We had a video conference with a Russian client the other day.The content of the meeting discusses the gap between diesel plunger pairs.

The customer said that the speed of our plunger core is too slow when it slides down, and there is a phenomenon of jamming.so, we

found the drawings and samples sent to me by the customer and conducted another inspection, test. The result did not find any problems.

After discussion with our engineers , the engineer raised a question about diesel impurities. The customer briefly told us about the situation 

of diesel engine impurities in Russsia.So, we preliminary judgment is that the quality of diesel oil in the two countries is different, resulting in a 

requirement for the speed of decline.

we are making a batch for customers to test. Wondering if the diesel plunger pairs passed the customer standard.let's wait and see.
