Installation
Installation possibilities
DF-100 pumps are very easily configured and easy to install.
Flooded:
The pumping system was designed with positive pressure at the inlet. This is the best possible installation when you need to evacuate the liquid from
the drum or tank, or when working with viscous fluids. Not recommended for hazardous fluids.
Self-priming:
DF-100 Pump is designed to generate vacuum. It is possible to evacuate all the air from a hose or pipe without damaging the pump. Maximum suction
height is 14.8 ft (4,5 m), with the suction hose empty and up to 23.6 ft (7,2 m) with the hose primed.
Submerged:
All pumps DF-100 can be immersed in fluids. It is important to verify that all components that are in contact with the fluid are chemically compatible.
In this case, air exhaust and fluid must be carried by hoses (optional air connection).
