New pumps meet the challenges of handling tough abrasives
A new range of internal gear pumps said to be suited to applications involving asphalt and bitumen have been added to the Viking Universal Series of pumps available from Michael Smith Engineers. Viking Pump has continually developed its range of Universal Seal internal gear pumps and the new ASP series is another example of an upgraded option for handling the toughest abrasives.
When pumping asphalt, bitumen and other similar abrasives, pumps have traditionally been sealed with packing which must continually leak to stay lubricated. These two new options, the ASP1 and ASP2 are supplied with Viking’s O-Pro cartridge seal which uses O-rings in combination with a lubricating grease. This ensures a robust seal that improves operational efficiency as it doesn’t need periodic repacking or re-tensioning of the seal gland which eliminates the risk of leaks and prevents loss of product and the associated clean-up costs.
Both options are designed specifically for handling asphalts, bitumen, pitch, tar, bunker and residual oils and other similar materials that solidify at ambient temperatures. They are designed to melt ambient temperature solids to a liquid state prior to pump start-up by using integral jacketing for steam or hot oil.
The ASP1 model is said to be an ideal option when pumping clean, non-abrasive liquids, while the ASP2 model is said to be ideal for pumping more abrasive liquids in applications involving filled asphalts often used for asphalt roofing and sealants.
