TrumpJet Flash Mixing technical features

TrumpJet Flash Mixing does not use water for dozing and mixing of paper chemicals

Injection of chemicals using part of the process stream

Instead of fresh water or clear filtrate, injection liquid is a part of the process stream – typically circulated headbox feed stock taken from the initial process flow.

No fresh water has to be added, heated, pumped or cleaned for the purposes of chemical mixing. This leads to significant water and energy savings and reduces production costs, CO2 emissions, wastewater, and overall environmental impact.

TrumpJet Flash Mixing mixes chemicals homogeneously across the entire volume within 2 seconds

Optimal mixing location for maximum efficiency

TrumpJet® injects chemicals with a high speed, large open area liquid jet. It quickly disperses chemicals into tiny droplets that react uniformly with process media.

Homogeneous mixing across the entire volume within 2 seconds allows chemical dosing just a few meters before the headbox, optimizing chemical effect while minimizing chemical consumption. It also improves paper formation and end product quality.

TrumpJet Flash Mixing Reactor mixes various chemicals very close to one another, just before the headbox.

TrumpJet Flash Mixing Reactor for multiple additives

TrumpJet Flash Mixing Reactor enables mixing various chemicals, even with opposing charges, very close to one another in a compact reactor zone located just before the headbox. The result is excellent chemical distribution and dispersion, fast control response, a cleaner process and improved machine runnability.

Uniform mixing and optimized chemical dosing location reduces chemical consumption typically by 20-60%.

“Your TrumpJet technology pretty much revolutionized the way everyone thinks about additive injection systems.”

Larry Montague
President of TAPPI

Cleanliness of the chemical feed system is a must

All components of the TrumpJet injection and chemical feed systems are meticulously designed, engineered, and manufactured to prevent scaling, fiber spinning, and the formation of chemical, filler, and fiber lumps.

All joints are flush fitted and all surfaces are polished and electropolished to avoid the formation of harmful dirt deposits.

TrumpJet® hygienic injection pump for excellent runnability

  • Smooth edge-free hydraulic design
  • Prevents fiber and dirt build-up
  • Effective also for extra long fibers
  • Process cleanliness and efficiency
  • Low pulsation
  • Smart flow measurement and control
  • Light and compact
  • Easy installation, disassembly and maintenance
