Product Description
Asphalt pumps are engineered specifically for handling hot, thick, and sticky fluids like asphalt, tar, bitumen, and heavy oils.
Key features of asphalt pumps include:
- Constructed with jackets for heating (hot oil, steam or electric) to maintain fluid viscosity.
- Made from abrasion-resistant and high-temperature materials.
- Typically use internal gear pumps for high viscosity handling.
- Handles temperatures up to 400°F (204°C) or more.
- Seals and clearances designed to manage thermal expansion.
Asphalt Pumps
Clean asphalt is an oil based liquid with no fillers, and is typically handled at elevated temperatures to reduce viscosity. Asphalt pumps need a source of heat like jacketing or electric heat to keep the asphalt from solidifying in the pump.
Viking’s 1224A-ASP pumps are designed specifically for handling asphalt, bitumen, pitch, bunker oils, residual oils and related materials that solidify at ambient temperatures. These pumps come standard with Viking’s O-Pro® Cartridge seal to prevent process fluid from leaking out of the pump. ASP1 models are suitable for clean, non-abrasive asphalts. ASP2 models are designed for abrasive applications such as filled asphalts used by manufacturers of asphalt roofing.
Vikings 34 series feature a fully jacketed pump to rapidly deliver heat directly to the stuffing box, casing and head. Jacketing is suitable for hot oil or steam for enhanced application flexibility. This is a simple, economical design for transfer and delivery of asphalt and bitumen at low to moderate pressures.
