Description
The magnetic drive multistage self-priming centrifugal pumps of the TBK series are pumps with star-type impellers.
The magnetic drive multistage self-priming centrifugal pumps of the TBK series are designed according to an innovative design and high quality components. They guarantee high performance and reduced power losses.
The magnetic drive multistage self-priming centrifugal pumps of the TBK series have suction and priming capacity up to 8.5 m.c. of vacuum and allow to pump mixtures of liquids and gases.
TECHNICAL SPECIFICATIONS
