This is a customer from Chile, want to replace the original two Roots pump. They find our company for an inquiry of vertical multistage water pump. The customer gave the model and basic parameters of Roots pump. After many times of performance and size comparison, they finally confirmed the model CDL4-160,then purchased 6 sets. As the one pump has 16 impellers, so we recommend them buy some impellers and mechinical seals as spare parts. They asked for delivery as soon as possible. The customer is in a hurry to order. However, due to the late time of placing an order before Chinese new year, catching up with the new year's holiday and the stop of transportation, the goods were not delivered on time. Then there was the outbreak of the epidemic in China, the closure of the city and the suspension of work. Then there was the globalization of the epidemic, and the freight rose sharply, so the delivery delayed another four months. Now the goods are on their way. Thanks so much for our client trust and understanding.
