KRAL Pump Stations EK / EL

Oil burner supply station – oil burner pump with additional functions

Each type of burner has different requirements to fulfill, depending on the system concept.

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

 

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!
