34 Series Liquid-Specific Asphalt Internal Gear Pumps
Viking 34 Series™ Asphalt Pumps are designed to handle asphalts, bitumens, pitch, tar, bunker oils, residual oils and related materials that solidify at ambient temperatures. The 34 Series™ pumps are Viking’s simplest asphalt pumps, with a hydraulically-balanced rotor that eliminates the need for thrust control, but also limits the pressures to 100 PSI and less.
These asphalt pumps melt ambient-temperature solids to a liquid state prior to pump startup using integral jacketing for steam or hot oil. Viking Pump 34 Series™ are available as packed pumps only.
