Wright Pump TRA20 Series Sanitary Positive Displacement Pumps
The reliability of Wright Pump’s positive displacement circumferential piston pumping principle has been proven over many decades. Its robust design and easy cleanability make it applicable for all sanitary fluids.
Wright Pumps’ gentle action on shear-sensitive liquids, or slurries with soft solids, makes them the preferred technology for all areas of food processing, beverage and cosmetic manufacturing, worldwide.
Wright TRA20 Features
- Time tested and proven circumferential piston design.
- Exceptional engineering and manufacturing quality.
- Parts are interchangeable with Waukesha Universal II series pump parts.
- Wright TRA20 pumps are drop-in replacements for equivalent sized Waukesha Universal II pumps.
- Wright can remanufacture TRA20 series or Waukesha Universal II series pumps up to four times.
Choosing between TRA20 and TRA10 series Pumps
- The TRA20 series allows optional Clean-In-Place design. CIP-ing can reduce cleaning time and labour between batches.
- Most TRA20 models offer higher pressure capabilities than their equivalent TRA10 model, all of which are rated to 14 Bar, except the model TRA10 0450, which is rated to 27 Bar.
