What is filled asphalt? And how do you pump it? Filled asphalts contain particulate and are used in the production of roofing materials. They are typically handled at elevated temperatures to reduce viscosity. So what's required to pump filled asphalt? Filled asphalt will solidify if it cools. Jacketed pumps allow heating with hot oil or steam, and electrically heated options are also available. Filled asphalts can be quite abrasive. Hardened parts and materials help the pump withstand abrasive wear.

What is asphalt cement? And how do you pump it? Asphalt cement, or clean asphalt, contains no fillers and is an oil-based liquid. It is typically handled at higher temperatures to reduce viscosity. Asphalt cement is used in a number of applications, but the most common include paving roads and providing waterproofing for building materials. So what's required to pump asphalt cement? Asphalt cement can solidify if it cools. Jacketed pumps allow the pump to be heated with hot oil or steam prior to startup, preventing product from solidifying inside the pump.
