Suction Immersion Pumps
TAS/STS301...2000
Axial/semi-open impellers
Suction Immersion Pumps series TAS/STS make it possible to connect to vacuum filters through their simple connection on the suction side (for instance, with a slot screen).
Suction immersion pumps without seals are positioned in the area of unfiltered coolant in the vessel.
With their robust design, they allow operating pressures of –5 PSI to –7 PSI (–0.3 bar to –0.5 bar) on the suction side.
The STS pumps are equipped with the user-friendly 45 degree flange connection which allows for either vertical or horizontal pipe connection and the connection of a pressure gauge.
