Pompetravaini - Model TBH -Multistage Self-Priming Centrifugal Pumps

• Capable of handling mixtures of gas and clean liquids.
• Suction lift to 8,5 m.w.c.
• Low operating speed for extended life, low vibration, low noise level and maximum reliability.
• Making use of the lateral channel principle, the open "star" type impeller is hydraulically balanced and enclosed between the suction and discharge port plates to form the pumping stage.
• Stages are mounted in series to give proportional higher discharge pressures with constant capacities.
• Impellers are individually hydraulically balanced thus end thrust forces to bearings are eliminated.
• Mechanical seals are standard and unified to UNI EN 12756. Optional double mechanical seals back to back or tandem. Cooled or heated seal housings are available.
• Reduced number of components is achieved by design innovation.
• Variety of materials are available to meet specific requirements.
• Capacity up to 70 m3/h and head up to 40 bar.

For the transport of corrosive, toxic, polluting and foul-smelling liquids and in all cases in which there should be no leak to the outside, the TBK version with magnetic drive obtained from TBH is also available.
