Floating Suction Unit for Horizontal and Underground Tanks

Horizontal, mounded and underground tanks need a floating suction that fits through a manhole and works in a short liquid depth. The Vens unit for these tanks uses a short pivoting arm with a compact float, connected either to a side outlet or to a riser pipe that comes up through the manhole cover.
On riser arrangements a foot valve can be fitted so the vertical pipe stays full and the pump keeps its prime. Pads under the float and arm protect internal tank coatings when the level is low.
Underground fuel tanks at airports, depots and fuel stations
Horizontal day tanks and bullet tanks
Mounded and semi-buried storage
