The first generation of these pumps were engineered in the 1940s for truck-mounted applications. They were bolted to the chassis and driven off the PTO. That harsh environment established design features that would define the product line: a footed mounting bracket, a rotatable casing, and a thrust bearing housing for precise end clearance adjustment. The second generation saw a change to the bearing housing (while maintaining the same bearings) and an expanded range of sizes, material-specific model numbers and the offering of integrally jacketed versions.

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.

Welcome, in this quick tip video we will guide you through the installation of a stuffing box component mechanical seal in Viking Pump’s with the U-Plus™ bracket.

Lubricate the shaft and inside of the rotary member of the seal.

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.
