Description
The multistage self-priming centrifugal pumps of the TBH series are pumps with horizontal mounting vertical suction and discharge flanges.
The multistage self-priming centrifugal pumps of the TBH series are capable of handling mixtures of gas and clean liquids and are suitable for low flow and high pressures.
The multistage self-priming centrifugal pumps of the TBH series work at low operating speed for extended life, low vibration, low noise level and maximum reliability.

APPLICATIONS
Pumps series TBH and TBA are suitable to handle clean liquids, corrosives, hot or cold in the chemical, petrochemical, pharmaceutical, food industries, etc.
- Removal of condensates and distilled liquids.
- Solvents and liquified gases applications.
- Boiler feed applications.
- Removal or liquid from processes under vacuum.
- Filling stations and transfer of LPG and liquified gases.
- Fire fighting systems and autoclaves.
- Potable and sanitary systems in the naval industry.
- Spray washing installations.
CONSTRUCTION
The self-priming pumps series TBH and TBA utilize 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. The magnetic drive pumps series TBK and TBAK derive from the series TBH and TBA. They are suitable to handle hazardous, toxics, odorous or polluting liquids and other applications where zero liquid leakage is desired.
