Viking Pump’s Role in the Asphalt Roofing Manufacturing Process
Viking Pumps are essential to the asphalt roofing manufacturing process, supporting every major transfer point from raw material intake to final product application. Whether unloading flux from railcars, transferring it to blowing stills, or metering seal-down and laminate asphalt onto shingles, Viking’s internal gear pumps are engineered for precision, durability, and continuous operation.
Common Challenges Solved by Viking Pump Solutions:
- High-Temperature Handling: Asphalt materials often exceed 450°F (230°C). Viking’s pumps are built with special construction and heating options—like steam jacketing and electric heating—to maintain performance and extend pump life.
- Abrasive Materials: Coating and filled asphalts are highly abrasive. Viking offers hardened components and clearance options to reduce wear and ensure long-term reliability.
- Viscosity Variability: Asphalt viscosity can vary widely. Viking pumps feature adjustable end clearances and extra clearance designs to handle thick, sticky materials without clogging or strain.
- Process Downtime: Roofing plants rely on 24/7 uptime. Viking’s robust design and local distributor support help minimize unplanned maintenance and keep production lines moving.
From tank farms and mix tanks to coater stations and applicators, Viking Pump delivers engineered solutions that solve real-world problems in asphalt roofing manufacturing—making them the go-to partner for reliability and performance.

124E Series™: Electrically Heated Pumping for Asphalt Roofing Efficiency
The 124E Series™ from Viking Pump offers a powerful solution for asphalt roofing manufacturers seeking precision, reliability, and energy efficiency. Designed specifically for environments where steam or hot oil heating is impractical, this electrically heated pump ensures asphalt remains in a liquid state before startup—eliminating delays and reducing operational risks.
124E SERIES™
- Integrated heat cartridges in the bracket and head maintain optimal asphalt temperature, while a thermocouple and controller system provide precise temperature monitoring and control.
- Lower Installation Costs
- By eliminating heat loss through steam or oil piping, the 124E Series™ reduces energy consumption and operating costs.
- The system prevents premature startup by ensuring the asphalt is fully liquefied before operation, reducing wear and potential damage.
