were solved, the two pumps fully met Cummins's technical conditions and the quality requirements of the product parts. In the trial production process, Xiang Pump successively solved each of the 10 major items and 60 items related to roughs, machining, impellers, and bearings, which were proposed by the other party, and passed inspections and approvals of Cummins experts.
