Definitions

  • the invention relates to a piston pump head of a high-pressure piston pump with a mechanical or hydraulic drive for delivery pressures above 2000 bar.
  • Both high-pressure piston pumps and high-pressure diaphragm pumps are used to pump thin-viscosity, non-lubricating liquids to high pressures, especially pressures above 2000 bar.
  • the stuffing box made of soft materials generates less frictional heat and therefore less wear.
  • the pressure-bearing parts - particularly the piston pump head - which are highly stressed by extreme pressure amplitudes are less stressed per unit of time.
  • the design of these slow-running high-pressure piston pumps is very large and therefore expensive.
  • the piston pump head is made of age hardenable steel.
  • These are steels with special alloying elements, which, based on an intermetallic compound, reach their high strength with sufficient toughness and corrosion resistance by storing the finished part at 480 o C to 600 ° C under inert gas. Specifically, the steel is used 1.4534 and aged at 540 0 C.
