  • Designed for heavy industry pumps pumping very viscous media, such as asphalt or pitch transfer pumps under high temperature towers, large heavy oil transfer pumps and refining process pumps.
  • Prevent hazardous emissions of acidic, caustic, corrosive, volatile and toxic media.
  • Ideal for high viscosity applications, such as emulsions, latex and rubber.
  • Reliable sealing for high temperature, high or varying pressure processes.
  • Engineered to cope with process fluids prone to crystallize, or with a high percentage of abrasive solids or powder.
  • Withstand dry running involved with frequent starts and stops.
  • Used for dry-running applications in specialty equipment, such as air transportation blowers.
  • Ability to tolerate short intermittent dry-running in batch charging and discharging equipment.
  • Widely used in the refining, petrochemical, rubber, chemical, food and beverage, pharmaceutical, pipeline transportation, renewable energy, and power generation industries.
