In mid-July 2019, a batch of 3000 square rain shelter type mobile flood control pumping trucks ordered by a local water conservancy bureau in Guangdong Province completed the trial run one after another, and the remaining batches of orders are in production. Due to the difference of urban geographic environment, reports on flood control and disaster relief emerge in every region of Guangdong Province in the flood season every year, and the local water conservancy bureau has high requirements for flood control and drainage equipment. Ruiying Machinery has been engaged in the research, design and production of flood control drainage pump truck for more than ten years. With mature technology, the drainage equipment required by customers has been carefully studied. This large mixed-flow pump truck with rainproof roof has been specially designed. At present, the first batch of large flow mobile flood control pumping vehicles have reached the scene of rescue and disaster relief.

October in 2018,enjoy the joy of harvest, a group of grass-green diesel water pump units are ready to be sent to the far-off South American continent to help the Chilean mine drainage project.  In the process of mineral mining, due to the water in the stratum, the rain and the infiltration of water in the river, a large amount of water is collected in the pits around the clock. To ensure the smooth progress of the mining work, it is necessary to drain and send out the water to the surface timely and quickly. At this time, an economical and efficient drainage device can come in handy – it is diesel pump unit. As the world's narrowest country, the Republic of Chile, with a very rich mineral resources, especially saltpeter and copper resources, it enjoys the reputation of “the kingdom of copper mines”. However, in the process of mining mineral resources, the drainage problem is also encountered. Because the pit require the pump unit a high lift relatively, even up to 750m, so, the performance requirements for all aspects of the pump are also high. The relevant procurement are inspecting the pump units in various places. After that, the manufacturer decided to cooperate with our company, and determined the orders for 6 fixed diesel pump units. Pump unit parameter: Diameter: 10 inches、8 inches Flow-rate：750m³/h、500m³/h Head：20 meters Ruiying diesel engine unit has more than ten years of experience in technology development and manufacturing. The products are exported to overseas and have won unanimous praise from customers. In a responsible attitude towards the customer, this cooperation is based on customer requirements, with strict inspection, from material ordering to product commissioning .Single device testing and commissioning has been running for 30 minutes to ensure that no problems will occur.
