VERY HIGH PRESSURE PISTON PUMP

摘要

The pump can compress a transport medium (20) at a pressure of up to approximately 22 kbar. The very high pressure seal is made of a pressure-compensated ice seal which operates without leakage and minimum friction. To limit the generally very high frictional forces in the ice seals, a rotational movement is superimposed on the translational movement of the piston (10). The complete machine is regulated by means of a microprocessor as a function of the operating parameters and flow output. The very high pressure seal has a long service life even when used in very high pressure ranges.
