Features
The V Series Asphalt Pump innovative design includes a wide variety of new and standard-setting features that have established a series of industry firsts within the asphalt market.
Industry’s Largest Jacketed Surface Area
The V Series Internal Gear Asphalt Pumps feature up to 35% more jacket surface area than the competition, which improves system reliability by incorporating the following features:
- The unique ability to utilize the jacketed head and pressure relief valve (PRV) simultaneously
- Jacketing located behind the pump rotor, which removes a known cold spot that can result in hard startups and premature pump and seal failures
- The industry’s largest jacketed surface area on the pump case and PRV that enables uniform heating whether using steam or hot oil
First Direct Replacement for Viking® 34 Series Pump & Parts

First drop-in replacement for the Viking® 34 Series asphalt pump. Replacing an existing Viking gear pump usually requires no modification to the piping, driver, baseplate or coupling, while also keeping flow rates unchanged. V Series components are also part-for-part interchangeable with the Viking 34 Series asphalt pump and offer very specific design enhancements to improve reliability.
Rotatable Flanges

Greatly improves fluid circulation through the magnetic coupling, resulting in lower operating temperatures, longer magnet life, and more effective cleaning and flushing processes.
High-Strength Ductile Iron Gear Material as Standard

High-strength ductile iron is V Series Asphalt Pump standard offering with other hardened material component options available to provide improved pump life:
- Surface hardened case, head, rotor, idler and shaft
- Special high-temperature hardened steel idler pin
- Hardened cast iron idler bushing, RBS radial bushing, and stationary thrust washer
