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!
