KRAL Oil Burner Pump Stations EK / EL.

Oil burner pump as complete station with additional functions.

These positive displacement pump stations combine all the advantages of the KRAL screw pumps K and L with additional functions for smooth and user-friendly operation. KRAL screw pumps convey highly efficient lubricating fluids, are low-wear, very compact and space-saving.

Operation, materials, components.

  • Delivery rate: 5 to 280 l/min.
  • Max. differential pressure: 40 bar.
  • Temperature range: -20 °C to 180 °C.
  • Housing: Nodular cast iron EN-GJS-400.
  • Screws: Steel, nitrided.
  • Approvals: ABS, BV, CCS, DNV, GL, LRS, MRS, NK, RINA.
  • ATEX: II 2 GD b/c group II, category 2.
  • Heating: Electrical, media or steam.
  • For viscous fluids up to 7,000 mm²/s.

 

The functions of the oil burner supply station of KRAL with K or L series screw pumps can be expanded individually, for example with:

  • Pressure regulation
  • Degassing
  • Flow metering
  • Filter
  • Gas / air separator.

The mounted display instruments can swivel. Left- or right-handed installation can be set up individually at the site.

KRAL offers the optimal solution for every customer requirement. Just ask us, we have probably solved a similar problem already!
