Suction Immersion Pumps
TAS/STS301...1001

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 tank.
With their robust design, they allow operating pressures of - 0.3 bar to - 0.5 bar on the suction side.
The STS serie offers a flange with pressure gauge connection port.
The flange can be rotated for either horizontal or vertical pipe connections.
