Effective waste water pumps for a wide range of applications The self-priming submersible pumps are perfect for pumping water out of ponds, water buckets or flooded cellars. With the VT submersible pumps, you can efficiently extract and pump out water even when it is heavily soiled (up to 5 mm particle size). Thanks to the built-in and adjustable float, you can precisely set the water level and prevent water basins from overflowing. Our submersible pumps suck the water down to a level of approx. 5 mm, so that even deeper-lying water residues are removed.
