Very high pressure pump cryogenic

摘要

In the pump, each sealing segment of the piston is made up of two adjacent elementary segments, the sections are straight or tapered and are offset, during assembly, 180degre with respect to each other, and an expander, the elementary rings are made of a composite material, which contains more than 50% of bronze, approximately 5% of molybdenum disulphide and the remainder of the pumping ptfe.application continuously in service and a variable load of liquid nitrogen under pressures of 850 bars or more.
