Fuel pumps
The self-priming or normal-priming Dickow fuel pump made of spheroidal graphite cast iron GGG40.3 or cast steel 1.7706 EN 10213-2 was specially developed for pumping hydrocarbons in refuelling systems and tank farms. The pumps are available in single-stage or multi-stage design and with side channel principle working venting device. The pump nozzles of the self-priming fuel pumps are therefore always arranged upwards. To achieve the lowest possible NPSH values, the suction housings are designed as inlet spirals and are one nominal size larger than the pressure flanges. ATEX version for applications in EX zone 1, or with magnetic coupling for increased safety requirements are available. Performance ranges of the HZS/HZSM pumps, Q max. 600 m3/h, H max. 500 m, BT 100 °C and for the HZ/HZM pumps up to 200 °C are covered.
Fuel pumps for the following media
- Diesel
- Gasoline
- Kerosene
- Aviation fuel
- Petroleum
- Liquid gas
- Water
Applications of the fuel pumps
- Storage of diesel, gasoline, aviation kerosene, kerosene
- Refuelling of all types of aircraft, helicopters
- Filling of high tanks
- Pumping of water in hydrant systems at airports
- Delivery of liquefied gas, transfer pumps in refineries, i.e. for filling liquefied gas tankers
Features of the fuel pumps
- high process reliability
- large dimensioned pump shaft and roller bearings
- Bearing bracket with oil-lubricated with generously dimensioned rolling bearings outside the pumped medium
- Design with plain bearing SiC, which is supplied with the medium to be pumped via the discharge connection to prevent dry running.
- Oil level in the bearing bracket due to automatic oil level control for constant level
- Mechanical seal housing pressurized with cooling water
Sealing
- Mechanical seal carbon/SiC pairing
- Magnetic coupling, depending on operating temperature with high temperature magnets
