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.
