Close-Coupled Rotary Lobe Pump

The TRA Series is a newly redesigned, high-efficiency close-coupled rotary lobe pump that optimizes the performance of the traditional TR series. By utilizing an integrated direct coupling assembly, it shortens the overall length by 100mm to 250mm. Wrapped in mirror-polished stainless steel, this compact monobloc pump eliminates traditional paint-peeling risks, delivers the highest mechanical efficiency, minimizes internal slippage, and ensures a longer service life in full compliance with CE, 3A, FDA, and GMP sanitary standards.

Key Benefits & Features

  • Redesigned Compact Structure: The integrated direct-coupling assembly reduces total length by 100-250mm, significantly saving installation space with a highly compact footprint.
  • Premium Mirror-Polished Finish: Fully enclosed in high-grade stainless steel with a mirror-polished finish. This delivers an elegant appearance and eliminates paint-peeling risks to ensure workshop hygiene.
  • Maximum Mechanical Efficiency: Direct shaft assembly eliminates the power loss caused by traditional elastic couplings, reducing operating noise, minimizing wear, and increasing overall working efficiency.
  • 3A & CE Approved Hygiene: The zero dead-zone structure prevents bacterial growth, ensuring that both construction and production quality meet strict FDA and GMP rules for sensitive fluid handling.

Technical Configuration Options (Drive Systems)

Select the ideal drive system for your upgraded direct drive lobe pump:

  • TRA-I Model: Equipped with a manual stepless speed regulator, ideal for steady flow tasks. It can also accept an external VFD inverter for added process flexibility.
  • TRA-II Model (6-Pole Motor): Powered by a high-torque 6-pole motor that requires a VFD inverter for speed control, offering a wide speed range and high automation.
  • TRA-III Special Hopper Model: A unique specialized configuration featuring a top-mounted large feed hopper and a full stainless steel outer cover with manual stepless speed regulation. It is the ultimate solution for highly viscous, high-concentration pastes with poor natural flowability.
  • Mobile Trolley Option (Optional): Mounted on a mobile wheeled cart, making it the perfect solution for multi-station workshops without fixed working positions.

Wide Range of Applications

This compact direct drive rotary lobe pump excels in transferring thick, viscous, or sensitive products:

  • Food & Beverage: Dairy, latex, chocolate, syrup, cheese, wort, beer, and soft drinks.
  • Fruit Concentrates: Pudding, jam, jelly, tomato paste, and high-concentration purees (via TRA-III Hopper type).
  • Cosmetics & Pharma: Face creams, detergents, hair gels, essential oils, medicine extracts, emulsions, pill pastes, proteins, and plasma.
  • Chemical Industry: Dyes, fats, solvents, resins, and polymers.
