Type THK

Pumps for tank istallation - Type THK

Multistage immersion pumps type TH are characterized by variable immersion depths due to selectable flange positions. They are ideal for pumping clean or slightly polluted fluids such as lubricants, alkaline solutions, acids and solvents used in washing, cleaning, degreasing, pickling and phosphating. Optionally, this series can be equipped with two or three pressure outlets. The use of just one motor with multiple pressure outlets for different duty points results in minimal space requirements compared to the use of multiple pumps.
