The GD range is a semi-remote bearing design pump. In this design the shaft bearings do not come into contact with the product being pumped. This is important for applications where the liquids being pumped could have a detrimental effect on the shaft bearings. These pumps are NFPA20 compliant and can handle viscosities down to 1 centistoke. These pumps are suitable for foam type applications involving testing with water or extremely low viscosity items.
Albany has found an increasing preference in the purchasing of water turbine drives for foam concentrate pumps. Both reliable and safe, the shear rate within the pump is sufficient to reduce the viscosity. These kinds of liquids have a resistance to flow, so need the extra force delivered by the GD range for optimum performance.
Paramount for use in safety applications, our GD range of water and foam pumps are best suited to the Fire industry, as well as the General & Chemical market. We find our C style pumps are fitted mostly in offshore jetties, fixed installations in tank farms or refineries, and also shipboard for fire protection.
- Has foam concentrate pressure from 8 to 19 bars
- Uses water supply pressure of 7 to 18 bars
- Up to 3,000 cSt viscosity at 500 rpm
- Suction lines should be as short as possible, allowing for a generous diameter
- Can handle thixotropic foam liquids
Our GD range of pumps is specifically suited to pumping foam and water cargo, making the range the perfect solution for Fire related applications, and as safety precautions in the demanding Oil & Gas industry.
- Pump casing: Available in gunmetal.
