EnviroGear V Series Pump

Introducing the EnviroGear® V Series Asphalt Pump. We understand that pumping asphalt is a challenge as it changes temperatures and can range from a solid to a liquid with a wide variety of fluid characteristics depending on the chemical makeup. And – let’s face it – the competition isn’t getting the job done. EnviroGear V Series pumps address and overcome these challenges, and do so in a way that is safe, reliable and economical. They come in cast iron. 


  • 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
  • Superior pump jacketing provides faster time to temperature of the product being pumped, getting back to production sooner.
