Hydraulic gear pumps of BG20 series are external gear pumps of group 2 made of alumunium alloys. They are designed for general use in the medium pressure range. Studied design, good materials, excellent workmanship and quality control determine the better performance and versatility. They are used in industrial and mobile applications.
Maximum continuous pressure up to 290 bar, the displacement range from 4 to 26 cm3 / rev.
Hydraulic external gear pumps BG20 are manufactured in many varieties of flanges, shafts and hydraulic connections. They meet all the requirements of gear pumps in hydraulic open circuits. They can be prepared and delivered as multi-flow pumps.
Features:
- Displacement: from 4 to 26 cm3 / rev;
- Rotational speeds from 500 to 4000 rpm;
- The maximum output pressure from 170/190 to 250/290 bar (continuous / peak);
- Required power: 3.5 to 13.5 kW.
Advantages:
- Small size;
- High performance in its category;
- Two-way turnover labeled versions of pumps;
- Durability.
Usage
BG hydraulic pumps are used in a wide range of agricultural machinery, construction – in mobile hydraulics, and at the same time are used as a component of hydraulic power-packs and power supplies.
